The wall of the house burst what to do. How to strengthen the walls of a brick house

The article reveals mandatory tips, without which it is impossible to make a high-quality screed, which would prevent the destruction of walls in the future

Screed as a mandatory element of damage prevention

Sometimes it happens that self-built houses can cause some troubles over time, one of them is the appearance of cracks in the building. The appearance of cracks promises not only the destruction of plaster and decorations on the walls of the house. On the one hand, there really is an aesthetic moment, but on the other hand, the presence of cracks in the walls of the house can become very dangerous, so you need to screed the walls of the house in time. Outside, we see only a crack, and the reason is hidden inside and means the presence of destruction in the foundation. We'll try to figure it out how to make wall screed at home to prevent destruction of the house. Even those who have just moved to private house, because the problem can overtake unexpectedly. And then it will be too late to wonder how to restore the house .
How to pull off walls you can read on the relevant resources and do it yourself. For example, during the construction phase, concrete and cement-sand screeds must be laid on a layer of sound and heat insulation.
Before how to pull a house with concrete or cement mortar remember a few rules:

  1. Each room (or plane) must be poured with concrete (cement) entirely and at a time. It is not allowed to fill in two approaches (that is, you cannot fill in half of the room today, half tomorrow)
  2. The mortar of cement or concrete should be used within 1.5 hours (it also cannot be left for the next time, so before pulling the house down, calculate how much mortar you will need.
  3. The material will ripen best in a humid environment, so when you finish pouring, cover the plane with a film and keep it that way for up to 7 days, but not less than 3 days. On about the third day, it will be necessary to fill the screed with sawdust or sand and fill it with water. Then the screed will not dry quickly, will not crack and will mature qualitatively. After this procedure, you need to allow the solution to dry.

Tips on how to pull walls together are best thought out, analyzed as to whether they are suitable for the materials used and checked by professionals. Then you won't have any problems.
Anyone knows how to make a wall screed at home professional builder, so you can safely entrust this procedure to your workers.
It depends on how you will make the screed. what does a screed at home look like. You can make a wall screed using the described method, using fittings or a special liquid fraction. You can read about what a screed at home made by professionals looks like on the forums.

Building a house using bricks is one of the most common options today.

Whatever expensive materials were not purchased for the construction of the structure, after a certain period of time cracks may appear in the walls, which indicates the presence of a negative process occurring in the foundation. Repair work to eliminate the defect is important to carry out as quickly as possible. Otherwise, the building may warp, internal surfaces deform, and the foundation will completely crumble.

If the wall cracked brick house, before proceeding to repair work it is necessary to understand the reasons for the appearance of such a defect. Experts identify the following points that led to destructive consequences:

  • proximity ground water can lead to undermining of the foundation, resulting in deformation of the base and subsidence. In addition, constant fluctuations temperature regime negatively affect the binders that make up the foundation;
  • shrinkage of the house - natural process. Depending on the composition of the soil, a soil shift can take place over several years;
  • when pouring the foundation was broken technological process or low-grade material is used.

liquidation


In fact, the process is quite laborious and requires special attention. In most cases, the defect appears due to deformation of the base. If a crack in the foundation of a brick house is obvious, then you will need to perform the following measures:

  • along the wall where there is a crack, a trench of certain overall dimensions is dug near the foundation;
  • the area with a crack is embroidered with utmost care and caution (the hole expands slightly);
  • to understand how to strengthen the foundation of a brick house, you need to drill holes for the reinforcement bar in the cleared area. Welding can be used if necessary. Thus, a kind of connecting link is created;
  • then formwork is installed and a new foundation layer is poured. Leave the trench filled with mortar until completely dry;
  • after at least 28 days, compaction can be carried out on the site and a blind area can be built.

Repair work


By strengthening the foundation in the future, you can prevent the formation of new cracks, as well as stop the expansion of existing ones. Moreover, this concerns the growth of the defect both in length and in width. If the wall of a brick house has already burst, then in addition to strengthening the foundation, a simple procedure should be carried out, according to the results of which it will become obvious whether the growth of the split has stopped. It is enough to stick peculiar beacons made of paper on the cracks in the walls of a brick house. If after a certain period of time the stickers remain intact, then you can safely proceed to repair work. To do this, do the following:

  • minor cracks in brickwork, the causes of which have been established, and the width does not exceed 5 mm, can be covered with a conventional cement mortar. Beforehand, the edges of the recess must be carefully beaten, construction debris removed, and the surface moistened with water for better adhesion to the cement mixture;
  • if the width of the gap reaches 10 mm, then it is sealed with a cement-sand mortar prepared in a ratio of 1: 3.


