The repair experts

Groupe A1 is a specialist in the repair of paving stones, steps and walls. The most common examples are residential car parks or the collapse of a foundation. Our mission is not only to fix it, but to prevent problems.


For several years, installation techniques have evolved a lot. Before, paving joints were made of sand or rock dust. Today, the joints are made of polymer sand, which is much more resistant to bad weather in Quebec. This type of sand prevents the emergence of weeds and ant nests in joints.
