Foundation Repair and Waterproofing in Deux-Montagnes, QC

Challenge

A homeowner in Deux-Montagnes contacted us due to significant water infiltration issues in the basement, combined with signs of settlement and weakening of the foundation walls. The situation was compromising not only the comfort of the building but also its long-term durability.

Resolution

After inspection, we observed:

• Presence of water related to hydrostatic pressure around the foundation
• Absence or inefficiency of the existing exterior drainage
• Foundation walls showing signs of movement and structural weakness
• Risk of worsening infiltration during spring and autumn

A comprehensive solution, both structural and waterproof, was necessary.

In order to correct the situation permanently, we proceeded with a complete approach:

• Full exterior excavation of the foundations
• Installation of a high-performance waterproof membrane
• Placement of an exterior French drain to redirect water away from the foundations
• Structural reinforcement of the walls with the Power Beam system
• Installation of a complementary interior drain to ensure redundancy in the water management system

This interior + exterior combination allows for optimal and lasting protection.

Result

Thanks to a reinforced and secured foundation, your basement is now completely dry and stabilized, benefiting from the total elimination of water infiltration and an efficient drainage system providing durable protection against Quebec's freeze-thaw cycles.
