Today, many methods are offered to stop the appearance of cracks in buildings, one of which includes screeding the house against cracks, which is performed using various materials. Cracks are the cause for subsequent destruction of the structure and lead to emergency situation, which requires immediate resolution of this problem.

Screeding a house with reinforcement

To perform this type of work, certain skills and abilities in welding are required, and you should also correctly calculate required amount reinforcement and its diameter. These parameters are determined depending on the area of ​​the entire building and the damaged areas.

You can carry out these activities yourself, but it is better to contact a specialized organization. The company's professional staff also take into account the degree of destruction of the building, the number of floors, the type of foundation and type of roof, as well as the characteristics of the soil and territory.

In some cases, in places where the walls are not particularly damaged, it is recommended to lay out new masonry, and in areas with an increased degree of destruction, tighten them using reinforced and more durable reinforcement.

Required materials for screeding with reinforcement

For screeding with reinforcement, the following materials and tools are required, which include:

• Fittings;
• Hairpins;

The technology of screeding with reinforcement is not complicated and consists of the following: special corners are attached to the corners of the house, into which studs are threaded and washers and nuts are screwed on. The house is held together using nuts, which are regularly tightened depending on the condition of the building.

Characteristics of fittings

Reinforcement is elements that are connected to each other through concrete and are reinforced concrete beams that carry tensile stress. It is also used to impart increased strength and rigidity. different designs. Its components can be rigid (various angles, channels and rolled I-beams) and flexible (grids, frames and profile rods).

There are several ways to connect reinforcement to concrete, which include:

• Interaction by friction;
• By shift method;
• Bonding during concreting of a reinforcement element;
• Connection at the electrochemical level;
• Compression with concrete after shrinkage.

Classification of fittings

Today, reinforcement has the following classification depending on various characteristics.

Depending on the area of ​​use:

• Strained;
• Unstressed.

Depending on the intended purpose:

• Working;
• Assembly;
• Anchor;
• Constructive.

Depending on the location in the structure:

• Transverse;
• Longitudinal.

Main types of house damage

Screeding a house against cracks is carried out as a result of the following reasons that lead to a violation of the integrity of the house.

And these include the following:

• Camber;
• Blockage;
• Extension department.

Features and description of the collapse of the structure

Mostly, the collapse of the house leads to the formation of cracks in the upper corners of the openings, and the walls are deformed by waves or separated by the entire surface.

This type of destruction can be complete or partial. Complete implies a change in the state of everyone load-bearing walls structures, and partial - only some partitions.

Easy house collapse

The main signs of such destruction include cracks in half the corners of openings, deformation of the heads of walls up to one third of the height when in good condition foundation.

The reason for the occurrence of such processes may be the significant weight of the roof, the construction of an additional floor, as well as the lack of a reinforcing belt. In order to eliminate this, it is necessary to use a steel clip on the corner supports.

Rods run along the façade external walls, and to complete the work you will need steel angles, a pipe, studs and nuts, a steel rod, subsequent welding and painting.

Average camber

The main signs of such destruction are the same reasons that are observed with slight collapse, but with a probability of up to 80%.

The reasons for the appearance may be insufficient reinforcing belt, significant overload and lack of connection between walls and corners during the initial construction of the building.

IN in this case It is recommended to screed along the entire perimeter of the house in three layers of steel belts to ensure better and more reliable fixation of the walls. In this case, the steel circle can be replaced with a strip, and the welding seams must be of excellent quality.

Strong collapse

The main signs are the appearance of noticeable cracks in the walls and foundation of the building, as well as a combination of other reasons that are characteristic of light and medium destruction. The cause of the appearance may be destruction of the foundation of the house.

To avoid complete destruction of the building, continuous support and corner clips, as well as a retaining belt of the foundation, are used.

Laying reinforced concrete along the entire length of the base is used.

Description of the collapsed house

A blockage involves the collapse of walls inside a house, which can be complete or partial. In all cases they are fulfilled welding work in the middle of the premises, which, as a rule, requires major repairs in all rooms of the building.

Complete blockage is characterized by blockage of three walls to varying degrees. The reasons may be impaired house construction technology and insufficient reinforcing belt. To eliminate this, a rigid steel frame with a through fastening is used.

Watch the video:

A partial collapse is characterized by the obstruction of two walls, which may be caused by negative impact moisture or atmospheric precipitation. For repairs, a partial holder is used according to the principle of continuous installation.

Annex department

In most cases, a combined separation of the house extension occurs. The main sign is a crack at the joint with the main house or at an internal corner.

The main reasons for such destruction are the lack of connection of the extension to the house during its construction, as well as a poor foundation and possible overload of the additional room.

