Job Stories From Les Coteaux, QC
Elimination of water infiltration in Les Coteaux, QC

Mr. Frank wanted to keep his entire basement dry. His basement had been finished and he wanted to protect it. He therefore chose the WaterGuard solution.

Our customer wanted the peace of mind that comes with this solution's lifetime warranty. This guarantee is even transferable to the next owner, in case the house was sold .He chose the complete solution to secure the perimeter of his house and went ahead with Systèmes Sous-sol Québec, the expert in this type of work since 2007.


The WaterGuard is a drainage system that leads water to the TripleSafe pump, that will be then discharged outside the house, at a safe distance. The client can now enjoy a dry basement, year round and protect his investment.

 Systèmes Sous-sol Québec is happy to have solved Mr. Frank's problem in Les Coteaux, QC.

Water infiltration problems in les Coteaux, Qc

One of our customers who live in Les Coteaux area contacted us because the water was seeping into his basement.

Due to water infiltration, the organic materials in his place got deteriorated and humidity was reaching his house and affecting badly on its air quality.

All those problems pushed Frank to contact our company, asking for our free inspection.

We waterproofed the entire place by installing our TripleSafe sump pump to pump all the water out, 2 IceGuard accessories to prevent water freezing and a LawnScape discharge line outlet.

When choosing a sump pump system for your home, there are several features to consider. Our company’s pumping systems include an alarm, watertight cover and check valve.

After the installation, the place is completely waterproofed, and our customer is very happy with the results.
