Foundation crack repair from the exterior in Salaberry-de-Valleyfield
Is your basement cracking?
Cracks in basements are now common, both in old and new buildings. A defective basement often shows signs of water infiltration through cracks and leaks that are sometimes barely visible.
Among the most frequent causes of cracks and infiltrations in a basement are: ground leveling, poor drainage, soil subsidence around the foundation, or the water table. In many cases, damage to the basement only becomes apparent after a significant crack or water leak appears. This is why it is essential to regularly inspect and maintain your basement, especially in older buildings.



Basement crack injection and repair: a reliable solution
Crack injection is a process that involves filling a crack throughout its width and length to stop any infiltration. From the outside, we can also use a mini-excavator to clear the foundation and access the crack from the exterior. We then clean the foundation with a high-pressure jet and inject polyurethane directly into the crack. Next, we cover it with a Resisto brand elastomeric membrane, then complete with the Delta MS membrane, which ensures complete waterproofing of the foundation and a perfect repair.

Advantages of urethane
- Expands to completely fill the crack, starting from the bottom and going upward, from the inside to the outside.
- Hydrophobic: Urethane is hydrophobic and water-resistant, making it an ideal material for applications requiring increased water resistance.
- Stretching and compression. Urethane foam can expand and compress. As the foundation undergoes microscopic movements, the repair remains intact and continues to prevent water from entering.
- Fast: Polyurethane injections begin to expand a few minutes after injection.
- Transferable written warranty.
Repairing foundation cracks: from the inside or outside?
It is possible to repair foundation cracks from the inside or outside of the house, depending on the situation. Both methods are effective. Repairing a crack from the outside involves using a mini-excavator to dig and clear the foundation to reach the problem area. Then, a waterproof membrane flexible enough to withstand movement is applied. If we have access to the foundation wall from the inside, repairing the crack is easier. In all cases, we ensure that repairs are carried out in the least invasive way possible.
For any type of crack or water infiltration, contact Sous-Sol Confort, the specialist in crack repair with or without excavation. We offer a simple, optimal, and inexpensive solution for all your projects, with excellent value for money.
