A crack in the foundation can be caused by several factors: 

​

• Expansion and shrinkage of concrete caused by a  temperature change.

• A movement of the foundation caused by poor bearing capacity of the soil

• Poor quality concrete.

​

Cracks in a concrete foundation are generally not a problem. They become so when there is water infiltration or when the crack gets wider and wider over time,  which means there is ground movement.

​

For their repair, we generally prioritize high-pressure polyurethane injection or an exterior excavation with the installation of a membrane.

​

On-site expertise is necessary to determine the type of crack as well as the repair to be prioritized.
