Geotextiles in construction. Geotextile: application in the country, description, reviews. The use of geotextile when planning a garden landscape

Geotextile- non-woven, woven or knitted material, fabric with high strength and other useful properties.
Nonwoven geotextiles are made from polypropylene or polyester (sometimes with the addition of fibers of plant or animal origin), by needle-punching, or by thermal or chemical bonding of threads.
Woven geotextile (geotextile) is obtained by interweaving several threads (usually at right angles). Knitted geotextile (geotricot) - loop weave. Depending on the method of production, the properties of geotextiles and their area of application change.

In general, all types of geotextiles have the following properties:

elasticity - the material is resistant to stress and can perform a reinforcing function;
elongation at break (up to 45%); tear and puncture resistance;
filtering ability - the pores of the material are not silted up and are not clogged with soil particles;
resistance to ultraviolet radiation, practically does not decompose, - environmentally friendly material.

In this regard, geotextiles are used where separation, partial reinforcement, drainage, filtration are required. The fields of application of various geotextiles are very wide - from medicine, household appliances, furniture production, packaging, to agriculture, construction of houses and roads.

Dornit- this is one of the varieties of geotextiles - domestic non-woven geotextiles.

It is made from polypropylene needle-punched method.

This material is characteristic in that it does not rot, mold and fungi, insects and rodents do not start in it, plant roots do not grow through it. It is chemically resistant, inert to the effects of chemical compounds in groundwater and soils. This material passes water well, but does not silt up or clog up with soil particles. Dornit withstands heavy loads well; when used as a reinforcing material, it practically does not deform. Resistant to tears and punctures. Isotropic - has equal properties in all directions. At breaks, it lengthens by 40-50%, that is, it continues to perform its functions. Its service life is at least 25 years. It retains its properties in the temperature range from - 60 to + 100 degrees C. It can be bonded both mechanically and thermally.

Dornit is produced in rolls. 1.6-5.3 m wide, 50-150 m long, different density, from 90 to 800 g / sq m. Due to its special properties, dornite is used in the following areas:

In road construction, - to separate layers. Its use can significantly reduce the cost of crushed stone and sand, which is required much less. Dornit does not allow mixing of soil and bulk base, increases the bearing capacity of the roadway, prevents the formation of ruts and cracks in the road surface. Compared to other geotextiles, dornite is more resistant to damage during installation.
For strengthening slopes and slopes. Dornit, laid under the slabs, prevents soil washout at the slab joints and also reduces tensile stress by stabilizing the slope.
When arranging embankments- dornit separates the filled soil and the base.
When creating decorative reservoirs or hydraulic structures- prevents mixing of soil and sand, germination of roots, reinforces, redistributes the load.
In drainage structures- Drainage pipes are wrapped with a mandrel to prevent clogging.
When creating and operating "green roofs". Dornit is placed under the soil layer for drainage, filtration and - to prevent the destruction of the fertile layer, it allows the use of cheaper coarse-grained materials.

The material is easily laid, since the rolls are quite small. Therefore, transportation costs are also low. During storage, transportation and laying, the dornit does not absorb moisture, does not grow moldy, it is not spoiled by rodents, etc.

When laying the dornite, an overlap of 10-12 cm is made.The underlying surface is specially prepared (profiled and compacted, trees and shrubs are cut at the same level with the surface) so that there are no irregularities of more than 5 cm.The rolls are rolled manually in the longitudinal or transverse direction, periodically leveling and fastening to the ground with anchors (or in another way). If the canvases are pre-connected, this will reduce the amount of overlap. When backfilling the dornite, a direct run over the canvas should be avoided. Construction machinery may only proceed after compaction of the minimum fill layer.

Geotextile in our time is an extremely necessary thing in home construction. And you need to know exactly which brand with which qualities to choose for certain works on your site. In drainage systems, the function of geotextiles is to ensure the stability of the entire complex, prevent soil subsidence in the drainage trench, and also with its help, the diffusion of crushed stone into the water is excluded. In any drainage system, a geotextile is a filter that prevents siltation of the drain pipe or drainage material.

Geotextile is a building material made of synthetic, mineral, basalt or fiberglass, in the form of ribbons, linen and bulk structure. It is used in construction and other industries (medicine, light industry) for various purposes: for reinforcement, protection, drainage, filtration, hydro and thermal insulation in soil, road surfaces, buildings to separate layers of materials of different fractions and, accordingly, create layers. On personal plots, due to its accessibility and convenience, it is more often used in drainage systems.

The use of geotextiles in household plots for drainage

If the site is on soils with a high groundwater table, in a lowland, if there is a river nearby or every rain becomes a natural disaster, then you cannot do without drainage systems that drain excess water from the site. This water washes away the foundations of buildings, provides the prerequisites for subsidence of the house and conditions for the development of mold in the basement, does not allow plants to develop normally, and creates wetlands.

Not a single modern drainage system on the site can do without geotextiles. She needs to be protected. Escaping water fills the drainage material with soil particles, over time this clogs the system and it stops working. Eco-friendly and durable geotextiles are widely used in private household plots.

It ensures the reliability and stability of the drainage system:

allows water to pass through and helps to drain it;
prevents the mixing of drainage filler, coating and soil;
takes on part of the load;
prevents soil subsidence in the system, clogging of drainage pipes with soil particles, penetration of drainage crushed stone and sand into the water;
resists silting (covering over time with water sludge and clay) of the drainage components - pipes and material.

Ideal for both open and closed drainage systems.

2 Types of geotextiles for drainage

Geotextiles are divided into types according to their composition and manufacturing method.

Geotextile composition

Geotextiles are usually made from polyester (PES) or polypropylene (PP). For nonwovens, polyamide or fiberglass is sometimes used. In addition, there is a non-woven geotextile, which may contain threads of natural origin. If wool or cotton thread is added, then such geotextile is called blended.