The screed of a house from cracks is eliminated by a set of measures, including the use of through, semi-through, anchor clips and supports. In this case, supports can be located along the entire perimeter of the foundation or clogged in individual places.

When cracks appear in brick walls, the home owner has no time for jokes. His task is to strengthen the structure. In general, many people prefer to limit themselves to sealing gaps, but it is worth understanding that without repairing main reason there is not much benefit from this.

Below we will talk about a method for screeding walls that have begun to crack. brick house.

The extension has moved away

The main factor in the divergence of masonry is the deformation of the foundation. All the rest are nothing more than consequences.

When cracks occur at the junction of the extension with the main house (and this is the problem that people encounter most often), the connection between the walls erected in different time. There are several ways you can help here.

If the fault no longer expands, it is sufficient:

• clean from dust and poorly adhering solution;
• prime well;
• fill with fresh cement to the full depth.

Usually this “treatment” lasts for several years, but later the crack will definitely manifest itself.

The second option is much more reliable. This is where the screed is made. To do this, metal corners (up to 100 by 100 mm) are installed in the corners of the extension, and thick steel strips with holes are installed inside the house. Then they are connected by rods with threads at the ends and tightened with nuts.

Bad connection

If the brick was not laid according to correct scheme, then the connection between the rows turns out to be quite weak. This, however, does not mean that the building will necessarily crack; however, if the foundation is deformed, then a fracture will form precisely in the weak spot. In such a situation, the entire defective wall is screeded.

Other technology violations

First of all, they are evidenced by the rupture of the masonry clearly along the seam. In this case, the blocks always remain intact. More often this problem is caused by:

• poor wetting of brick surfaces;
• insufficient pressing to the solution;
• improper preparation of the masonry mixture (not enough cement).

If errors were made when calculating the foundation or the house turned out to be heavier than planned, then cracks often form in the corners of the building. This, however, is also caused by the lack of additional reinforcement for this part of the structure.

Here, one screed will not be enough, since it does not fix the main problem– we will have to further strengthen the foundation. You shouldn't give up on this if you want to continue to live in the house for many years.

A responsible homeowner should have the house screeded just in case for preventive purposes immediately after construction is completed. With this approach, the occurrence of cracks is reduced to zero.

If the trouble in question did happen to a mansion in which people already live, then this method will not only slow down, but also stop the destruction process.

First of all, prepare:

• 4 wide (100 by 100 millimeters) corners, whose length corresponds to the height of the walls;
• reinforcement or round rod with a cross-section of at least 16 mm and a length equal to two perimeters of the building;
• up to one and a half meters of thick-walled ½ inch pipe;
• threaded studs with a diameter of 16 mm;
• 16 washers and nuts each.

First of all, in external plaster cut through the fines, remove it from the corners. If this is not done, then subsequently it will not be possible to disguise the metal ties.

The remaining work is performed in this order:

• 150 mm sections of pipe are welded to the corners on both sides;
• blanks are installed on the corners of the house;
• cuttings of studs (20 cm) are connected to the reinforcement by welding;
• the latter is inserted into the pipe and secured with nuts.

If you use a smooth rod (circle), then you can cut a thread on it with a die, then there is no need for studs.

To tighten the nuts more tightly, you can heat the reinforcement with an autogen - the metal will expand, and then cool and contract.

When the house is subsequently planned to be insulated with foam plastic or lined with siding, the studs are simply welded overlapping to the rods - such a connection will be much more reliable, and the unattractive appearance will be hidden by the finishing coating of the facade.

In other cases, the reinforcement is connected to the studs end-to-end. The welding site will need to be further strengthened. The same pipe is best suited for this. Sections up to 120 mm long are made from it. They are cut lengthwise and welded over the joint.

The nuts should be tightened in several stages, with an interval of a year.

When choosing materials, do not try to save money - a corner that is too thin will not be able to ensure high-quality fastening of the walls. There is also little benefit from being too narrow.

Sealing cracks

Once the screeds have been installed, you can begin to seal the gaps. Small ones (from 1 to 5 millimeters) are filled with facade putty. Large ones (from 10 mm) require the use cement mortar prepared in the usual way.

Very large cracks are pre-filled with mounting foam - it will penetrate deeply and provide good thermal insulation. After it dries, the wall is leveled with plaster.

Remember, in order to prevent the crack from appearing again in the future, it is necessary to properly prepare it before sealing. In particular, it is dusted as thoroughly as possible with a vacuum cleaner or blown with a compressor. Before applying the plaster, the surfaces are moistened with water using a sprayer or, at worst, a broom.

