Foundation Reinforcement and Interior Crack Repair Solution in Laval, QC

Challenge

Our client, Mr. Hani, residing in Laval, QC, was experiencing leaks and flooding in his basement due to a foundation crack, which was causing the wall to bow inward.

Resolution

At Sous-Sol Confort Inc., we use a high-pressure polyurethane injection technique to effectively seal the crack deep within the foundation. We proceed by injecting polyurethane into holes drilled along the crack at intervals of 4 to 12 inches (10 to 30 cm) and at a 45-degree angle, allowing us to treat the crack at its center, within the concrete foundation wall.

Next, we install ports and pump the polyurethane resin from the crack to the exterior soil, ensuring optimal waterproofing.

In addition to this solution, we use a carbon fiber system, a cutting-edge technology for stabilizing and reinforcing basement walls. This technique relies on fiber-reinforced polymers and high-strength epoxy resin, offering ten times the strength of steel while being completely rust-proof. These reinforcements are installed entirely inside the basement, without requiring any exterior work.

Conclusion
