How to strengthen the foundation

At first It is necessary to find out the reason for the subsidence of the lower part of the structure. The reasons can be several: different density of soil under the building along the entire perimeter of the foundation, erosion of the basement foundation, as well as construction of the building using two different types of foundations. In the summer, you can do so-called soil sampling. Just take a few samples of the earth from different points at the base of the building itself. Then compare the taken soil on the composition and humidity.

If in a certain area the land is not dense and is slightly damp, this indicates that the foundation is susceptible toblurring by groundwater. Also, leaching is very often due to a breakdown in the sewage system or an improper operation of the water supply system. In this case, you should check the above communications for faults. If these are identified, it is necessary to make the drainage of the foundation using pipes or a special channel reinforced with concrete pouring.

If, on the whole section, on which the house stands, The soil is sufficiently dry, but it has a different density, this is also the cause of subsidencefoundation, as there is an uneven subsidence of the earth. Usually, in order to strengthen the foundation, in this case it is necessary to increase its supporting area. It will be necessary to unearth the base of the structure and bring the reinforcement under it, which should then be poured with concrete. It is also necessary to pour over its protruding edges to achieve maximum reliability and increase the area for the support.

As a rule, this way the load is completely redistributed, and the drawdown of the foundation stops. Such a procedure must be performed not only in the place of crack formation, but also along the entire perimeter of the building in order to prevent sagging from the side where the building currently stands correctly.

To strengthen the foundation, which is a combination of two separately executed foundations, in addition to the above actions Install an additional reinforcement belt along the entire perimeter of the structure and thus make a common screed.

It must also be said that The resulting cracks in the walls must be cemented with cement mortar. In addition, such injections of mortar can be made and under the filing of the foundation itself, if it has cracks and voids.

There is another way to make the foundation more durable. It consists in using the so-called vibrating stamping piles. However, this method is considered the most expensive,because it requires special equipment. Usually such piles are used in case of construction of one more floor or at creation of any additional loadings on a construction.

Finally, it should be noted that The procedure for strengthening the foundation is best entrusted to professional builders, since this issue has a large numbersubtleties and nuances. Also, it will not be superfluous to call a construction engineer to assess the drawdown and consultation, since the specialist will be able to pinpoint the cause of the problem and choose the best way to solve it.
