Characteristics of object:

Screw pile technology was chosen due to collapsing and settlement of old house foundation.

On this kind of foundation,tilting occurred at the ground level, and at freezing and thawing lifting of foundation occurred, due to what wider and larger cracks appeared in walls that indicated that house is in such stage that endangers living possibility. In order to solve such problem, screw piles were assembled at the external perimeter of house, which were connected to collapsing foundation with specially manufactured bracket, and additional double T240mm beam at the corner, that later was covered with concrete coating.