It is not advisable to use reinforcing mesh in this situation - they help only when it comes to shallow cracks that form only on the surface of putty and other similar materials.

This video will help you understand the process better:

What to do if cracks appear in the wall of the house– the problem, naturally, is relevant not only for residents of Saratov and Engels? A common phenomenon, especially for brick houses. The foundation of the house has burst, a corner has come off, cracks have appeared in the walls - don’t wait for your house or cottage to fall apart - take action.

Before covering cracks with cement mortar, you need to strengthen the house. This is called tightening the house from cracks.

A metal screed for a house in Saratov is the installation of a kind of metal frame on top of the building so that the house does not “diverge” further. But simply physical labor is not enough here; to perform house screed work in Saratov, you need the theoretical knowledge and skills of an experienced welder.

Our specialist comes out to assess the complexity of screeding a house in Saratov.

So, when a crack appears on the wall, under no circumstances should you cover it up or foam it with foam. First of all, you need to pull down a house, and only then cover it up. This is done in order to mind reduce cracks when contraction.

The next stage that you need to pay attention to is the foundation, you need to determine the place where it has sunk, it can also be strengthened but by a different method.

Another important point is blind area of ​​the house.If the blind area has burst and is moving away from the base or foundation, it needs to be replaced around the perimeter of the house, with reinforcement reinforced in the foundation.

Could a crack really break everything?

Of course, it can, if you don’t attach importance to it right away. Cracks in the wall can be either harmless to the integrity or turn the home into a pile of stone and dust, which can take not only a lot of valuable things, but also human lives.

You see, a crack formed in the wall (in most cases) is only the tip of a huge iceberg, which confidently moves towards the foundation, destroying it too. It makes no sense to explain why a foundation split is dangerous, since everyone knows what this will ultimately lead to.

If we reason correctly, then it is not the crack that leads to the foundation, but on the contrary, it comes from it, since only a serious physical impact can start a split from the center and lead to two or more directions. There is no other way to create such an injury to the building.

You may encounter other reasons if your building was built from bricks that were laid with gross errors. They often appear as a result of saving money on auxiliary materials that serve as the prevention of these diseases.

Why is all this happening?

There may be more than one reason, since the condition of the foundation is influenced by many factors. Having identified the most basic ones, we are ready to present them to you:

• displacement of earthen rocks due to seismic activity of the area. In the countries of the post-Soviet space, the phenomenon is quite rare, but, nevertheless, in some areas at the foot of the mountains such cases do occur. Even the Crimean Mountains, not to mention the Caucasus, are no exception, making themselves felt from time to time with minor earthquakes. They are imperceptible to humans, but can quite noticeably affect the foundations of buildings;
• climatic conditions are also not left aside. Nature may not have bad weather, but the foundation doesn’t think so. Due to excessive moisture or, conversely, its lack, the earth, clay, sand or their synthesis can sag from time to time, thereby affecting the position of the foundation, lowering one of its parts, forming cracks that will force you to tighten the walls;


• Trees could grow next to your house, the power of whose roots can easily pierce the foundation. In my memory, next to my parents’ house, literally three or four meters from the wall on the side backyard, the previous owners planted a nut. By the time we moved there, it was already a little more than ten meters in height, and its roots were close to the building itself. After 3 years of our living there with outside A crack about three centimeters wide and more than two meters long opened, which was very elegantly hidden by the old owners who had moved far away using putty and whitewash. The reason for this turned out to be the ill-fated nut. The natural solution to this problem was to cut down the tree, which also entailed certain losses. The first is permission to cut down a tree, since it is impossible to engage in amateur activities in this matter. The second was a broken roof from falling branches, because it was incredibly difficult to direct them in the right direction. And the third is a crack in the foundation, which later had to be strengthened with reinforcement;
• an initially incorrect design or construction site can also cause splits to form in the walls of the house.
  significant cracks up to one millimeter wide are not normal, but acceptable for new buildings, so if you have one, do not be alarmed ahead of time. Almost all scientists and builders claim that any building takes about five years to sit normally on the surface of the earth due to its enormous weight. You should not completely ignore such moments. Any crack that forms must be monitored so that it does not begin to increase in size. If this happens, then this is a sign of improper construction, and you need to contact the developer to get the necessary advice or even help. If you notice that cracks have appeared in your home, then you urgently need to contact specialists in this field, because only they can provide you with qualified support.

How to deal with cracks in walls yourself

Any distortion in the foundation and, therefore, in the walls requires immediate repair. Many of us may be faced with the problem of insufficient funding and the search for a more budget-friendly and independent restoration of the integrity of your home.

