missteps in the house design;
violation of base laying engineering;
objective changes of soil characteristics (increase in groundwater levels, moisture, soil heave, and so on.);

It is possible to begin the next base repairing only afterwards full completion of previous section. This rule is very important, because information technology will avoid farther deformation of the business firm basis.

Key renovation features and recommendations

The option of repair applied science of the existing basis depends on the overall structure condition, its further possible reconstruction, soil conditions, and the building pattern features.

Commencement of all, inspect the foundation on which your house stands and the building itself, and determine its type, if you do not know.

You lot can brainstorm the renovation work with each side but after the solution is filled in the previous section and is fully harden.
The engineering of block cracks repair is not also difficult. To do this, from every corner of the building dug pits with a minor occurrence under a concrete construction. Further, in each of wells brand a metal frame with cells measuring 8×eight inches. Ready cages are installed in pits and filled with physical mix. Such a concrete "cushion" should be left for a few days for the terminal ready.
When cracks are nowadays in the body of blocks themselves, it is better to utilize the so-called reinforced physical belt. Along building walls dug a trench width of xv-xx inches. Its depth should be half of the existing foundation. Farther, all the working processes are performed in the same way: set up a frame of reinforcement, install it in a trench and fill up with concrete. If the trench goes too far (33ft or more than), strengthening of this wall may be done in two stages (each with the half of trench length).
