LIFTING THE STRUCTURE
Sometimes, the operation of consolidating the foundation ground is
accompanied by a marked lifting of the structure. In fact, if the entire
building or even only the subsided part possesses sufficient structural
rigidity, with careful laser control and following a precise application
method, one can recuperate the lowering which has taken place, by means of
lifting.
The structure above must have a foundation of sufficient size and be
sufficiently rigid; if this is not the case there is a risk of causing
fractures in the walls.
The load above must furthermore be proportionate to the degree of lifting
required.
In fact, during this operation, the intrinsic structural rigidity will cause
a big proportion of the load to concentrate at the lifting point. Lifting is
obtained by simply prolonging the injections of material into the ground
below. Given that this ground will have been previously consolidated, it
will resist further compression and the expansion of the resin will occur in
an exclusively upward direction, in lifting the building.
