Sometimes, for no apparent reason, they beginCracks appear on the walls of the house. In itself, this phenomenon is not terrible, but it means that the foundation sags, and this poses a danger to the whole structure as a whole.
In this case, the foundation of the house should be immediately strengthened, before it is too late, to stop the deformation at the very beginning.
First of all, determine for what reasonSubsidence occurs. There may be several reasons: a soil with different density along the perimeter of the basement, the building of a building on two separate foundations, the erosion of the foundation under the foundation. In the dry season, make a selection of the soil at short intervals throughout the foundation and compare the soil density, composition and moisture of the samples.
If the soil on the subsidence of the foundationLoose, and the samples have increased humidity, this indicates the erosion of the foundation by groundwater. It is also possible that leaching occurs due to an improperly designed sewage system or leaks in the water supply system. Check these systems for possible malfunctions. In such a case, drain the foundation by using a drainage pipe in the foundation of the foundation or drainage channel, reinforce it with concrete pouring.
If the soil throughout the site is dry enough,But has a different density, this is the reason for the subsidence of the foundation due to the uneven distribution of the natural subsidence of the soil. In this case, it is necessary to strengthen the foundation of the house, as much as possible increasing its footprint. To do this, break the base of the foundation, move the armature under it and pour concrete along with the protruding edges of the reinforcement. Thus, you can redistribute the load and stop the drawdown. In order to avoid violation of the integrity of the foundation, in another area the spillage with concrete must be carried out along the entire perimeter of the house.
Most unpleasant when the building is onTwo separately executed foundations. In this case, in addition to the above actions, most likely, it will be necessary to install a belt from the reinforcement, or to make a common screed, when pouring concrete into the basement foundation.
In general, the strengthening of the foundation is better entrusted to professional builders, since in this issue there are many nuances and subtleties.