Naturally, there is a solution, and, purely theoretically, it will not require a colossal amount of financial investments and physical strength, since closing a crack is a very real task for any person.

Yes, it is with the help of an artificial screed made of reinforcement that you can strengthen the foundation and prevent your house from splitting in half, as if the world had again begun to divide into continents.

What is a screed and what does it consist of?

Screed - only decision, which will help you stop or cut off the possibility of complete destruction of the house. Why suspend? You see, if the building was erected with errors in the construction itself or in an unsuitable place, then the process of destruction cannot be stopped. Whatever you do, you will only delay the outcome of the event. Naturally, this is if the problem is in the foundation. If you find that the cause of the split was the wall itself (it can be made of brick or wood), then everything will be a little simpler.

If you have expressed a desire to repair the breakdown yourself, then you will need certain skills, without which it will be a little difficult:

• In order to save a lot of money and not buy an already welded screed, you can limit yourself to purchasing fittings and electrodes, and then independently welding the required size of reinforced mesh. So, the first thing is welding and the skills to use it.
• fittings Something without which you will not be able to make a screed either for the foundation of the house or for its brick or wooden components. It will be exploited different ways, but her presence is mandatory. Why? The reinforcement has the necessary ratio of size and strength to ensure that the structure itself is as comfortable, reliable and, if necessary, aesthetically pleasing as possible;


• to strengthen the lower part of the foundation of the house you will need a large amount concrete mortar, the method of application of which I will tell you a little later;
• Piles will come in handy when shaping the area that needs to be filled with concrete. And then you will need to give it the required form. Don't skimp on them, as low-quality wood may break and force you to redo the whole job. If you are not interested in the aesthetic beauty of the foundation, and you do not want to spend extra money on logs, think about how much money you will throw away on excess concrete mortar, which will certainly spread around the house for a distance of about half a meter.

Let's move on to the practical part of installing the screed on the base of the house

We've read a lot of stories and theories, but now let's look at how to do it all in practice. The very first thing you will need to do is arm yourself with a shovel and, if possible, equip several of your friends or hired workers with them to speed up the process. Start digging at the place where the rift originates. Go deeper to a depth of about half a meter. It is possible that more depth will be required, given that it depends on the height of the building, its number of floors and the load it creates. You can find out the depth of the foundation from the house construction plan.

It is necessary to excavate not only the place where the breakdown occurred, but also along the house at a distance of one and a half, or better yet, two meters. This distance is also determined situationally and individually for each building. Why do you need a big ditch? If you strengthen a small part, the split will repeat much faster than you can cook dinner and raise a glass to a job well done.

The second stage will be the construction of a reinforced mesh. Reinforced mesh It consists of reinforcement rods welded in such a way as to create a network with squares, the side of which can be at least ten centimeters. If you reduce this distance, the solution may simply split in two without fixing the required area.

An increase in this indicator leads to the fact that the reinforcement process does not in any way contribute to an increase in strength, but only creates the appearance of work performed. If financial issue does not play a big role, then it is better to make a double grid, that is, build it in two levels. This will require more concrete but will provide additional strength.

A small life hack: It is quite possible that you do not have enough funds to purchase required quantity reinforcement for screed. If time does not allow you to wait, then you can replace it with ordinary concrete pillar. Yes, it will not provide the same level of strength, but it will serve quite confidently as a temporary structure. And if we take into account that there is nothing more permanent than something temporary, we get an excellent alternative.

Having built the grid, you need to firmly fix it to the foundation of the house. Drill holes and install mesh. You don’t have to rush to seal up the resulting cavities, because in the next step everything will become more clear. This ends the third stage.

Fourth - installation of piles. In some cases they are not needed, but if you have made a serious dig at the house, they will come in handy. Install the piles and wooden fencing in order to proceed to the next step.

Fill everything with concrete. Very important point is precisely that you should under no circumstances fill the screed by manually puttingtying the cavity between the mesh and the house. This process only involves pouring concrete mortar. Otherwise, all the work will be done in vain and will not show any results. The building will continue to deform.

After you have done everything we indicated above, wait until the concrete hardens. This will take up to one week, depending on climatic conditions your area.

What to do if trouble occurs on the masonry?

Tightening the walls of a brick house is much easier, but it is unlikely to lead to a complete solution to the problem.

The reason for the formation of holes between the bricks, if the base of the building is not affected, is the incorrect laying of the stone itself. The right decision there will be demolition of the wall and rebuilding it, but if you cannot afford to tear it down and rebuild everything again, then there is also a solution. Let's look at it step by step:

1. Determine the place where the fault began. It was on this row that a mistake was made in the construction.
2. Install threaded holders on one and the other side of the wall that will hold the reinforcement that creates tension. Do not forget that the thread should also be on the reinforced rod.
3. Pass the reinforcement through the holders and secure it. Pull the rod as tight as possible to create tension. Do not overdo it, as you may tear out the outermost brick.