Preparation method

According to the manufacturing method, geotextiles are divided into geotextile (woven or knitted fabric) and non-woven geotextile.

According to the manufacturing method, geotextiles are divided into two main types: woven and non-woven.

Woven geotextile has high strength characteristics, is resistant to deformation processes and is used as a separating reinforcing layer, for example, in road construction. Nonwoven has higher permeability properties, it is often used as a material for the device of drainage systems (even on the most difficult soils) and in landscape design.

Geofabric

Woven fabric made of glass or polyester fibers is of two types. Sometimes it is a simple weave of threads (1-3 millimeters thick, formed from fibers), which is called "weft" - "warp".

Woven geotextile - plain weave

Sometimes this weave is provided with different threads. For example, a longitudinal warp - high modulus polyester of a relatively large cross section - is interwoven with transverse thin polyamide weft threads. This gives tremendous tensile strength.

Woven geotextile from different filaments has high tensile strength

Sometimes these are not threads, but strips of synthetic material. And sometimes - just perpendicular threads or stripes are connected by a third thread.

Polyester and polypropylene threads are stitched in a mutually perpendicular direction, which gives high tensile strength

Woven geotextiles are very durable, have little deformation and have good water permeability. Due to its high strength, it is often used for drainage in cases where it is set up at great depths, for example, for foundation drainage.

Geotextile also includes warp-knitted geotextiles - knitted (knitted, braided), obtained by knitting loops, without weaving. But it is not very durable: as soon as the canvas gets damaged, it begins to unfold, like any knitted thing.

Warp-knitted geotextiles are more environmentally friendly but less durable

Non-woven geotextile

A nonwoven fabric consists of synthetic fibers or threads that are oriented (in one direction) or randomly. These are threads made of polypropylene or polyester, which, in turn, are monofilament (one endless thread) or staple (pieces of 5-10 centimeters). Staple geotextiles are not used for drainage, they are soft and fragile.

"Non-woven" is fastened in different ways: needle-punched, thermal (welding), mechanical (pressing), physicochemical methods (extrusion) or their combination (for example, injection molding), as well as by the method of hydrobonding.

Needle-punching means that the needles pierce the fiber, thereby creating a felting effect. It turns out something like synthetic felt. It is highly stretchable, but very flexible and well suited for wrapping pipes with closed drainage.

Needle Punched Nonwoven Geotextile Is Like Felt

If it is rolled with a hot roller (calender) and blown with hot air, a heat-set (calendered) geotextile is obtained. It becomes less plastic, thinner and much stronger, but it does not allow moisture to pass through. Therefore, it is rarely used in drainage.

Heat-set geotextile is made from endless polypropylene fibers using needle-punching technology and heat treatment

Thermally bonded non-woven geotextiles are made by melting (welding), are highly permeable and durable, have the most important qualities: unlike other varieties, they are not afraid of ultraviolet radiation; not susceptible to silting, resistant to mold and mildew; designed for all types of drainage systems and landscaping.

Thermobonded geotextile is durable and practical

Since the needles damage the monofilament during the needle-punching method and a loss of strength occurs, the thinnest jets of water under high pressure are often used. Such hydro-bonded geotextiles are so durable that they are used even in the construction of runways; it is very resistant, also not afraid of ultraviolet radiation and prevents the development of bacteria and mold. Therefore, it is widely used for all types of drainage.

Geotextile structure

The structure of the geotextile provides it with unique properties not to accumulate moisture in itself, that is, not to dampen it, without letting water through.

Geogrid - non-woven material: staggered polymer strips interconnected to create cells.
Geostab geogrid - bonded tapes made of high-strength polypropylene yarn with stabilizers for the material's resistance to UV rays
Geogrid is a flat material: strips are either intertwined or connected by other methods to each other perpendicularly or at an angle. In this case, the cells are much larger than the thickness of the strips.
The SSNP-Highway geogrid consists of a complex of two threads, which are fastened together by stitching a third, treated with a bituminous solution
Geomat: fibers or threads are chaotically and loosely bonded by chemical, thermal, mechanical methods. It is a flexible, lightweight air and water permeable geosynthetic material with a chaotic three-dimensional structure, which provides effective protection against soil erosion both with vegetation and before it appears.
Geomats can be used in combination with various non-woven geotextiles and polymer geonets
Geocell is a bulky nonwoven fabric with large cells.
Geocell "Armosot" (Russia) is very large
A geo-strip is a narrow, not more than 90 centimeters, strip that has technologically shaped edges or is obtained by cutting out a larger width from geosynthetic material.
The geo-strip is not wide at all
Geomembrane - geotextile impervious to water; used for the bottom of artificial reservoirs and streams.
Geomembrane is impervious to water
Clay-geosynthetic geomembrane - a geomembrane with a clay layer, is used for the same purposes.

Geomembrane clay-geosynthetic Geosynthetic Nonwoven is intended for construction of waterproofing
Geomembrane bitumen-geosynthetic - a geomembrane with a bituminous layer.
Earthenware - three layers, outer layers - needle-punched geotextile, between them - clay. The layers are stitched together.
Bentonite is the same, but inside is sodium bentonite, which becomes waterproof when wet.
Voltex bentonite mats - the most modern insulation material
Geocomposite - at least two, and more often - many layers of different geotextiles. It is divided into reinforcing (armogeocomposites) and drainage (geodrains) options.
Geocomposites are the most commonly used drainage geosynthetics

Geotextile Specifications

Specifications include:

high strength - tensile strength up to several hundred kN / m, while elongation is not more than 18%;
high density - ranges from 80 to 1200 g / m2.

3 Choosing a geotextile for drainage in the garden

In an open drainage system, drainage ditches are covered with geotextiles.

Without absorbing moisture, geotextiles retain their original weight at any moisture

Geotextiles are also used to wrap pipes in closed drains.

Geotextile in a closed drainage system separates rubble and soil

Selection factors

Geotextiles are selected depending on certain geological conditions at the site of the system.