When a brick house cracked, and the width of the target exceeds the average size, then you should more thoroughly approach this task. Having eliminated the causes of cracks in the brickwork in the first place, emergency measures can be taken to eliminate surface defects, restoring its integrity.

  • Before reinforcing brick walls, it is necessary to disassemble the damaged masonry fragment. The disassembly procedure is carried out from the top row. All bricks that are damaged or not tightly held are subject to removal.
  • Fixing cracks in brickwork occurs by laying new bricks on the cleaned part of the wall. Many may ask how to strengthen the walls of a brick house so that history does not repeat itself in the future. It is enough to include reinforcement, metal corners or strips in the process of making new masonry. In addition, the masonry must end with a lock.
  • Restoring the knots of a brick house, you need to use steel strips. Such linings are fastened with bolts or other elements to give strength and reliability to the structure.
  • If a brick wall cracked, and it is impossible to sample a brick, then the damaged area must be filled with a mixture of crushed stone and cement mortar. Stepping back from the edge of the crack 20-30 cm, a “T”-shaped anchor is fastened, after which the gap is connected with a strip of metal.
  • How to strengthen a brick wall if the depth of the gap is large enough? Very simple. Holes must be drilled along the entire length of the crack, the step between which can vary within 20-25 cm. A pipe is inserted into the holes obtained, with the help of which the hole is filled with cement mortar. Nozzles on the pipe can be used those that are most suitable for filling holes of various diameters.
  • Strengthening cracks in masonry can also be done using mounting foam. After the foam has completely solidified, the excess is cut off, and the surface is treated with cement mortar.


Both vertical and horizontal cracks in the brickwork that have gone through are eliminated in the event of a complex of restoration works. After it was possible to strengthen the brick wall from the outside, you can proceed to repair measures inside the building.

  • The section of the wall where there are cracks is thoroughly cleaned of dirt and plaster. The crack is maximally moistened inside.
  • Before you strengthen the old brick wall inside, you should fill the existing gaps with a solution of fine gravel and cement.
  • window section in brick wall carefully inspected for damage. It may be necessary to remove this one with the subsequent installation of a more advanced one, for example, plastic.
  • Before pulling off the walls of a brick house, you need to carefully examine the entire surface of the wall and fill in all the gaps. Only then are metal overlays mounted, which are fixed with any fastener (bolts, anchors, dowels).
  • wall plastered by special means. After the surface has completely dried, you can safely proceed to facing work indoors. Read more about that at the link.

It is essential to carry out such work. Indeed, through the cracks in the foundation and the wall, cold air flows into the room can penetrate, which is simply not acceptable. After sealing the cracks, you can additionally place a layer thermal insulation material to create a kind of barrier to the cold. This, in turn, will significantly save money on paying for energy carriers, which is very important at the present time. It is also worth paying attention to the option.

More on the topic:

The described problem resembles a typical case bearing capacity changes due to changes in hydrogeological conditions. Bearing capacity the foundation of the house was not enough, and after the first crack it began to actively collapse at an increasing rate (now much less forces are needed to develop destruction). The reinforcement in the foundation and masonry (armor belts) is most likely absent, and after the appearance of a crack, there is nothing to hold the walls of further destruction.

This problem is fixable. In any case, you should check with the designer-calculator, giving him the opportunity examine the structure of the building in detail. Surely the cost of restoring the integrity of the house will be incomparable with the cost of building a new similar structure or the risk of its sudden catastrophic destruction.

The procedure for restoration work

1. Provide an opportunity for specialists examine the house in detail, including excavation of pits along the foundations, punching walls for taking samples and studying their structure.

2. If necessary, perform foundation strengthening. There are many ways and techniques, so without studying the real situation it is difficult to advise anything. If, however, there is a recommendation from a specialist to strengthen the foundation with an increase in its depth, you should first strengthen the house according to the recommendations below, and then return to strengthening.

