All constructions are liable to be affected by defects. The presence of poor workmanship in the construction weakens the affected building and promotes the appearance of disorders, such as cracks and humidity. In order to preserve the integrity of the construction and limit risk taking, it is best to ask us for advice.

The structural exterior walls of single-family homes are often made of concrete blocks joined by mortar joints. Their outer face is sometimes covered with a cement-based hydraulic coating, made on site, or a single-layer coating, ready to use (industrially manufactured).

The appearance of structural cracks in the masonry linked to the functioning of the wall, under the effect of certain stresses, is one of the forms of the disorders that can affect this type of wall.

These cracks can be through and cause water infiltration.