The most important factor is density. The higher the density (web mass per square meter), the smaller the pores, the lower the water throughput (and the higher the water retention capacity), which entails silting of the system. Therefore, only low density geotextiles (150–300 g / m3) are used for drainage. The optimal pore size is 175 microns. But if the density is too low, the strength will suffer greatly.
The filtration coefficient (transverse coefficient), showing the water permeability, is calculated by the formula: the height of the liquid column that the material passes through itself at a given pressure at a given time. Ideally, it should be 100–150 m / day, up to 300 m / day, and is selected depending on the height of groundwater, the amount of precipitation and soil permeability. If there is a large amount of water entering the site, geotextiles with the highest transverse coefficient should be chosen.
You can use all of the above types of hydro-textiles, focusing on the conditions of your drainage. But it is still advisable to use polypropylene geotextiles made of smooth monofilament, elastic and durable. It is more resistant to siltation.
It is also desirable to use thermally bonded geotextiles. Needle-punching silts up faster and starts to pass water worse.
Mixed geotextiles must not be used: non-synthetic components (wool, cotton) quickly begin to rot and clog pores.
The mechanical characteristics must also match the need. The tensile strength must be at least 1.9–3 kN / m (longitudinal strength) and 1.5–2.4 kN / m (transverse). The resistance to punching is selected based on the material of the drainage layer that you have (crushed stone, etc.), the depth of the drainage system (soil pressure on it), the tendency of the soil to subsidence and displacement. Under normal conditions, it is enough for the resistance to be 400-500 N. If you have bought very large crushed stone and projected a large depth of occurrence (for example, when draining the foundation, where it sometimes reaches two or more meters), then it is better to choose the resistance more than these figures ... All these data must be indicated by the manufacturer on the packaging.
You can also choose the width of the web: it can be from the width of the tape (20 centimeters) to five meters and depends on the manufacturer.
The economic factor is of great importance. It is necessary to find a harmonious correspondence between price and quality. The price, as a rule, is set for one square meter, but for narrow varieties it is also per roll. Usually the price is low: from 10 to 20 rubles per m2. Of course, good geotextiles are not completely cheap, but you can always find either high-quality domestic analogs of imported expensive materials, or choose exactly the geotextiles for your conditions: an open or closed drainage system, the presence of collectors or natural drainage into a river or sewage system, the amount of water inflow to the site. Perhaps you do not need super-expensive material.

First of all, you need to pay attention to the hydraulic properties of the web: permeability and density, and then to all the others.

In different cases of application of geotextiles, different types of it are required, and for each type of drainage - for the foundation and site, for closed and open drainage systems - there are particular indicators.

4 The choice of drainage geotextiles for arranging the foundation of the house

The main enemy of your home is water. It can cause subsidence, seep into the basement into the basement and go further up the capillaries of the wall material, cause the development of fungus, rotting of wooden parts. In order to avoid all these troubles, it is vitally important to make the so-called wall drainage - around the foundation. Drainage can be open or closed. You won't need it if your house is on sandy ground that freezes shallowly in winter.

Wall drainage around the foundation is constructed if there are basements and basements in the house

Geotextile for open foundation drainage

For open foundation drainage:

Mark out the places of the trenches.
The calculated slopes are verified.
Dig trenches and a pit under a collecting well, which is called a collector.
Around the foundation, an internal (to collect water) and an external, deeper (to drain water) trench are dug, which are connected by pipes or ditches, always at a slope.

Water from the soil, from rain and melted snow accumulates in the inner ditch, flows into the drainage ditch, flows through it into the collector, from where it is discharged either into the standard drainage ditch common for the site, or into the finished central sewerage system.

Open system is the easiest way to drain

Ditches near the house or in the blind area are closed with shields or gratings. It is cheaper and simpler than a closed drainage system and easier to clean. But the walls of the ditches can crumble and look unaesthetic.

Decorative grilles help protect the drainage ditch and give a more aesthetic appearance

Choosing a geotextile for this purpose is quite simple. One has only to take into account all of the above characteristics. And you will immediately notice several brands. For example, on the Terram 900 geotextile, which is very acceptable in terms of its qualities: density - 115 g / m2, ultimate tensile strength - 7.8 kN / m, elongation at break - 29%, puncture resistance - 1355 N, pore size - 160 microns, roll dimensions - 4.5 x 150 m, roll area - 675 m2, average price per square meter - 34 rubles.

Wall-mounted drainage

This is a complex and troublesome construction, but it will ideally protect the house from any moisture. Usually it is built if the house has basements and semi-basements, even during the construction of the foundation, around the base of the house, half a meter deeper than the lowest point of the foundation. At the corners, the pipes go to the inspection chambers. In the deepest place there is a collector that drains water from the site.

In this case, the mechanical load on the geotextile will be much higher. Therefore, we can recommend Terram 2000 geotextiles with higher characteristics: density - 215 g / m2, ultimate tensile strength - 14.5 kN / m, elongation at break - 30%, puncture resistance - 2750 N, pore size - 110 microns, dimensions roll - 4.5 x 100 m, roll area - 450 m2, average price per square meter - 55 rubles.

Trench type drainage

Such drainage is laid around the foundation at a distance of one and a half to three meters. He will cope with his work if the soil on your site consists of clay and loam and there are no basements and semi-basements. The depth of the pipes is the same as for wall drainage: half a meter below the foundation.

The difference between closed wall drainage and drainage at the site

In the case of trench type drainage, the load will be as great as in the previous case. Accordingly, we can also use Terram 2000 geotextiles.

5 Garden drainage system

Drainage in the garden area is necessary with close groundwater, waterlogging of the soil, which entails poor growth of garden plants. The principles of laying the system on the site practically do not differ from the principles of laying around the foundation, except for the depth. Likewise, drainage can be closed and open. Trenches 40 centimeters wide and of sufficient depth - up to half a meter - are dug along the markings. Slopes are made, pipes are brought to the wells and the collector.