If the split in the wall is small, then you can use ordinary dowels along the entire crack.

There is a lot of information on the Internet about how to properly tighten walls. If you enter into Google the query “the wall has come off, how to steal a video,” then a host of assistants will instantly come running to your aid. Here, for example, is a video about what to do if a similar situation occurs with a house made of timber:

But don't forget that the most best help provided by qualified specialists. Don't skimp on your home if you don't want to be left without it.

Very often, owners of private houses, especially brick ones, are faced with the problem of cracks appearing on the walls. This happens due to shrinkage of the foundation, deformation of the soil structure, and strong currents. groundwater or due to improper use of the building.

The method of wall repair will depend on the reason that led to the appearance of cracks. The most difficult and difficult to repair is a defect that arose as a result of poor-quality installation of the foundation. In this case, in addition to repairing the wall, it is necessary to carry out work to eliminate foundation defects and only then begin to remove cracks. Otherwise, if you neglect foundation repairs, all other work will be pointless.

Most often, cracks in the walls of a brick house appear above the openings of doors or windows. If they are small, then they can be filled with a special liquid fraction. This is done in such a way that it fills all the empty space. If this method does not help, then you need to strengthen the window and door lintels.

In cases where such measures do not help, you need to think about how to tighten the wall of a brick house. Such measures are used to eliminate large cracks. To eliminate the vertical gap, holes are drilled through in the brick, into which metal fasteners are then inserted. These fasteners are steel beams that are tightened with special pins. When the damage to the masonry is very significant, the wall opening should be completely dismantled and re-laid.

If the damage to the building is located in a horizontal position, in order to properly eliminate the fault, you must use metal plates. Such plates must be installed in the gap in such a way that a seam connection is obtained. This will allow for reliable strengthening of the house structure. This must be done, since such horizontal damage can lead to the wall completely moving.

When damaged areas of a structure have both horizontal and vertical directions, steel staples must be used. To attach them, holes are punched in the wall. And the final fastening is done with steel strips.

When repairing masonry, you should remember that the faster a crack is detected, the more effectively it can be eliminated. This is due to the fact that the longer she is left unattended, the bigger size she becomes. In the future, this will lead to the fact that the house cannot be repaired and it will completely collapse.

Screeding a house with reinforcement

To perform this type of work, certain skills and abilities in welding are required, and you should also correctly calculate the required amount of reinforcement and its diameter. These parameters are determined depending on the area of ​​the entire building and the damaged areas.

You can carry out these activities yourself, but it is better to contact a specialized organization.

And these include the following:

• Camber;

Features and description of the collapse of the structure

Mostly, the collapse of the house leads to the formation of cracks in the upper corners of the openings, and the walls are deformed by waves or separated by the entire surface.

This type of destruction can be complete or partial. Complete involves changing the condition of all load-bearing walls of the structure, and partial - only some partitions.

Easy house collapse

The main signs of such destruction include cracks in half the corners of the openings, deformation of the heads of walls up to one third of the height in the normal state of the foundation.

The reason for the occurrence of such processes may be the significant weight of the roof, the construction of an additional floor, as well as the lack of a reinforcing belt. In order to eliminate this, it is necessary to use a steel clip on the corner supports.

The rods run along the facade of the external walls, and to complete the work you will need steel corners, a pipe, studs and nuts, a steel rod, subsequent welding and painting.

Average camber

The main signs of such destruction are the same reasons that are observed with slight collapse, but with a probability of up to 80%.

The reasons for the appearance may be insufficient reinforcing belt, significant overload and lack of connection between walls and corners during the initial construction of the building.

In this case, it is recommended to screed along the entire perimeter of the house in three layers of steel belts to ensure better and more reliable fixation of the walls. In this case, the steel circle can be replaced with a strip, and the welding seams must be of excellent quality.

Strong collapse

The main signs are the appearance of noticeable cracks in the walls and foundation of the building, as well as a combination of other reasons that are characteristic of light and medium destruction. The cause of the appearance may be destruction of the foundation of the house.

To avoid complete destruction of the building, continuous support and corner clips, as well as a retaining belt of the foundation, are used.

To strengthen the foundation, reinforced concrete is laid along the entire length of the base.

Description of the collapsed house

A blockage involves the collapse of walls inside a house, which can be complete or partial. In all cases, welding work is performed in the middle of the premises, which, as a rule, requires major repairs in all rooms of the building.

