Excavation for French drain installation

The installation or repair of a French drain cannot be done without excavation. This is a crucial step that requires dexterity and thoroughness - and thus it is essential to hire professionals.

A mandatory step

Excavation is the first step for all foundation work. Whether it is for a French drain installation project, waterproofing or an external crack repair, a soil excavation must be performed to reach the base of the footing, i.e. a hole is dug to reach the foundations of the house.

Make a locate request

In order to avoid a possible breakdown of underground infrastructure (gas pipes, electrical wires, sewer and water systems, etc.), the Régie du bâtiment du Québec (RBQ) considers it essential to inquire about the presence of buried facilities near the site.

Our team does it for you
Each time an excavation is carried out, a locate request is submitted by our team to Info-Excavation, an organization whose goal is to prevent damage in Quebec. Such a request not only avoids any possible breakage, but also ensures a safe environment for workers.

Excavation, a practice dedicated to experts

This is a delicate step for many reasons. Restricted access, landscaping and the various pipes or electrical wires buried around the residence are just a few examples of what to consider when excavating.

Trust our experts, they will take all the necessary precautions to carry out the excavation work impeccably
