Strengthening the foundations – the most laborious process in the repair of any buildings. Selecting the way to strengthen the foundations in the first place depends on the reasons causing it. The destruction of the basement around the perimeter. With this form of destruction along the tape or on the perimeter of pier foundation digging a trench. Surface of the foundation and walls thoroughly cleaned of dirt and old plaster, and then in the design of foundations clog metal net, which, referring to a dis-tance attaches to the anchors, released from foundations and plinth of the wall. Install formwork and concreted. After curing the concrete trench to sleep with a careful layer by layer plugging.

Replacing destroyed part of the foundation. In this case, suit new and additional areas on the sides of foundation, formed in the form of masonry, stone, getting the clutch to the desired width and providing a link between old and new masonry. Foundation base is not deepened. Strengthening areas of foundations. foundations made of rubble, rubble concrete, reinforced concrete, soil-concrete and other materials satisfied with reinforced concrete broadened the clip, which closely relate to the existing masonry through anchored so as to re-made parts "worked" together with the old part of the foundation and transmit the load on the ground. Increasing the bearing capacity of the base stations. If necessary, along the weak, requiring the discharge of foundations on both sides spread a new, for which load from the overlying the building is transmitted through concrete or metal beams passing through the mounting part. Newly laid the foundations of cross-cutting anchor anchors to existing foundations for a joint "work" the old and new foundations.
