Today, a turnkey frame house in Vologda is ordered very often. If a crack has appeared in the wall of the house, this should not be negligent at all. After all, this is all due to the fact that a technological error was made during the erection of the foundation, or the wall of the building! But, having noticed such a nuisance and having figured out what the matter is in time, you can eliminate the problem before serious negative consequences begin.
Causes of cracks in the wall of the house, and what to do?
When the base of the building is done correctly, it will stand firmly despite the movement of the soil layers in different directions. But if cracks appear on the walls, then something is wrong with the foundation ...
In addition, there are other reasons due to which a crack may appear in the wall of a brick house, or panel one. For example, due to the fact that the design of the entire building is absolutely imperfect, or mistakes were made in the design, and maybe shortcomings in the process of construction work.
The first step is to say about the heterogeneity of the soil under the foundation. And the most interesting thing is that the density of the soil changes over time!
Well, before you repair cracks in the walls of the house, you need to understand where they came from.
How to understand the causes of cracks on the walls of houses
Be sure to record in this period what the temperature regime and the amount of precipitation are. It is advisable to keep this record for a whole year.
To clearly see what changes are taking place, you need to attach alabaster lumps on the crack, having previously soaked them. They will resemble plasticine in consistency. With an interval of 1 meter, it is necessary to install beacons along the entire crack. Well, by checking such marks at a certain interval, you will determine the reason:
- Naturally, if the mark cracks, or maybe falls off altogether, the crack grows. Based on the gap, you will draw conclusions how quickly the cracks increase.
- The mark may crack without leaving a gap, dynamic loads are applied to the wall, and there are no stresses or further discrepancies in the material.
- The mark is intact and there is no tension in the wall. This means that the crack appeared as a result of the fact that the shrinkage occurred one-time.
At the same time, it can be quite difficult to determine the causes of cracks on your own. Therefore, in many cases, it is still worth contacting professional craftsmen. After all, the matter is pretty serious.
By far the most dangerous case is when the crack grows. This means that either the foundation or the walls will be destroyed in any case. Of course, there is always a way out. For example, rebuild an emergency section of a house. But, if you noticed the problem in time, then you can be saved by such an option as a tight fitting.
In general, this is a fairly simple process:
- It is necessary to install steel corners along the outer corners, they should be with 10 cm shelves.
- Along the walls, on crutches, it is necessary to lay at least a couple of smooth reinforcement lines (above and below).
- Cut the threads on all the rods, and screw the nuts welded to the steel corners onto the reinforcement.
- On the side of the reinforcement rods, at a distance of 1 m, small rods should be welded to transmit rotation using an ordinary adjustable wrench.
- When the tightening is complete, the two need to twist the bars at the same time, while the tension must be gradually increased.
In this case, cracks can be avoided immediately and will not even be visible.
To strengthen the wall in problem areas, you must use:
- Reinforcement on the outside with steel or carbon fiber mesh.
- Anchor fittings, metal frames.
- Embedded reinforcing elements along the grooves.
- Injection method.
To close any crack, you need to completely clean it and expand it to 1.5 cm. Next, you need to anger the gap with a solution.
If cracks appear in the walls of a panel house, brick or in the foundation, it is imperative, and as soon as possible, to take the necessary measures to eliminate them. For example, you may need to strengthen the foundation. This can be done using screw piles and side or bottom grouting. Only after the construction expertise has been carried out, you will be able to determine ways to strengthen the foundation, and indeed, eliminate the problem of cracking.
10 photos of cracks in the wall of the house
Cracks in the walls of buildings can appear suddenly, and not only in old houses, but also in new buildings, panel and brick. This, of course, is not the norm, but you should not panic about this either. It is better to assess the scale and understand how dangerous the destruction is in order to determine how to eliminate it. All cracks are divided into two types:
- Passive- if cracking occurred at the same time, and does not go further, in this case, you can eliminate the defect yourself;
- Active- if a crack in the wall of the house expands or lengthens over time, there is a risk of the wall or building collapsing, in this case it is necessary to call specialists from the specialized service, who will make a decision.
Causes of cracks in the walls
There are dozens of reasons for the deformation of the building, and as a result, the manifestation of faults, serious, or "cobwebs". They are caused by various factors, but the most common is foundation problems. It is also the most dangerous and difficult, since in some cases you have to redo everything again, or somehow strengthen the foundation, and this is often not easy.