Outdoor garden drainage is the simplest solution

The closed drain is covered with soil and plants can be planted on top.

Closed drainage scheme with geotextile

For such drainage, due to the open or shallow bedding, small loads on the geotextile are characteristic. Therefore, here you can save money and buy a thinner and more plastic geotextile Terram 500 with high hydraulic properties: density - 65 g / m2, ultimate tensile strength - 3 kN / m, elongation at break - 35%, puncture resistance - 525 N, pore size - 300 microns, roll dimensions - 4.5 x 150 m, roll area - 675 m2, average price per square meter - 30 rubles.

But there is even more practical and not inferior to Terram in all respects, domestic geotextile called "Dornit".

6 Geotextile "Dornit"

This brand of nonwoven geotextile has become very popular lately. It is created from polyester or polypropylene fiber in Russia, at the Road Research Institute (DorNII), based on French developments and is produced using a needle-punched and thermo-bonding method. Hence the name. Often dornit is called any needle-punched geotextile of different brands. It is quite durable, it copes well in Russian conditions, withstanding from 60 degrees of frost to plus one hundred - the boiling point of water, has a good filtration coefficient and sufficient strength. At the same time, it is cheaper than imported counterparts, and this is a good opportunity to save money. Therefore, it is safe to choose Dornit for absolutely all measures for drainage of the site, no matter what we start - drainage of the soil or foundation, in an open or closed way, choosing the appropriate modifications. Its characteristics are varied and cover all our needs.

Domestic geotextile "Dornit" is suitable for different types of drainage

Table: characteristics of modifications of "Dornit", suitable for different types of drainage of the personal plot

Position	Properties	units of measurement	Dornit modifications
			200	300	400	500	600
	Density	g / m2	200 ± 25	300 ± 35	400 ± 45	500 ± 55	600 ± 65
H	more 210	more 290	more 400	more 500	more 590
	Elongation at maximum load, Longitudinal Transverse	%	less 121 136	less 121 136	less 131 141	less 131 1410	less 131 141

	Transverse filtration coefficient	m / day	more 131	more 131	more 131	more 131	more 131

But, of course, even when using it, it is very important to comply with all laying rules, since Dornit, like any geotextile, with all its outstanding qualities, is very sensitive to mishandling.

7 Rules for laying geotextiles in open and closed ditches and trenches

When laying geotextiles, the following rules must be observed:

the ditch or trench must be dug extremely smoothly and accurately;
its bottom must be thoroughly cleaned of debris that can tear the geotextile;
geotextiles cannot stand ultraviolet radiation, losing strength, so you need to unpack and lay them out before laying;
it is better to cut it in advance, it will turn out more accurately;
when laying, geotextiles should not be pulled, but folds and wrinkling are also unacceptable;
it is necessary to sequentially fix each subsequent section during laying so that there are no distortions;
drainage should be backfilled into the ditch / trench immediately after laying the geotextile to avoid exposure to ultraviolet radiation;
the edges of the wrapping fabric must be at least 20 centimeters;
which side of the geotextile should be laid to the drainage, which side to the ground - there is a lot of controversy about this. Smooth or rough, knit or purl: there are specific guidelines for each brand. As a rule, the manufacturer places them on the packaging.

The ability to understand the large assortment of geotextiles produced by modern industry, knowing the nuances and peculiarities of its laying, it will be much easier to correctly design drainage, thereby saving the house or summer cottage from the destructive effect of water flows and the high humidity created by them.

Dornit is a durable non-woven fabric made from randomly oriented polypropylene or polyester threads, fastened together by a needle-punched method. In this method, serrated needles are pierced through the web to capture the fibers and tighten them.

There is also a thermally bonded needle-punched geotextile of the same name with subsequent heat treatment. With the method of thermal bonding, additional sheets are passed between the calenders with a simultaneous increase in temperature.

In road, oil and gas and civil construction, Dornit geotextile fabric ensures the reliability and durability of facilities. A huge advantage is the simplicity and efficiency of using geotextile not only in standard, but also in difficult conditions of wetlands or at low temperatures.

Dornit Nonwoven Geotextile Properties

Filtration

Due to its unique structure, it does not let soil particles into the pores of the web, preventing the possibility of siltation.

Reinforcing

Also, like the geogrid, it takes on the stresses of the soil mass and can partially perceive tensile stresses.

Drainage

Provides faster drainage in the plane of the web, thereby improving the operation of the drainage system.

Dividing

It is used as a separating layer, which excludes the penetration of materials of the top layer and base. In this case, the thickness of the top layer remains unchanged. So this is exactly the function that suits the foundation.

Geotextile Dornit and other geosynthetics are used for:

construction of drains for construction in the private and industrial sectors;
construction of railways and highways;
construction of tunnels, bridges and other complex engineering structures;
construction of underground structures;
arrangement of landfills for waste disposal;
when constructing slopes and embankments;
when protecting waterproofing of building foundations;
when arranging the roof;
in agriculture as a covering and protecting material against weeds.

In road, oil and gas and civil engineering, Dornit ensures the reliability and durability of facilities. A huge advantage is the simplicity and efficiency of using geotextile not only in standard, but also in difficult conditions of wetlands or at low temperatures. For example, polyethylene film 400 is able to withstand difficult weather conditions.

GEOTEX - mechanical hardened (needle-punched) nonwoven materials - are distinguished by sufficient strength, high deformability, protective properties, water permeability in the plane of the fabric and in the direction. Their main functions are drainage and protection, in some cases, when large deformations occur, reinforcement (for example, when laying a thin embankment of a temporary road in the basement).

In addition, polyethylene film 400 is often used in road construction. It has a high level of tensile strength and increased resistance to mechanical stress. Polyethylene film 400 is elastic and waterproof.