3. Need inject cracks and tighten the building. For this you need:

3.1. Clear the plaster along the cracks to the brick. The width of the cleared strip is at least 5 cm.

3.2. Wash out the cracks water from a pressurized hose. Remove loose pieces of old mortar from cracks and any other debris that can be removed.

3.3. Glue fiberglass over cracks on the epoxy glue. After 20-30 cm, leave holes with a diameter of 8 mm.

3.4.fill the cracks repair staff. Normal tile adhesive gives good results. The solution should be diluted to the state of liquid sour cream. As an injector, a syringe gun is also used to seal the seams of panels or a conventional silicone gun with an empty bottle of some kind of sealant. Fill cracks from the bottom up from the outside and inside walls at the same time to the hole. Then you need to close it with a stopper (you can use plasticine), move the injector higher and repeat the operation. In this case, it would be preferable to use a professional injector.


3.5. pull down the building strands of smooth reinforcing steel according to this scheme.

Puffs should be placed under the ceiling of the 2nd floor and above the floor of the 1st floor. Due to the high coefficient of thermal expansion of steel, they should only be placed inside the house. The range of rolled metal in the figure is indicated approximately, based on the fact that the building is brick and has maximum size 8x8 m. The process of tightening the screws should be started at the maximum high temperature inside the building. Tighten the screws evenly throughout the building. Upon completion of this work weld nuts with electric welding, color metal parts, plaster or concrete strands and nuts with plates on the facade, perform final finishing.

General Tips
During the construction of a house or overhaul most are faced with the question of the need to reinforce the screed during its formation. Someone decides to save money and is content with only a concrete screed, while someone, in order to give ultimate strength, reinforces all surfaces, so to speak, “for centuries”. It is worth understanding the need to apply reinforcement of the floor screed and the ways in which you can make reinforcement with your own hands.
The construction of the screed varies into several types, depending on the intended purpose and the place of its formation. So, there may be the following options for screeds:
Rough screed on the ground or base plate;
Floor screed on floor slabs;
Screed for leveling, self-leveling floor;
Screed with laying a layer of sound and heat insulation;
It makes sense to reinforce the floor screed in cases where a rough screed is formed and when creating a multi-layer screed with thermal insulation. In these cases, it is necessary for the reason that the screed is not made on a monolithic and fixed base and is subjected to tensile and bending forces. Also, reinforcement can be performed in order to save concrete, if it is required, according to calculations, to form too thick layer concrete.
Reinforcement of the screed can be done in several ways. You can choose the right one based on design and operational requirements and only after the reinforcement has been calculated. It is quite difficult to perform independent calculations based on the requirements of SNiP and GOSTs, and you can miss a lot of nuances and features, so it is better to contact a design organization for this.
Now consider the materials and structures that can be used to reinforce floors:
reinforcement frame;
wire mesh;
welded mesh with a cell of 5-20 cm;
polymer mesh, fiberglass reinforcing mesh;
fiber additives in the composition of the solution.
In any case, the reinforcement technology is performed according to a specific construction scheme.
Any reinforcing material must be distributed in the thickness of the mortar used for the screed. To do this, it is distributed over the surface strictly before pouring on special supports (does not apply only to additives in the solution in the form of fiber).

The composition and structure of the reinforcement should not interfere with the distribution of the solution under its layer.
The reinforcement material must have good adhesion to the mortar. To do this, it should not be contaminated with oily substances or opened with paint or other substances.
Reinforcement must be completely sunk into the mortar layer to prevent corrosion, decay, oxidation under the influence of moisture or air.