So, let's understand in detail why cracks appear on the walls in various buildings, is it worth worrying, and how to repair them.
Why are wall cracks so common in new homes?
Cracking of new buildings is a fairly common phenomenon. 9 out of 10 houses in a few years, due to shrinkage, may crack, but, as a rule, the cracks on the walls in a new house are small and passive, and after sealing, problems do not arise.
Experts do not recommend making major repairs in the first year and a half, and if your apartment is on the lower floors, and many people will be doing repairs on top, you should wait a little longer. The fact is that all the neighbors from above will "add" weight to the structure with plaster and decoration, which means that the house will shrink even more noticeably.
Small cracks on the walls in a new house seem to be not scary, but they can lead to tiles falling off, wallpaper deformation and similar problems. Better to wait with finishing than to redo it all over again. In addition, the small "cobweb" under the wallpaper will not be noticeable, but it is advisable to close it up as soon as it appears.
Why is there a crack in the wall of a house that no longer shrinks?
In more habitable and seemingly strong houses, cracks can appear completely unexpectedly, and usually they are the ones that most frighten residents. The reasons in this case can be very different.
- Violation of construction technology, in which the bandaging of the brick wall was incorrectly performed. For many years everything is in order, and then a rift appears, which is also difficult to close.
- Violation of the technology of laying communications... It happens that first a house is erected, and then communications are brought in, as a result of which the foundation is dug in - this is one of the common reasons for horizontal cracks in the wall.
- The foundation may settle and by itself, for example, due to incorrectly calculated load or insufficiently competent design without specialized calculations. Owners of private houses who do not conduct geodetic surveys, do not study the features of the soil, and choose the wrong type of foundation often suffer from this. The reasons for cracks in the walls can also be attributed to improperly laid sand under the foundation, or underground waters unaccounted for during construction.
Why did the crack start on the wall of the old house?
In older homes that have stood for decades without problems, sudden cracking can occur due to new construction in the vicinity, excavation of a foundation pit nearby, vibrations when piling or re-laying a road. Problems often arise due to unsuccessful, ill-conceived redevelopment, when the new owner demolishes the load-bearing supports, or illegal construction of basements and underground floors, as a result of which the load is shifted and the foundation suffers. A crack in the outer wall of a house also occurs due to the fact that the solution can crumble over time, and if floors were added to the house, or it was lengthened, the problem can become critical.
The problem with a crack in the load-bearing wall at the base of the building
Another common answer to the question, why do cracks appear on the walls? - ill-conceived redevelopment, especially on the basement and first floors. This happens when residential apartments are transferred to non-residential stock, arranging shops or service establishments, and at the same time they touch the load-bearing walls. The load on the rest turns out to be more, and the house collapses from the inside, and the tenants of the upper floors are usually the first to notice the problem.
It is usually impossible to resolve the issue with the owners of the premises, so if cracks appear on the inner walls, and at the same time below there are offices or retail premises, it is necessary to contact the relevant authorities to check the condition of the building.
Types of cracks in the walls
You can try to determine the cause of cracking yourself, focusing on the direction of the fault: vertical, horizontal, in the corner. In brick walls, the direction may be broken, but the general trend is usually seen.
- Vertical cracks... Thermal deformation can occur in the middle of a building if there is a problem with expansion joints. In places of supports and beams - due to overloading of walls (this is very dangerous). The reason may also be a fragile foundation, as a result of which one part of the building settles in a different way.
- Horizontal cracks on the wall of the house can be caused by the subsidence of the foundation in its central part, and the ingress of moisture into the walls and base. They are less dangerous for the building as a whole, but it is necessary to check the quality of the insulation. The causes of horizontal cracks in the wall are usually less dangerous, and the building collapses more slowly than with vertical ones. But it is also more difficult to fasten the structure together, it may require serious measures to correct the situation.
- In the corner of the wall destruction can occur due to flooding of the foundation, as often happens when moisture from the roof drips into this corner. Microcracks are generally harmless, although more difficult to repair.
In any case, if there is a crack in the wall of the house, you should call specialists who will determine the cause and scale of the problem.
What cracks in the walls of the house are dangerous
A fine web of cracks is generally not dangerous, no matter where it is located. But in any case, it is better to control this process.