Dignity

Geotextile is a material known for its excellent resistance to aggressive chemicals. In addition, it perfectly tolerates even frost down to -60 and heating up to +100 degrees Celsius. Geofabric does not rot, it is not afraid of mold and mildew, which easily destroy wood and even some types of bricks. Plant roots, rodents and insects also cannot do anything with it.

It should also be noted its high mechanical strength and tear resistance. As a result, such a canvas is one of the most favorite materials of road builders, as it allows to achieve a high durability of the canvas.

Choice of density of geotextile fabric

This synthetic material is used in a variety of areas of land development. And for each specific purpose it is necessary to choose the right canvas. All types of this synthetics differ both in the method of manufacture and in physical properties, and most importantly in density.

The main principle in the selection: the deeper the covering material is laid, the more density it should have. Strength characteristics (elongation and elongation) also increase with this indicator. For example, if you are going to drain the soil in a garden plot, then the drainage system will not be laid very deeply, so in this case it will be quite enough to purchase geotextiles with a density of 150 or 200 g per sq. cm. It will quite cope with the pressure of a small layer of soil and perfectly fulfill all its functions: it will separate the various layers of the drainage system, preventing them from mixing, filtering and removing water in the required volume.

The owners of suburban areas are increasingly using wide rolls of geotextile when arranging the territory. What kind of material is this and for what purposes is it used? Let's try to figure it out. The nonwoven fabric, made from interwoven synthetic polymer fibers, has excellent quality characteristics: it is resistant to wear and decay. Due to the optimal combination of characteristics, geotextiles are conveniently used in many areas of human activity: in land management, in the field of construction, and landscape design.

Needle-punched geotextile- is created by pulling fastening threads through the warp with a serrated needle. It has excellent strength and excellent water permeability, which makes it widely used in drainage systems.
Thermally bonded geotextile- is made under the influence of heat treatment of the canvas, in which synthetic fibers are melted and more rigidly bonded to each other. It has a dense structure, high tensile strength, but lower filtration properties.

Thanks to a special manufacturing technology, geotextiles have a number of indisputable advantages, the main ones being:

Environmental friendliness. Geotextiles are not subject to decomposition into chemical constituents, thereby not harming human health and the environment.
Strength. Non-woven fabric is resistant to mechanical damage, puncture and tearing loads. The significant elongation of the material to break, which occurs due to the infinite length of the threads, practically excludes damage during installation.
Resistant to environmental influences. It does not melt, does not silt and does not rot, it is resistant to ultraviolet light, acids, alkalis and organic substances.
Ease of installation. The material is produced in the form of small and light rolls, which are convenient to transport and, if necessary, saw in half with a conventional hand saw. It is convenient to cut the material itself during use with a knife or scissors.
Cost effective. With excellent quality characteristics, the cost of geotextiles is quite low, due to which they are widely used both in industrial construction and for domestic needs when arranging suburban areas.

The possibilities of using the material amaze with the versatility of agrofibre. At the same time, with the release of new brands of geotextiles, the range of use of the material is constantly growing.

Geotextile is one of the environmentally friendly materials: it does not form any by-products under the influence of ultraviolet radiation

Thermally bonded geotextiles are used in road construction, agriculture, for strengthening the slopes and banks of water bodies

How can geotextiles be applied on the site?

Geotextile allows you to implement any ideas of geo-plastic transformation of the landscape on the site. Using non-woven material, you can create new design compositions, transforming the appearance of the site.

It is difficult to imagine a site without winding paths running deep into the garden. When planning their arrangement, you always want the result to be a beautiful and functional element of landscape design that will regularly serve for more than one season.

The use of agrofibre allows you to preserve the decorative effect and extend the service life. After all, even a device on a section of a small track requires a lot of trouble: excavation, backfilling of the underlying "cushion", laying of the coating itself. But during operation, when layers of gravel or sand gradually sink into the ground, depressions, bumps and irregularities begin to appear on the surface of the track.

A geotextile layer between the soil and the gravel bed allows for an even load distribution and prevents mixing of layers

It is convenient to use non-woven material when arranging sandy paths, gravel sites. The geotextile sandwiched between the soil and the backfill optimizes compaction so that the backfill will hardly penetrate the ground. This will significantly reduce the consumption of bulk material - and therefore the overall savings. In addition, the canvas will facilitate a rapid outflow of water and prevent the germination of weeds and grasses. In swampy and soft areas of the ground, non-woven material will completely perform the function of a durable reinforcement.

Option # 2 - waterproofing artificial reservoirs

When making a children's sandbox, so that the sand does not trample into the ground and does not mix with the ground, it is only necessary to cover the bottom of the pit with a layer of geotextile

Option # 4 - arrangement of foundations and retaining walls

The strength and durability of any building directly depends on the reliability of its foundation. If we talk about concrete types of foundations, then considerable damage is caused by capillary wetting by groundwater. Thermally bonded geotextiles help improve the waterproofing of a monolithic foundation.

When arranging foundations, geotextiles are used to separate fine-grained soil and gravel filling in order to prevent mixing of layers, and at the same time capillary wetting of walls

The material can simultaneously perform two functions: to separate layers and provide effective drainage, preventing prolonged contact of the surface of the concrete base with moisture.

Option # 5 - roof greening

By planting cultivated plants in the holes made in the canvas, you provide the plants with comfortable conditions for development, and you save yourself from laborious weeding

It is no secret that many ornamental plants are "finicky" by nature. They require special care, preferring a special soil composition, which is often different from the soil prevailing in the area.

It is possible to differentiate between different types of fertile soils by creating impromptu "pockets" for planting certain varieties, using the same geotextile

The creation of an artificial landscape on depleted soils requires the arrangement of a fertile layer, which, under the influence of natural conditions, is washed out into thinner layers. An additional layer of canvas will prevent contamination of infertile soils and their washout. Thanks to the non-woven fabric, plant roots will not grow into infertile soils.

Interseasonal night frosts also pose a great danger to plants. The material will also help out in the hot summer months, covering the delicate foliage from the scorching sun's rays.