A crack in a building is not only unsightly, but also dangerous. After all, a crack on the outside is only a consequence, and the cause is deeper - these are cracks in the foundation itself, and this is a direct path to the failure of the house and its further destruction. Often there is neither the desire nor the ability to erect a new building, so a way to preserve an existing structure was invented - screeding the house with reinforcement. But before you start repairing, you need to understand all the nuances. Screeding a house, the price of the work depends on its complexity and, of course, the cost of materials. The builder, who this work will fulfill. Screeding a private house with corners can be done independently, which will lead to significant savings. Buy all the required materials in advance, but also keep in mind that the foundation that needs to be strengthened requires certain skills.

Screeding a house with reinforcement must be done with fairly serious knowledge of welding and calculations required diameter fittings. Its size is selected depending on the degree of destruction, the number of storeys of the house and its size. But experts also take into account the roof, its shape and covering, the type of foundation, soil and even the region of residence. The average person may not take all these nuances into account, and the cost of screeding a house with reinforcement, which is not so high, is a serious matter and should be handled by professionals.

If a crack has appeared in some small areas of the house, then it is advisable to lay them out again before the walls of the house are tied with reinforcement. Particularly loaded areas can be tightened with thicker, reinforced reinforcement. To screed a house with reinforcement, not so much is needed building materials: the reinforcement itself of the required diameter, studs corresponding to the size and cross-section of the reinforcement, washers and nuts.

The technology for installing the reinforcement is quite simple - stops for the rod are welded on the corners, the level should be different for each wall, this is done in order to avoid the studs and nuts from getting stuck. The resulting corners are attached to the corners of the house, then studs are threaded through the stops, washers are put on them, and nuts are screwed on. The house is held together using nuts.

When screeding a house with reinforcement, you should not immediately tighten the nuts too much, do it gradually, especially since periodically, about once every six months, the nuts need to be re-tightened. The cost of a corner screed for a house can be found on the Internet in order to navigate its ranges.

After the work was done, I stayed final stage– primer and painting. House screed, the prices of which differ depending on the chosen fittings, will be in any case economical option for you. After all, cracked walls are much easier to repair than to rebuild. The cost of fixing a cracked house can be determined by a professional who will work on its repair.

If the cracks are very large and deformation occurs in different directions, then screeding the house with reinforcement will not be able to completely eliminate the defects; it is designed to reduce lateral forces; in order to completely fix the house, it is necessary to strengthen and strengthen the foundation.

How much does a house screed cost?

Screeding a house with reinforcement, the price of which depends on the professionalism and quality of work of the performers. These renovation work are a good and reliable solution for repairing small cracks and they are widely used in practice.
But we should not forget that independently tightening a house requires serious knowledge in welding; if this knowledge is missing, then it is better to trust a specialist to carry out all the planned repair work.

Reinforcement is a collection of interconnected particles and elements, which, together with a material such as concrete, in reinforced concrete structures are perceived as beams that stretch the tension. Reinforcement is also used to enhance the durability of concrete in columns.

Reinforcement elements are divided into rigid (angles, channels, rolled I-beams) and flexible (periodic and smooth profiles, as well as knitted or welded frames and meshes).

Let's consider the classification of types of reinforcement.

Depending on the purpose, the fittings are:
- working (the cross section is determined by calculation, the forces are perceived in the particles of the main load);
- structural (distribution fittings that absorb shrinkage/expansion, exposure temperature);
- installation (installed to combine the structural and working parts); - anchor (embedded parts).

Depending on the orientation in the structure:
- transverse reinforcement, which actively prevents the formation of cracks from stresses around the supports and connects concrete from the compressed zone to the tensile zone with reinforcement;
- longitudinal reinforcement that fully absorbs tensile stresses and prevents the formation of cracks in stretched zones of the structure.

Depending on the conditions of use, the fittings are:
- non-stressed;
- tense.

In pre-stressed reinforced concrete structures prestressed reinforcement is exclusively working.

There are five possible options for contact between reinforcement and concrete:
- contact with concrete structures by friction;
- connection on shear bonds;
- adhesion (the process of joining when concreting a steel reinforcing element);
- interaction of cement mortar and steel reinforcement at the electrochemical level;
- compression of reinforcement using concrete after its shrinkage.

Before the beginning exterior finishing walls of any building, work should be done to level them. For this purpose, a screed is installed on the walls. In addition, with the help of wall screed it is possible to get rid of cracks on the walls of the house. Let's look at how to technologically correctly construct a screed for the walls of a house.

