Frequent masonry problems

Load-bearing wall

A load-bearing wall is intended to support and stabilize the overall structure of a construction. More specifically, to support the frame and structure of the floors.

CAUSE

The main causes of a problem related to load-bearing walls are problems related to foundations.

CONSEQUENCES

The appearance of cracks on a load-bearing wall deserves close attention. The majority of them will be of no consequence, however, they remain to be watched. Some are deep and wide, showing a cracked wall. These large cracks and fine cracks indicate that the solidity of the wall is affected and that there is possibly the presence of a belly-beef. Structural problems can then emerge.

SOLUTION

  1. Support the wall and build a temporary frame;
  2. Dismantle and partially or completely rebuild the wall, depending on the extent of the problem.