To determine the danger, that is, the future divergence of the wall, various beacons are used. In domestic conditions, to control wall cracks inside the house, you can use paper or plaster, which are superimposed on the crack at different ends, possibly in the middle. If the line is broken, you will need to apply beacons to all areas. Be sure to write down the date of installation next to it.
It happens that it is not possible to install the lighthouse on the outer wall on your own if the fault occurs on high floors. In addition, gypsum and paper simply cannot withstand weather conditions, and a gypsum beacon is generally capable of cracking from temperature extremes. There are other options for lighthouses, which are available from specialized specialists, and are suitable for external control.
If, within 8-12 months, the crack on the outer wall of the house or inside it has not changed or increased, it can be considered passive, stable, and repaired.
If beacon deformed or collapsed, be sure to call specialists, this means that the process is active, and measures must be taken.
Crack in the wall of the house: what to do and how to repair
There are many ways to solve the problem, and the choice of a particular one depends on the characteristics of the fault and its development. Keep in mind: if a large crack in the wall quickly diverges and the lighthouses collapse, you are unlikely to cope on your own, you may have to fasten the house with metal plates, raise the structure to adjust the foundation, strengthen it, put supports instead of load-bearing walls, etc.
Crack in the outer wall
Clean small stable cracks from plaster and finish, apply a deep penetration primer, and close the entire crack with a filler mesh so that it reliably overlaps the edges. A putty is applied on top, better reinforced, since it will withstand temperature changes and the effects of weather conditions.
Cracks in the brick are repaired with a metal plaster mesh, which is bolted in place. A layer of mortar (cement + sand) is applied to it.
A large crack in the wall is filled with foam, while first you need to expand and clean it, perhaps rinse with water and dry it so that more solution gets inside. Various cylinder attachments are available so that even tricky bends can be repaired.
Fractures in concrete are also cleaned out, blown out with polyurethane foam and sealed with a cement-sand mixture.
Crack in the corner of the wall
Especially often it occurs at the joints of the slabs, and if this is the corner of the house, then blowing can be felt from it. It is either sealed with polyurethane foam and then plastered, or a system of metal plates is used, the whole house can be pulled together, if the problem is serious, or part of it.
In multi-storey buildings, you have to do everything from the inside, or order insulation along with sealing cracks. If the fault is large, it must be deepened and cleaned with high quality, preferably with a construction vacuum cleaner, or at least with a brush, and the foam is applied to the not yet dried primer.
Cracked walls inside the house
Small cobweb, which was formed as a result shrinkage of new buildings, you can easily cover up: you will need a putty mesh and a deep penetration primer. A primer is applied to the cleaned wall with the removed coating, covered with a net, and sealed with putty. Then, after drying, the surface can be wiped and painted, or pasted over with wallpaper. Better to wait a bit to make sure the problem doesn't recur.
If there is a crack along the wall concrete house, it needs to be expanded, creating angles at 45 degrees, and primed well. Sealing is carried out either with concrete mortar or with a sealant. The sealant fits better, since it is a little "rubbery", which means that future movements will be compensated and the crack will not expand. Do not use a silicone-based sealant, as nothing sticks to it, and then it will be difficult to paint over or wallpaper. A crack in the wall of a house can also be repaired with any cement-based mixtures, such as tile glue or plaster. You can use an emulsion to which cement is added, or there is an even more budgetary option - PVA glue and cement. You can apply such a mixture with a spatula, and for the sealant, special pistols are used to help squeeze it out of the tube. The remains of the mixture are removed with a spatula flush with the wall.
Cracks in a plasterboard wall usually appear due to excess moisture, dampness, or improper installation. If flooding occurs, the sheets need to be changed; in other cases, you can save the situation with the help of a special putty for drywall, or use acrylic (sold in the same tubes as sealant). Another option is to stick the fiberglass, it is more reliable, although more expensive and more labor-intensive. All these methods can be used only in the case of high-quality fastening of the drywall sheet to the wall, if it does not stagger, otherwise you need to change the sheet itself.
Vertical and horizontal cracks on the wall brick houses sealed in various ways, depending on the depth and nature of the fault. In any case, if the crack is active, it makes no sense to repair it using simple methods, since it will continue to grow. Repairs only make sense when the fault has stopped and is stable for several months. Small cracks on the inner walls of bricks are sealed with cement mortar, but if the gap is more than 7-10 mm, you need to expand it with a hammer (for better adhesion of the mortar) and repaired with a mixture of cement and sand. A crack larger than 10 mm requires professional intervention, regardless of whether it expands or not.