With the help of agrofibre, aerial parts of plants can also be protected. To do this, during a cold snap, it is enough to cover them with a canvas.

Geotextile is a versatile material, the use of which does not require special skills. Its use greatly simplifies gardening and landscaping work.

M Many would like to know: geotextile - what it is and how it is used. It is a knitted or woven fabric that is characterized by significant strength. The material is created by weaving threads from different polymers at a certain angle. Fabrics are provided by manufacturers in rolls. Moreover, the density of matter can be different. A large number of positive qualities help geotextiles to be a versatile raw material.

The canvas is easy to use, as it is offered in ready-made rolls

Before buying geotextiles, you need to decide what it is and how it is used. It is a product consisting of woven and non-woven fabrics that are created from the components of polypropylene and polyesters.

Initially, this material was used only for drainage structures and the construction of construction projects, but then it began to be used for domestic and industrial purposes. Cloths are produced in different volumes and come in different types. The fabric is sold in rolls from 2 meters to 5.5 meters wide. The length can be from 40 to 150 meters.

Helpful information! In summer cottages, needle-punched material is often used, the structure of which includes small holes. Such agrofibre is used as a protective and covering material.

How is geotextile used in the construction of houses?

In the construction of houses, geotextiles are often used for the foundation. In order for the base under the building to be distinguished by its strength, a pillow or dump is used for the future foundation.

Geotextile protects the structure from the pressure of melt and groundwater and from soil deformation. It is also worth highlighting the following points:

the canvas prevents mixing of sand, soil and gravel;
the load on the base is evenly distributed;
the bearing capacity of the structure increases;
the base becomes more stable and stable.

Varieties of geotextiles

Having decided what geotextile is and how it is used, it is worth considering that this product may differ depending on the production technology. The following types of material are distinguished:

calendered geotextiles are made by bonding fibers using high temperatures, while the fabric has high strength properties, which minimizes the likelihood of breaks;

needle-punched type is made from propylene and polyester fibers, water can appear through the fabric in the longitudinal and transverse directions;

knitting and stitching material is made from special fibers of a certain length; for a strong connection of fibers, they are stitched with threads.

Knitting and stitched fabrics have a special structure

Helpful information! This material is made from polyester mass. On conveyor belts, bales of such a mass are torn off pieces of fibers, which are converted into separate threads under an air jet. Interestingly, 1 gram of such a thread is 3 km long. After the fluffing procedure, the threads are transformed into a cloth in a special machine.

Geotextile in the drainage system is used as a layer with filtration for perforated highways. Such a grid not only prevents siltation of the gravel bed.

Such material does not allow mixing of different layers of soil. For drainage systems, a product is selected with the following parameters:

density should be up to 150 g / m2.
monofilament needle-punched cloth is used;
filtration coefficient is about 130 m per day;
pressure strength should not be less than 400-500 N;
the width of the roll depends on a certain section of the filtration layer.

The blade is mounted without tension. For the overlap, allowances of 0.3-0.6 meters are left. When working on large areas, additional tissue fixation is required. After tucking the edges of the canvas, the soil is laid and compacted.

Helpful information! When choosing a material, you should give preference to products from trusted manufacturers. During installation, it should be borne in mind that the material is susceptible to the influence of sunlight, therefore, the canvas should be covered with soil as soon as possible.

Geotextile: technical characteristics

Geotextiles are affordable and versatile. In addition, the material has the following qualities:

resistance to oxidation process;
resistance to various aggressive influences;
resistance to fungal organisms;
inhibits the growth of weeds;
stops soil erosion;
has a filtering function;
helps to accelerate the drainage of water;
it has excellent reinforcing properties.

Geotextile is a type of technical fabric that is widely used in agriculture, construction, medicine and other industries. Initially, this material was used in road construction. Now geotextiles are used in the construction of drainage and erosion control structures. The material received high popularity in landscape works. For example, geotextile is often used for garden paths.

It is customary to call a geotextile a fabric made from various synthetic fibers. This material is highly liquid permeable, and at the same time retains even the smallest particles of soil.

The geotextile is resistant to both frost and heat. The temperature range at which the material retains its qualities varies from -60 to +110 degrees Celsius. Also, this material has high strength, it is able to withstand tensile strength up to 600 N. Geotextile is environmentally friendly and does not undergo organic decomposition. Due to these properties, people often use geotextiles for the garden.

Varieties of geotextiles

According to the manufacturing method, this material is usually divided into:

non-woven;
knitted;
woven.

The first type, in turn, has its own varieties. Nonwoven geotextile fabric is distinguished as simple, heat-set or thermally bonded.

Non-woven geotextile

Simple geotextile consists of It is made using harpoon needles, which entangle the raw materials and thereby create felt. Such material is capable of stretching. And therefore, it is wiser to use a similar geotextile for garden paths.

Heat-set (in other words, calendered) geotextiles are also needle-punched. But at the same time, he receives more hardening, which is achieved by rolling the rollers and blowing warm air. Such a canvas is the thinnest. But this property does not diminish its strength. The only drawback is that when heated, calendered geotextiles are less water-permeable.

In the manufacture of non-woven, the method of melting the raw mass is used. Its canvases have high filtration properties and strength.

Knitted geotextile

Its manufacturing method is reflected in the name. The looping method is used. The main advantage lies in the prices for knitted geofabric, the price of which is much lower than others. And the downside is that knitted geotextiles have a low breaking threshold. The material is about one to three millimeters thick. Its length varies from 100 to 350 meters, and its thickness is from 1.5 to 6 meters. The density of the fabric can reach 600 g / m 2. The last criterion determines the scope of this material.

Woven Geofabric

Woven geotextile consists of fibers that are tightly connected to each other. This manufacturing method significantly increases its strength. Based on the nature of the material from which the threads are made, the properties of the woven fabric change.

Woven geotextiles are widely used in the implementation of landscape projects. Most often, geotextiles are used for beds and for organizing drainage and embankments.

