How to close the crack in the wall

There are several reasons for the appearance of cracks in the wall of the building. Only determining the reasons for their appearance, depth and sizes, the method of eliminating the problem is selected. The appearance of cracks in the walls indicates negative processes occurring at home, immediate response is required.

Timely measures taken to eliminate cracks and strengthen the foundation will prevent further destruction and stop deformation processes. Sailing the foundation leads to a breakdown of bearing walls and the destruction of the whole house. For cracks in brick walls, there are several methods of repair, which differ from how to eliminate them in concrete walls.

Causes of the appearance of cracks in the walls of the house

Most often the reason for the appearance of cracks in the walls of the house is the deformation of the foundation or the overall shrinkage of the house after the construction.

1. As a rule, two years after the construction of the house to complete the process of natural shrinkage. Depending on the composition of the soil or internal soil changes, this process can be delayed or after some time will resume.
2. Sailing the foundation can be caused by the soil flushing with soil. In such cases, before starting work on the repair of cracks, drainage is shutdown in the walls around the perimeter of the foundation and waterproofing is made.
3. Natural natural factors, such as deep repeated frosting and defrosting the fitting of the ground or the foundation itself, can lead to deformation processes. To combat the freezing, the insulation of the foundation and the breakfast is used.
4. In the case of design flaws and improper distribution of loads on the foundation, it also sends and deformation. In this case, without global alterations and bringing in line with the norms of the constructural details could not do.

Cracks may appear in the case of using low-quality materials when booking the foundation or violation of technology. With a non-uniform graze of concrete after filling the foundation, it loses its strength.

Elimination of cracks on interior walls

Small cracks up to 5 mm wide, not prone to magnification are very simple. Without global alterations and great repair.

1. The spatula and the korch is the crack. All weakly holds of plaster parts, fragments of brick or concrete are removed. Then the crack is moistened with water and is thrown by cement mortar. After setting and grappling the cement mortar, the crack is sweeping with a plastering solution and boils into the finish putty.
2. It is allowed to seal small slots or cracks by mounting foam. After hardening the foam, the sharp knife removes extra influx and are deepened by 2 cm. The region is then embedded with cement mortar or placed with putty.

Repair of medium cracks in the walls of the house

Average cracks relate to the category of critical and require juicy measures. Such gaps and cracks will necessarily increase what threatens the destruction of the house.

1. Works begin after the moment of attenuation of the crack expansion. In order to trace the progress and determine the moment of attenuation, the beacons are installed on the crack, and then follow their integrity. Make beacons made of plaster or firmly glued paper tape.
2. Cracks are cleaned of garbage stuffed into them, all badly holding pieces of laying or fragments of the concrete wall are removed. Around the crack removes stucco to brickwork or concrete. A cement mortar with small rubble is thrown into the gap. Small pebbles of the appropriate size are inserted into the gap and the hammer is tamped.
3. Along the crack, holes are dried at a distance of 15 cm from the edge. Anchors or crutches are inserted into the openings to which the metal strip is attached - the lining. The ends of the strip are strifted towards the wall and squeeze at the time of fasteners.
4. Such horizontal linings are installed along the entire length of the crack in 20 - 25 cm. The reinforcement metal mesh is installed on top of the lining and the damaged area is placed.

Liquidation of large cracks in the facade wall and foundation at home

Large cracks, as a rule, hide the base of the house. Therefore, their elimination in the walls is done simultaneously with the repair of the foundation.

1. At the passage of a large crack, a trench is rotated on the depth of the foundation and in a width of about 1 meter from the edges of the cracked. All weakly holding or deformed masonry bricks are removed. The crack is expanding and cleaned from garbage.
2. Work on the sealing of a large crack in the wall begins with the foundation. In the fracture according to the foundation, a cement-crusched solution is stuffed. Armature crutches are clogged along the crack, and the lining of the metal strip or fittings is welded to them.
3. In case of sending the foundation, the support beams are becoming under it. For beams use concrete pillars, a metal channel, a 2-way or pipe. The beams are perpendicular to the length of the foundation. It is important that the beams performed from under the base half the meter. Then they are associated with welding and reinforcement rods. The educated platform will prevent further sending the foundation.
4. To eliminate the consequences of the harmful effects of moisture or frost - waterproofing and the insulation of the foundation is made. The surface of the foundation is purified from dirt and covered by waterproofing mastic. For insulation, any material suitable for operation in the ground is used. It is convenient to work with Polyopolmineol, Mineral Watt, etc. Along the way, a drainage system for removal of ground and sedimentary water is done. Then there is a breakfast of at least 0.5 meters wide.
5. Having finished with the foundation, cloth close up in the wall. Inaccessible narrow spaces are filled with cement injections. For this, the inch holes are placed along the entire length of the crack in increments of 20 - 25 cm and are filled with cement mortar. For filling wells, a special injection syringe is used. It is a metal pipe with a piston and rubber seal. It takes a cement solution and is injected into inaccessible places.

The selected brick is exactly stacked at the same place. If necessary, you can add a new brick or close the space by stones. The masonry is made by a brick lock with the inclusion of metal ligaments made of fittings or stripes.