Crack in the wall of the house: what to do if the wall is load-bearing?
It is possible to close the faults on your own only if the crack is small and does not expand. In this case, the same technologies are used as for repairing small damages in a brick wall. But it is important to understand that a break in the load-bearing wall can lead to the collapse of the entire building, so it is worth contacting specialists. They will check the condition of the building and find out why the cracks in the wall appeared at all: perhaps the neighbors have redeveloped somewhere, or something happened in the basement of the building, and it urgently needs to be strengthened, pumped out water, raised the roof and reduced the load.
Crack in the load-bearing wall is always very dangerous, so it is not worth delaying with it, especially if it is active and expanding. You can already identify a dangerous rift in a day or two by placing the simplest plaster or paper beacon, and checking its safety and absence of deformation. In any case, it is better to play it safe.
Through cracks in the walls
The most dangerous type of cracking in which a building can be declared emergency. There are many reasons for this phenomenon, but most often - problems with the foundation or an extension, or construction work ongoing nearby.
To seal through cracks in the walls, a lime-cement mortar is used, if the fault is large, fragments of brick can be added to it. Formwork may be needed to fix the mortar until it hardens completely.
Sometimes tightening with metal plates made of durable material is used, and at least three strips are needed, sometimes more. Fix them with bolts and dowels. After fixation, a specialist decision is required - if a crack appears in the wall of the house, then the problem is already quite serious. From the inside, the break can be sealed with polyurethane foam, but in any case, the cause must be eliminated.
Output
If there is a crack in the wall of the house - rate it the crack is growing, visually (in the case of cracks, "cobwebs") or using a beacon. Various materials and technologies are used to seal up different types of walls, but if the crack is growing or large in itself, it is better to consult with specialists. Minor repairs can be performed independently, but only if the fault is stable and there are no prerequisites to believe that further cracks in the walls of buildings can lead to emergency.

All cracks appearing on the foundation of the house indicate that the base of the building needs to be strengthened or repaired. But in order to do this with your own hands, you need to know about the reasons for the destruction of the base, as well as how exactly restoration work should be carried out.
Why are cracks dangerous?
If the foundation of the building is cracked, you must immediately begin work to restore it. If this is not done, after a while, due to the skewing of the house, the doors and windows will start to jam. If the house is made of bricks, the crack can spread to the wall, causing the entire structure to collapse. That is why it is necessary to begin work on strengthening the foundation as soon as possible.
Before starting restoration work, it is worth determining the type of crack. To do this, it is enough to clean it from dust and rinse it with water. After that, you need to install a beacon on the fault. The date of consolidation is applied to it. This is necessary to determine the rate of destruction of the base. If the lighthouse remains intact within two weeks, the crack can simply be repaired with concrete. If the lighthouse breaks, it is necessary to begin work to strengthen the base.
Usually cracks begin to appear in winter or spring, since it is at this time that an improperly created foundation begins to rise or settle unevenly. It is worth remembering that the foundation can burst due to many reasons, so you need to think about this problem even at the design stage of the house.
Causes of faults
Before starting the restoration work, it is necessary to determine the reason due to which the destruction began. If these actions are neglected, even after repair, the base will gradually collapse. The causes of destruction can be divided into several groups:
- Technological. An example is the creation of the foundation of a house with violations of the reinforcement or installation of formwork. Also, mistakes can be attributed to the choice of the wrong grade of concrete. The laying of the foundation above the water table is also considered a technological error.
- Operational. Such mistakes are made already in the process of using the constructed structure. For example - an increase in the load on the foundation as a result of the creation of the second floor. Also, a violation is an increase in humidity in the basement or poor-quality installation of a drainage system near the house.
- Structural. An example is the compilation of incorrect calculations during the design of a structure. Often, the foundation begins to collapse ahead of time due to the fact that geological studies were not carried out before the start of construction.
Important! In order not to face the described problem before building a house, it is necessary to accurately calculate the load on the foundation.
Crack types
Cracks in the foundation of a wooden house, which can occur on the foundation, are divided into several types:
- Hairy. Such cracks are hardly noticeable and have a thickness of no more than 3 mm. Their presence speaks only of a change in the outer layer of the base. Such flaws can be corrected quite easily.
- Horizontal. Such defects do not affect the integrity of the foundation.