Screeding the walls of a house: device and technology

There are several options for performing plaster on the walls of a house:

• performing plastering as a rule, without preliminary installation of beacons, this method appropriate when there is a slight horizontal difference between the walls or if the walls are absolutely even;
• If there are large irregularities and deformations on the surface of the walls, beacons are used to level them.

If we consider the process of manufacturing wall screeds in relation to SNIP, then three options for plaster should be distinguished, depending on the final result and the quality of the work performed:

1. Simple plaster and its application to the walls are ultimately characterized by deviations of no more than three millimeters. Smooth unevenness is allowed, no more than six by eight square meters. In this case, the depth of the unevenness should not exceed five millimeters.

2. An improved version of the wall screed requires more stringent execution rules. For one square meter vertical walls, a difference of 2 mm is allowed. Smooth irregularities that are present on the walls should not have a depth of more than three millimeters. Horizontal deviations are no more than two millimeters.

3. A high-quality version of the wall screed is distinguished by the presence of deviations of no more than one millimeter. Small irregularities and deviations with a depth of no more than one millimeter are allowed.

Screeding the walls of a house using beacons: features of the process

If there are cracks and significant unevenness on the walls, this particular screed method is used. The cost of performing this process is about four hundred rubles per square meter. Therefore, without hiring builders, you will be able to save a lot.

To complete the work, you will first need a hammer drill and a level with a water bubble inside. In this case, the length of the level should be 200 cm. Next comes the process of selecting a mixture for plastering the walls. Most often, for these works, compositions based on the use of cement or gypsum are used. Usage gypsum mixture relevant in such cases:

• no cracks, even if the plaster layer exceeds five centimeters;
• complete absence of shrinkage;
• a high level of plasticity ensures ease of working with this material;
• lightness of weight also ensures work with this material, in addition, the gypsum solution has good adhesion to any of the bases on which it is applied;
• high level of vapor permeability, thermal insulation, sound insulation;
• no need to use reinforcing mesh to strengthen the walls.

Plaster beacons have the form of narrow metal profiles, on the surface of which there are holes that limit application plaster mixture. When the beacons are carried out using the rule, excess plaster is removed from the surface. Most often, the rules are about three meters long, and the depth varies from 0.6 to 1 cm. The rule has the shape of a long aluminum strip, the sharp edge of which allows for the leveling of the plaster mortar when making a screed. The rule also checks the surface for uneven areas.

To complete the work of screeding the walls of a house, you will need:

• plaster composition;
• beacons of a certain depth, depending on the thickness of the plaster;
• a perforator and a special nozzle with which the solution is mixed;
• dowels and self-tapping screws of quite long length;
• screwdrivers and building level;
• grinders or metal scissors, with which the beacons will be cut;
• hammer, plumb line and rules made of aluminum;
• wide spatula and steel rule;
• primers on acrylic base, primers for concrete surfaces;
• wide brush;
• roulette;
• protective clothing.

After preparing all the tools and materials for work, the process of screeding the walls follows. First of all, you should prepare the walls and install beacons on them. The easiest way to perform this action is to use laser level. Please note that the installation of beacons should be given Special attention, since the final result of the work and the evenness of the walls depend on the quality of this process.

Screeding house walls photo and preparation for work

Before starting work, you should inspect the walls for irregularities, deformations, and cracks. To do this, place a level on the walls and check their levelness. A long rule will help you detect defects on the walls in the form of bumps and depressions. Irregularities that were found on the walls should be noted with a marker or pencil.

Next follows the process of marking for the installation of beacons. Consider the option of having a wall with a door on the side. In this case, the first two beacons are installed on the sides, retreating about thirty centimeters from each corner. The installation location of the beacons is indicated using a marker or pencil. The further interval between beacons is from 1 to 1.5 m.

Please note that the length of the beacons should be longer rules. An equal distance is set aside from the floor and ceiling at which the beacons will be installed. The extreme points of their fixation are indicated by self-tapping screws. For more reliable fastening of beacons, dowels should first be installed.

A horizontal cord should be pulled between each corner of the wall. The length of the lighthouse is removed from the previously installed dowels and a self-tapping screw is also installed on the dowels in the upper part of the wall. A cord is stretched across the top of the wall. as well as on the bottom.

At the intersection with the markings, beacons are installed according to the previously marked pattern. Before this, self-tapping screws and dowels are also attached to the wall. The resulting holes are located in two rows, the screws located in the corner are unscrewed, but the dowels remain.

When preparing walls for applying plaster, first of all, you should clean them of dirt, dust, degrease and dry the surface. Next comes the process of applying a primer to the walls, it will help increase adhesion to the surface. In addition, the absorption of moisture on the surface of the walls will decrease. The primer is applied in several layers, special attention is paid to walls made of aerated concrete or brick.