Benefits of geotextile

Geotextiles have many advantages, in addition to those that have been described for the above types. According to the reviews of summer residents, its positive aspects are as follows:

This material is safe to use because it does not emit any harmful substances.
Geotextiles do not rot and do not disintegrate in a living environment.
It has high strength, which allows the use of the material as a base for various purposes. Geotextiles are used in the country, as well as for medical purposes.
Easy to install.
Geotextiles are sold in rolls and, when used, can be easily cut with ordinary scissors.
Affordable price of geotextile (average cost - from 15 to 22 rubles per square meter).

The use of geotextile when planning a garden landscape

The material that can be safely used both in road construction and when planning the landscape of a garden plot is geotextile. The use of geotextile in the country has become commonplace. With the help of it, you can solve many of the problems that designers and gardeners have when planning the landscape and buildings for the garden.

Geotextiles can be used to insulate foundations and concrete slabs. It protects structures well from moisture ingress. Also, syntactic fibers will be able to save the lower parts of buildings from tree roots, which act destructively on them. It is customary to use geotextile in order to restrain moving soils, and in order to create the desired slope of the site.

It is an indispensable material for creating paths and lawns. When using geotextile fabric, the granite path will not be washed away by rainwater, and it will not be able to mix with the soil. Geotextiles are a great help against weeds when erecting a plot with lawn grass. Geofabric can be laid as a base for paving slabs. This material has proven itself well in agriculture, so it is great for arranging a garden, lawns.

Geotextile: use in the country for the arrangement of artificial reservoirs

Application of geotextile for growing garden trees and crops

This is the most common area of use for materials such as geotextiles. Application in the country can greatly facilitate the life of a gardener, because with the help of geotextile, you can grow seedlings, isolate the root system of garden plants, separate beds and flower beds, and much more. Geotextiles in the country are an irreplaceable assistant.

Geotextiles for garden beds began to be used in order to protect garden plants from weeds. If the bottom of the bed is covered with a layer of linen, the result is an excellent warming effect and excellent weed protection.

Pits designed for planting garden trees and shrubs can also be covered with geotextile, which will help solve the problem of root growth and protect them from pests.

Shelter of garden trees for the winter period can also be done with the help of geofabric canvases, which has shown itself well as a heater.

Summer residents use geotextiles when arranging their plots. The use in the country can be varied, for example, in order to retain moisture in the roots of trees and shrubs. To create such an effect, you need to cover the soil with a canvas and make small holes in it, into which shoots of garden crops are planted. In addition, it also solves the problem of weed control.

The main assistant to the gardener - geotextile

One can talk about the properties of this material for a very long time. But practice has already proved that the material that every person needs to have in the country and in the garden is geofabric, the price of which will also pleasantly surprise, because despite their excellent properties, geofabric canvases are available. Simplicity in working with the material will only add to the pleasant impressions about it. After all, its use does not require special skills in construction and does not require special equipment.

The modern world is very demanding on the characteristics of materials. Everyone is trying to choose something better, more innovative, reliable and natural. That is why manufacturers are increasingly moving away from synthetic products altogether, or offer excellent substitutes for natural substances. This applies to almost all spheres of life, from household, everyday life, and ending with construction products. Geotextile has become one of such modern materials, which combines the properties of natural products and high technology. Its main purpose is water filtration and soil separation. It is irreplaceable when working with any kind of soil, perfectly holds and strengthens slopes, and is also used in the construction of dams. The article will discuss the use of geotextiles.

Geotextiles are considered the best choice in cases where it is necessary to mount any hermetic underground structures and not worry that sharp stones can break through the protective layer. The product is used in the construction of buildings and houses, roads, landfills or other underground storage facilities, as well as various other structures.

There are several types of geotextiles according to the manufacturing method. It is worth examining in more detail the classification of this material and its main properties.

Geotextile fabric, types and characteristics

It is customary to call a geotextile a non-woven fabric made of synthetic fibers, which looks very much like a fabric. It is produced in large rolls, and is made from polypropylene or polyester fibers, which are pressed, forming a single structure. The product is distinguished by its low cost, but, at the same time, by excellent performance characteristics and a long service life.

The scope of application of the material is quite extensive, it is used in construction and in the furniture industry, in gardening and in households. Geotextile fabrics can be classified according to their area of application.

Drainage geotextile- it is used for the installation of a drainage system or for winding drainage pipes;

Furniture geotextile- used for interior upholstery of upholstered furniture and in the production of mattresses, as well as a protective layer during the transportation of furniture sets;
Garden Geotextile- in this capacity it is used to create greenhouses, since it perfectly protects from frost, as well as from direct sunlight, in addition, very often it is used to cover the ground around cultivated plants in order to reduce the number of weeds;
Construction geotextile- this variety is used for construction purposes, for waterproofing the foundation or basement of the house, paving slabs are laid on it, and also used in the construction of roads;
Packaging geotextile- is used as a packaging material for equipment, footwear, clothing and other substances and elements.

This classification does not give an idea of what the geotextile is made of. So, according to the manufacturing method, modern manufacturers offer several main types of geotextile material:

needle punched geotextile, which can be reinforced with geogrids or duplicated by geomat;

thermally bonded geotextile;
woven geotextile.

In Russia, most construction companies, and ordinary consumers, prefer to use thermally bonded geotextiles, while abroad they prefer to use needle-punched ones. This is due to the fact that the thermally bonded material, although it has high breaking loads, in fact, this characteristic does not guarantee long-term operation.

The thing is that such a canvas is not able to qualitatively filter water from soil containing clay or fine sand. Particles clog the structure of the product, and water does not penetrate inside, but erodes the upper layers of the soil. Needle-punched geotextiles have more elastic pores through which liquid passes freely, even if the material is used on clay soil.
This means that thermally bonded geotextiles can be used only in cases where the soil does not have fine particles, that is, as a drainage system, as well as to strengthen slopes. While needle-punched geotextile is a more versatile material, especially in cases of reinforcement with geogrids.
They also distinguish geotextiles made of polypropylene, which is the most durable, reliable and resistant to chemical attack. And made from polyester, which is considered not as resistant to chemicals.