- Shrinkage cracks. Such defects occur when the rules for creating a foundation are violated.
- Vertical. It is these cracks that are a sign that the foundation needs repair. Often they appear under the influence of groundwater on the base or due to heaving of the soil.
How to fix the problem
If you notice that the foundation of the house is cracked, you need to start strengthening it as soon as possible. Such work is carried out as follows:
- first, with the help of a jack, the sagging parts of the base are raised to the design level;
- after that, pits are drilled, the diameter of which ranges from 20 to 40 cm;
- the resulting void is filled with liquid glass, cement laitance or hot bitumen.
This reduces the permeability of the soil, which will make the soil more stable. The described strengthening method can only be used with the use of special equipment, therefore, professional builders must be hired for such work.
Strengthening the foundation of a stone house
The main task of repairing the base of a house is to stop the process of settling the structure. therefore, it is impossible to dig under the foundation without securing it. A method of strengthening is often used, in which a reinforcing concrete belt is erected from all sides. Such work is carried out as follows:
- A trench is dug along the strip base of the house, the width of which is approximately 45 cm. During such work, the sole of the foundation must not be exposed.
- After that, the foundation is cleaned of dirt and dust. In this case, all cracks must be opened with a spatula.
- Then the falling off parts of the old foundation are removed.
- In the next step, the concrete surface is treated with a primer. It is worth remembering that you need to choose formulations of deep penetration.
- After that, holes are drilled in the foundation. The distance between them should be about 60 cm.
- Anchors are driven into the created holes, which are subsequently welded to the reinforcement cage. The diameter of the reinforcement should be approximately 12 mm.
- At the last stage, the concrete mixture is poured into the created trench. In order for the concrete solution to be evenly distributed over the trench, it is necessary to use a construction vibrator. It also helps to fill cracks in the old foundation. If this stage of work is neglected, voids can remain in the concrete, which will subsequently cause the foundation to collapse.
Backfilling of the soil occurs only after the concrete has completely solidified. If the cracks are not caused by subsidence or deformation of the foundation, they can be repaired with mortar and plastered.
It is worth remembering that if the work is carried out with an error, the foundation will quickly begin to collapse, even if there are additional reinforcing elements of the structure.
Repair of the base of a house made of wood
The cracked foundation of a wooden house can be strengthened quite simply, since such structures can be lifted with a jack and installed on temporary supports. But it is worth remembering that if the lower logs are rotten, the structure cannot be lifted.
If the crowns are unreliable, rotten areas are cut out in them, after which the house is raised. After that, you can restore the foundation in one of the common ways. Often, owners of country houses install a concrete bandage around the base. You can also dig under the base and pour concrete pillars. This will make the foundation resistant to significant loads.
It is worth remembering that before raising the house, it is necessary to disassemble part of the roof in the place where it connects to the chimney. To carry out such work, it is better to invite professional builders.
Reinforcement with piles
In some cases, it is not possible to increase the density of the soil under the structure. In such a situation, it is necessary to strengthen the base with piles:
- If the house is wooden, the whole structure is raised on temporary supports, after which a bunch of heads with a grillage occurs. After that, the structure is lowered onto a new foundation.
- In the case when it is necessary to strengthen the base without raising the house, "bulls" are used. They are piles that are driven obliquely from different sides of the corner. Beams are welded onto the heads of these elements, which will serve as a support for the structure.
When using piles, it is worth remembering that their length must be sufficient so that they abut against solid ground.
Monolithic slab repair
Monolithic foundations are destroyed quite rarely, but under certain conditions it is possible. If a serious crack appears on such a base, it can only be replaced with a new plate. No way will help stop the destruction of a monolithic foundation if it is already beginning to deform.
Conclusion
If it is impossible to completely replace the foundation for some reason, the walls are strengthened and the old sections of the slab are removed. In these places, concrete solution is poured, which helps to temporarily preserve the integrity of the structure. you can also install concrete blocks or piles as supports.
After years of operation, even the sturdiest and strongest houses can give up slack. In many cases, this manifests itself in the appearance of cracks in the walls and ceiling. The streaks may be microscopic at first, but will inevitably enlarge over time. If not repaired, defects can lead to damage inside and outside the building. As a result, the wall decoration will completely deteriorate. Today we will tell you why cracks can appear and which ones to fix.
