Before planning an addition to the house, you need to plan the work so that both constructions have the same penetration of the foundation, and it is best to build so that the foundation was common.Otherwise with time necessarily occurs cracking in masonry.
If the brick wall is still proved susceptible to deformation, to begin to objectively assess the extent of damage.Give up the desire to seal the crack with cement mortar, this measure will be ineffective and temporary.
If the crack on the wall has a local character and small in size, replace the damaged area, without having to dismantle the entire wall.It does not need to disassemble the bricks, if the crack
s formed only under the supports overlapping structures.Replace part of the masonry under the legs, under the Preliminary overlap temporary attachment.
If there are minor destructive cracks that appeared after the shrinkage of the building from the outside and the inside of the wall mounted metal plates, hold them together with bolts.
If the deformation of the support structure of the building is damaged, strengthen its brickwork, laying every fourth seam steel bars with a diameter of 3 mm.Strengthen the support can also be steel angles, steel strips connecting them, then place the repair will be coated with concrete.In some cases, it is advisable to replace the support, which will require pre strengthen all structures that transmit the load on the support stand.
If the cracks are united among themselves and with vertical joints, leading to flaking masonry, disassemble the clutch and route the desired foundation.After laying the foundation to a depth sufficient to re-lay the wall.
Tip 2: How to fix a crack in the house
crack in the house not only seriously spoil its appearance, but also reduces the strength, and sometimes leads to crash of the house.Through such damage penetrates the water and reduces the level of thermal insulation.At the first appearance of cracks need to be corrected immediately.
Solution cracks selected according to their causes, and the degree of destruction of the building.The cracks are the result of precipitation of individual sections of the walls.Due to the compressibility of various soil or erected additional superstructures designs are moved and displaced at the wall load.Proceed to plugging these cracks only after eliminating the causes precipitation of the walls and structures to strengthen themselves.First Seal them with cement mortar, and then install the tendons strands that will prevent stretching.They are performed from various sections of the reinforcement wire.Strengthen those portions of the walls are damaged.The ends of the cord to tighten the bolts, which perform the pre-threaded on the ends of the wire.
Cracks can also occur in a building that had not been heated for a long time.When freezing, thawing and then freezing the ground is uneven the walls, causing their displacement.Such cracks often occur between the inner and outer walls, and this leads to instability of the structure.Therefore, to reduce the swelling of the soil, it must be warm.To do this, the project is still in the process of overfill is required to under the building basement.And if you still have any crack, deep Seal them with cement mortar and install the mounting internal and external walls.
Cracks appear from direct sunlight and extreme temperatures.They usually occur on the staircases and on the upper floors.To avoid severe damage to the building, repair the cracks using over heels, steel clamps, bands or by injection grout.If the cracks are minor and are not dangerous, but only disturb the aesthetic appearance of the building, then eliminate them by applying decorative finishes of walls.
Sometimes cracks can occur during drying concrete.They are formed on the facade or plaster building.To eliminate them stretch nylon mesh or do unravel and grout.
Whatever plan is not cracks on the wall of your house, they are buried immediately, or over time, they will lead to the destruction of the building.