If the wall surface is smooth, then using Concrete Contact is sufficient. If the surface of the walls is porous and absorbs moisture well, it should be treated with soil deep penetration. Only after the walls have completely dried should you further work for the manufacture of their screeds.

Next comes the continuation of the markup. Install two screws on top and four in the corners. After installing the screws, adjust their location on the wall so that they are located at the same level. The line must be absolutely vertical. The second screws are also installed vertically. We remind you that the technologically correct execution of plaster depends on the quality of this process. A plumb bob or laser level will help you get the job done.

Next, check the beacons for evenness of their installation; a cord is stretched over all screw heads. Install a small part of the beacon under the cord, you can take it from the leftovers. The beacon should be freely located under the cord on all sections of the wall.

The cord will help you edit the location of the screws along the central part of the wall. Do the same on the bottom row. Only after each of the screws is in the same plane with each other does the process of fixing the beacons begin.

Instructions for installing beacons for plastering walls:

1. Beacons must be cut strictly according to the distance between the upper and lower screws. To fix the beacons you will need a little plaster mortar.

2. Do not prepare too much mixture, as it will harden and become unusable.

3. The solution should have a curd-like consistency. The plaster should be held tightly on the spatula.

4. The plaster should be applied along the lines of the beacons and its excess should stick out beyond the screws. Install the beacon in such a way as to ensure its uniform installation both at the top of the wall and at the bottom. It is best if the work is performed by two people.

5. A long level or rule will help determine the evenness of the installation of beacons. Next comes the process of removing the screws from the wall. Please note that when using a rule, it must be cleared of solution before further use.

Screeding the walls of a house with your own hands: technology for applying plaster mortar

After fixing the beacons, the process of applying plaster follows. To do this, follow the instructions below:

1. Fill the bucket a third with water, add a little solution and mix the mixture using a drill with a mixer attachment.

2. Please note that the thickness of the solution directly depends on the thickness of the applied layer. The minimum density of the solution should be such that it flows off the spatula and holds well on it.

3. It is best to study the instructions from the manufacturer before diluting the plaster composition.

4. If the surface of the walls is made of materials that are highly absorbent, then before applying the plaster composition, it is recommended to moisten them with water.

5. Wet the areas gradually, before applying the plaster, using a spray bottle.

6. Otherwise, moisture from the plaster will transfer to the wall and it will begin to crack.

7. Professionals who carry out work on plastering walls apply the plaster solution using a yarn over.

8. If you do not have experience in carrying out such work, then the easiest way is to apply the plaster on a trowel, and then distribute it over the wall.

9. The wall is leveled from the bottom to the top. At the same time, the plaster should be different in density and should not extend beyond the beacons.

11. If there are uneven or blistered areas on the wall, then to remove them, you should remove the plaster mortar and reinstall it. Next, you should level the area using the rule.

12. The final smoothing of the surface is also carried out using the rule. At the same time, excess mortar is thrown onto the wall. Further actions are repeated in the same order.

13. After plastering all strips, areas near the floor and ceiling should be plastered.

14. In these places the solution is applied with a slight overlap. The leveling of these areas is carried out in relation to the wound plastered surface along the beacons. In this case, the rule is held in a vertical or inclined position.

15. To check the result of the work, apply a rule to the wall under different angles and on different areas walls

16. Use a trowel to remove excess plaster mortar. If there are cracks on the surface of the walls, use a liquid plaster solution to remove them.

17. If there are metal beacons on the surface of the walls, care should be taken to remove them. Since after a certain time they will become covered with rust.

18. To remove the beacons, use a screwdriver; to seal the resulting cracks, use a plaster solution. Movements during application of the solution should be x-shaped.

19. If there are too large differences on the surface of the walls, the process of screeding is carried out in two stages.

20. The first layer is applied without leveling, before it hardens, uneven notches are made on it using a spatula. They will become the connecting element between the two layers and ensure reliable adhesion of the plaster to the wall.

Screeding the walls of a house with reinforcement is done if there are large cracks and deformations on the walls. Most often, a special metal mesh is used to strengthen the wall. They are laid between two layers.

The final stage of work on screeding walls is grouting the plaster. Work should be carried out until the plaster is completely dry. Before grouting, the wall is additionally moistened.

The liquid solution is applied to the wall of the trowel. The tool is installed in relation to the wall at an angle of forty-five degrees. Strong movements smooth the surface. When the solution no longer accumulates on the surface, move to the next area, pre-moistened with a spray bottle.

Please note that if further finishing of the walls will be done using tiles, then grouting is not necessary. Since small irregularities will accompany good adhesion of the tiles to the wall.