And another type that deserves attention is mixed geotextile - it is made with the addition of recyclable materials (wool, cotton fiber, viscose) to the composition, has a low cost, but, however, does not differ in great reliability. This is one of the most natural and environmentally friendly geotextile materials, which, unfortunately, quickly breaks down during operation, since natural fibers rot from contact with water.

Needle-punched geomaterial

It can consist of both polypropylene fibers and polyester fibers, they are interconnected by a needle-punched method. That is, the fabric is obtained by pulling fibers with serrated needles through layers of special material. Thanks to this technology, the product perfectly permeates liquids, but only along and across.
In Russia, a material such as "Dornit" is produced by a similar method. It is based on polypropylene. It is resistant to mechanical stress and heavy loads, does not deform during operation and has excellent strength. It is most often used in road construction, landscaping and for strengthening slopes.

Heat-set geomaterial (non-woven geotextile)

It is obtained by bonding fibers at a high temperature. That is, the resulting fabric has increased strength, but is capable of passing water only in one direction - transverse. As a result, it is not recommended to use it for drainage or in the road sector, but is best used for weed control and for laying paving slabs.

In Russia, geotextiles are produced by Technonikol. The material is made mechanically and is bonded by heat treatment. The company positions its products as reliable and durable and proposes to use them to strengthen the foundation, in the construction of pipelines, roads, to improve drainage and as waterproofing.

Woven Geotextile

It is also called knitting and stitching, it also consists of polyester or propylene fibers, which in this version are stitched with threads. This is the least resistant type of product, since there is a risk of material tearing. As a result, the canvas becomes unusable, as it ceases to cope with the basic functions.

Advantages and characteristics of geotextiles

Geotextile material has many positive qualities:

versatile in application;
rot-resistant;
has high strength;

resistant to chemicals, both acids and alkalis;
has a long operational life and increases the service life of construction objects;
inhibits the growth of weeds;
prevents the development of soil erosion;
has filtering properties;
accelerates water drainage;
has a high resistance to tearing (capable of lengthening up to 45%)
has high elasticity;
reinforces building structures;
does not decompose and belongs to environmentally friendly materials);
has a low cost;
reduces the consumption of materials during the installation of structures;
easy to use and install.

When using geotextiles, the cost of maintaining structures is significantly reduced. Roads built on foundations such as peat, clay or other soils with high humidity may not survive even one season if they are not reinforced first. The crushed stone used in construction, due to the use of geotextile fabric, does not mix with weak bases and reliably keeps the highways from destruction and deformation.

Geotextiles are resistant to many external factors, including:

to punctures (you can not be afraid to lay the canvas even if there is a large accumulation of sharp stones);
to alkalis and acids (not affected by soils with any pH level);
to ultraviolet radiation (which is especially important in cases of roofing systems);
to bioorganisms (fungi, bacteria and others);
to groundwater.

When purchasing a product, you should pay attention to such parameters as:

density;
structure;
operational period.

So, the most popular material is considered to be made entirely of polypropylene. The service life of geopolitics can reach 100 years, no other similar material can compete with such durability.

Laying geotextiles

For the correct laying of the geotextile fabric, a certain sequence must be observed.

So, the first step will be the preparation of the foundation. That is, the surface is leveled, if necessary, the top layer of soil is removed a few centimeters, and the opened soil is compacted. If it is impossible to achieve the evenness of the existing layer, then it is recommended to fill up an even layer of sand and tamp it carefully.

The next step is to lay the geomaterial on a flat and clean surface. The rolls are rolled out on the base with an overlap of at least 25-35 cm. Such a measure is necessary for the material to efficiently cope with its main task. If it is not possible to achieve ideal smoothness of the base, then the overlap is made from 40 cm or more.
Next, you need to qualitatively connect the canvases. For this, special staples made of plastic or metal are used, you can also use the cold welding method. Staples take more time, so if quick installation is required, then it is better to use welding.
In order to qualitatively connect the material into a single canvas, the edges of the tape are heated with a special burner, and then a second sheet of geotextile is applied on top and the seam is pressed down for a short period. This is enough to securely fix the product.
The next step is to cover the geotextile with soil of the thickness required for each specific case. The soil is rolled, but not too heavy. Further, the rest of the materials are laid or the corresponding structures are erected, according to the required technologies.

Laying geotextiles is not difficult, it is important to choose the right material for a specific situation.

Before you buy geotextiles, you should remember that it can be different. Woven (obtained by interlacing threads at right angles), non-woven (obtained from polyester or propylene by needle-punching and thermal bonding of threads) and even knitted (the so-called geotricot, made by looping). The canvas has high strength and durability.

The material is used in many areas, especially where soil separation, reinforcement, filtration or as drainage are required. It is used in medicine, in road construction, in agriculture, in the construction of houses, in the manufacture of furniture and for packaging various substances.

The main properties include the fact that the product does not rot, does not change its qualities, even being in aggressive conditions, it is resistant to chemical reagents. The material perfectly permeates water, but does not silt up and does not clog up with soil particles. Remains reliable even at subzero temperatures (up to -60 degrees) and at high (up to +100 degrees). It is quite simple to lay geotextiles, and the strips can be fixed between themselves both with the help of special brackets, and by the method of cold welding.

Russian manufacturers offer their own version of the material, which is called "Dornit". It is produced in rolls, the width of which is 150 cm and up to 5.3 m, and the length is from 50 m to 150 m. The density of the product is different and varies from 90 to 800 g / m2. Canvases can be used in many objects, when constructing embankments, in landscape design, for drainage systems, in the construction of houses and roads. In terms of cost, it is the Russian material that is the most profitable for consumers.