The formation of frame reinforcement is advisable only in cases where the foundation of the house, that is, the foundation and the floor screed, are complete system to hold the building. Also in cases where it is justified by calculations and the need in view of the unreliability of the supporting soils. At the same time, reinforced concrete structures with a total thickness of at least 10 cm and a reinforcing frame height of at least 5 cm. Method 1: frame (monolithic) reinforcement
You can build a reinforcing frame right on the spot, using reinforcement for this. In construction, rebar is used in sizes from 6 to 40 mm, depending on the design requirements and the required strength. In private construction, reinforcement with a diameter of 10 mm and 20 mm is most often used.
You can “knit” a frame from reinforcement using steel wire 2-3 mm. At the same time, a base grid is formed with a cell of the required size within 10-20 cm and everything is connected with the mounting of lifting ribs. On the ribs is formed upper layer reinforcing frame in the form of the same mesh as on the bottom layer. It is best to use solid pieces of reinforcement along the length and width. If you want to use trimmings and shorter pieces, then the reinforcement is extended overlapping with at least half a meter overlapping each other. Next, the screed is poured. This option is also called monolithic reinforcement, because the result is actually an integral and inseparable reinforced concrete slab. Video: knitting reinforcing mesh
Rebar clamps can serve as an alternative to knitting or welding
Often, when forming a reinforcing frame, welding is used. For independent work this option is only suitable for those who have available welding machine and enough skills to weld thin rods and wires. By the way, in industrial construction, only professional welders who have already proven themselves are allowed to do such work, because this type of work requires attention and accuracy. If the welding technology is violated, the reinforcement and wire at the joints often become thinner, which negates all the benefits of the frame.

During the reinforcement of a concrete floor, it is often required to bend the reinforcement to form the frame. This operation should only be performed using mechanical means without heating, as is customary among some unconscious masters. With any heating, the metal changes its structure and can easily burst. Method 2: wire mesh reinforcement
More simple option reinforcement is a mesh made up of wire. This method allows you to strengthen the screed up to 80 mm thick. It can be used when forming a multi-layer subfloor on a soil base or as a reinforcing screed on floor slabs in areas that are particularly subject to stress, such as kitchens, bathrooms, hallways or garages. The reinforcing mesh should also be distributed in the thickness of the solution, which will fill the floor. In fact, the scheme of reinforcing mesh in place is similar to the first stage of performing wireframe reinforcement. As a result, the grid is installed at a height of 2-3 cm and poured with a solution.
The mesh can be either twisted wire or welded. It should be borne in mind that welding is only advisable when using wire and fittings with a diameter of 6 mm or more. If a heat-insulating layer and waterproofing are located under the screed layer, then the binding to the walls is not made and the mesh with its edges should be 3-5 cm from the walls.

It is enough to lay them in strips over the entire surface of the floor with visits of 1-2 cells on top of each other and tying them with wire. At a cost, this option is only slightly more expensive than using wire for independent formation grids. On the other hand, much less time is spent and the reliability of the mesh itself is somewhat higher.
Method 3: reinforcement with polymer meshes
This is one of the most simple ways reinforcement. It is mainly used not to specifically strengthen the screed structure, but to prevent cracking of concrete or cement mortar during complete drying and minor deformations. Often the mesh is placed directly on the base, especially if it is a film located on a bulk cushion or a layer of thermal insulation to prevent cracks from forming on the underside of the screed.

Polymer meshes have found the widest application in the process of reinforcing self-leveling floors. This is due to the simplicity of its distribution and the peculiarities of the technology of self-leveling floors. During their formation, the main desire is aimed at reducing the volume of the spent solution and the thickness of the resulting layer, and reinforcement options using wire rod, and even more so reinforcement, are not suitable for this. Method 4: Use Additives in Solution
fiberglass
AT modern construction fiber is gaining more and more popularity. These are polymer fibers with a thickness of about 15 microns. By adding them to cement-sand mortar or concrete, you can strengthen the screed layer and prevent the formation of microcracks during the drying process.
Even if the conditions for proper drying and setting of concrete are somewhat violated, the risk of microcracks in concrete is significantly reduced. However, one cannot rely on microfiber for the sake of wanting to circumvent the requirements and technological aspects of concrete floor formation.

General Tips
When using any method of reinforcement, options for adding microfiber or plasticizers to concrete can be used. It is only necessary to follow the instructions for their use and dosage.
The process of forming a screed or self-leveling floors contains many nuances and steps, in addition to reinforcement, which must be taken into account and performed in order to obtain a reliable base for the floor as a result. The most complete and complex is the process of forming and reinforcing the floor on the ground. At the same time, up to concrete screed and reinforcement, layers of sand, gravel, thermal insulation and waterproofing are being installed. Violation of the technology for building such a "pie" will negate any efforts to reinforce.
