How to seal the crack in the wall

Sometimes several reasons for the appearance of cracks in the wall of the building.Just identifying their causes, depth and size selected method of eliminating the problem.The appearance of cracks in the walls testifies occurring at the base of the house of negative processes that require an immediate response.

Timelymeasures taken to eliminate cracks and strengthening the foundation will prevent further destruction and to stop the deformation processes.Subsidence of the foundation has skewed bearing walls and destroy the entire house.For cracks in brick walls there are a few methods of repair that are different from the ways of their elimination in concrete walls.

Causes of cracks in the walls of the house

most common cause of cracks in the walls of the house is the foundation deformation or shrinkage of the overall home after construction.

1. As a rule, only two years after the construction of homes for the completion of the natural shrinkage.Depending on the composition of the soil or subsoil of internal changes, this process can take some time, or resume.
2. foundation subsidence can be caused by leaching of the soil groundwater.In such cases, before starting work on the repair of cracks in the walls on the perimeter of the foundation settling drainage and waterproofing done.
3. natural factors, such as deep repeated freezing and thawing of soil adjacent to the foundation or the foundation itself can lead to deformation processes.To combat the freezing basement insulation used and the blind area.
4. In the case of design flaws and wrong distribution of loads on the foundation, as is its subsidence and deformation.In this case, can not do without major rework and bring it into line with the norms sopromata structural parts.

Cracks can appear in the case of low-quality materials at the foundation laying or abuse the technology.When uneven drying concrete after pouring the foundation, it loses its strength.

Elimination of cracks in the inner walls of the room

Small cracks up to 5 mm in width, not inclined to increase eliminated very simply.Without global alterations and large repairs.

1. spatula and kirochka embroidered with crack.Deletes all the little parts that hold the plaster, brick or concrete fragments.Then the crack is moistened with water and thrown grout.After setting and drying grout, puttied crack plaster solution and smoothed finishing putty.
2. allowed to seal small gaps or cracks with foam.After foam curing, sharp knife removes excess sagging and deepened by 2 cm. Then smeared site plastered with cement mortar or mastic.

Repair secondary cracks in the walls of the house

Average cracks are classified as critical and require a juicy action.Such cracks and crevices will necessarily increase, which threatens to destroy the house.

1. work begins after the time of the decay of expansion cracks.In order to track progress and determine the time of decay, a crack beacons are installed, and then monitor their integrity.Make beacons from plaster or firmly glued paper tape.
2. Cracks nabivshegosya cleared of debris in them, removes all poorly adhering pieces of masonry or concrete wall fragments.Around the crack is removed the plaster to masonry or concrete.In the slot snaps mortar with fine gravel.Small stones of a suitable size is inserted into the slot and compacted hammer.
3. drilled holes along the crack at a distance of 15 cm from the edge.The openings are inserted anchors or crutches, to which is attached a metal strip - pad.The ends of the strips bend in the direction of the wall and squeezed in time fixings.
4. Such horizontal linings are installed along the entire length of the crack in increments of 20 - 25 cm. Above the pad is set armirovochnaya metal mesh and plastered the damaged area.

liquidation of large cracks in the front wall and the foundations of the house

Large cracks tend to hurt and basement of the house.Therefore, their removal is done in the walls at the same time with the foundation repair.

1. In place of passing a large crack in the foundation dug trench depth and width of about 1 meter from the edges of the crack.All who hold weak or deformed bricks masonry removed.Crack embroidered with and cleared of debris.
2. Work on sealing of a large crack in the wall begins with the foundation.The crack on the foundation stuffed cement and crushed stone mortar.Along the crack reinforcing crutches hammered and welded them to the lining of the metal strip or a reinforcement.
3. In the case of subsidence of the foundation under it infest support beams.For beams using concrete pillars, metal channels, I-beams or pipe.Plant beams perpendicular to the length of the foundation.It is important that the beam appeared from under the base of half a meter.They are then linked using a welding rod and rebar.Founded platform will prevent further subsidence of the foundation.
4. To eliminate the effects of the harmful effects of moisture or frost - is the foundation waterproofing and insulation.Its surface is cleaned of mud and covered with a waterproofing compound.To use any insulation suitable for use in a ground material.Conveniently work with polystyrene, mineral wool, etc.Along the way, it is the drainage system to drain groundwater and rain water.Then the blind area is not less than 0.5 meters wide.
5. finished with the foundation, is embedded in the wall slot.Unavailable narrow space is filled using cement injection.For this purpose inch drilled holes throughout the length of the crack with a step 20 - 25 cm and filled with grout.To fill the holes using a special injection syringe.It is a metal tube and a rubber piston seal.It is dialed and the grout is injected into inaccessible places.

selected brick fits exactly into place.If necessary, you can add new brick or stone close up the space.Masonry is the brick castle with the inclusion of metallic cords from scraps or reinforcement bars.