The reason for the appearance of cracks
It may seem that the only cause of cracks is wall wear, but this is not entirely true. Deformation is influenced by a number of factors. Cracks can appear at a shallow depth and width of the foundation, excessive pressure on the ground, which can lead to its mobility. This often happens with older buildings.
Problems can also arise if substandard materials such as gravel or concrete were used to fill the foundation. For such structures, the grade of concrete must be at least M 200. The above factors are associated with a violation of construction technology, but this is not the only problem. The house is able to sink due to the rise of groundwater, the slope of the site, the destruction of the foundation body or soil heterogeneity.
Before reinforcement, you need to prime with a deep penetration compound
Another factor is the quality of the materials from which the walls are built, how resistant it is to external influences. Cracks can appear due to swelling, vibration or shrinkage, too busy street traffic. Severe weather can also cause mother-in-law to appear on the walls.
Eliminating cracks with reinforced mesh
If your walls are sagging, the most suitable repair method is mesh reinforcement. It consists in stretching special plastering or painting nets based on fiberglass on the plaster or putty layer. sold with mesh sizes 2x2 mm, and plaster - from 5x5 mm to 45x45 mm. When plastering or painting, the mesh should not be completely immersed in a thick layer of mortar.
The mesh absorbs tensile stress and prevents cracking. The material can stretch up to 3%, but if the building shrinks or moves a lot, the mesh will do nothing. Putty or plaster will peel off the surface and hang on the mesh itself.
Repair of cracks in the walls (Video)
Mesh reinforcement is used in certain cases. For example, at the corner joints of walls made of different materials: one wall is made of gypsum board, and the other is made of plaster. If your walls are about 5 years old, the entire surface may crack due to shrinkage of the concrete. In this case, it is not necessary to reinforce the entire surface, but you can do it in the corners.
Such brickwork must be disassembled and replaced with a new one. Fresh bricks are laid with the so-called "brick castle". It is better to use pieces of reinforcement that cover the gap as part of the masonry. Bricks are dismantled from top to bottom. If the masonry cannot be disassembled, the gap is sealed with cement mortar. Depending on the length of the gap, T-shaped metal anchors are driven into it, which are fixed with dowels on both sides of the wall. Cracks in brick walls can also be repaired. After the material has solidified, it is cut to a depth of 2 cm. The cavity is sealed with cement mortar.
How to fix cracks in concrete walls?
If you have cracks on a concrete wall, some preparatory steps are required before starting the main work. First, the opening in the wall needs to be widened. Then the surface is thoroughly cleaned of dust and plaster residues. Then apply a primer and wet the surface to be treated. There are several ways to repair a concrete wall.
The first one involves blowing out the crack with polyurethane foam and puttying. Polyurethane foam is sold in cylinders. This foam is excellent for installation, because it increases 2-3 times in volume after application. The material can be used not only in working with concrete structures, but also with wood and metal.
In the second case, the gap is filled with cement mortar. After removing foreign objects, it is washed and filled with a solution. For best results, use an expanding compound. After treatment, the crack is moistened for 2-3 days in a row. Polyvinyl acetate can be added to the cement solution.
Cracks can be finished well when filled with resin. They begin to inject it immediately after the preparation of the wall. Attention! Be sure to wear gloves and goggles to protect yourself from the harmful effects of the resin. Cracks can also be repaired with special concrete restoration compounds.
conclusions
Any appearance of cracks should give a signal that the walls need to be urgently repaired. Do not delay with this and, if possible, try to do the repair yourself. This is not as difficult as it seems at first glance.
Due to the movement of soil layers, the entire structure tilts, then in one direction, then in the other direction. But the structure itself is solid, at the expense of the good.
In the event that a crack has appeared in the wall of the house, this may mean that the foundation is doing its job very poorly, but there are many more reasons why cracks can appear even without destroying the foundation.
If the supporting soils do not evenly accept the load, the tape will deform more than the walls of the building can withstand.
It's easy to do:
If the markers remain intact or the cracks expand or contract, then this means that the foundation is doing its job well, and there was stress in the wall materials that splashed out in the form of cracks.
To strengthen the wall in the emergency area, use:
- Reinforcement with carbon fiber or steel mesh, outside;
- Metal frames or anchors;
- Reinforcing elements that are laid along the strobes;
- The injection method is used.
So before starting construction, consider all the nuances. Well, if you still have trouble, then after reading this article you will know what to do.
