When water seeps into a stairwell and you already have a sump pump system in another basement room that is draining water, we can help you fix the problem with an interior waterproofing system.

Our solution: install an internal foundation drain that catches water from the ground under the stairs and on the walls of the staircase and discharges it through a pipe connected to the sump pump a little further.

It is an effective and discreet solution and once the drain is covered, you will not even see it anymore.

Here is a photo during the inspection that contains the annotations of the basement waterproofing specialist and a photo of the result once the system is installed. Once the concrete has dried, you do not notice any difference other than the fact that your basement will be dry!

Our client from Mercier had cracks in her foundation. He also noticed slopping in some of his first level floor, which is due to an underlying problem in his crawl space.

Our technicians led by foreman Jerry have then installed 7 SmartJack support pillars.

The SmartJack is a support beam designed by engineers that adjusts to the exact height between the solid base and the support beam at the top.

Job Stories From Mercier, QC
Pillars and support for the foundations of a crawl space in Mercier, QC

Mrs. Francine, a resident of the city of Mercier, is going to sell her house very soon, but recently discovered cracks in the foundation which is problematic for a house on the market. Our foundation repair specialist Jerry went to do an inspection to analyze the problem in depth to recommend the best repair solution that will be most effective.

Jerry, therefore, recommended the installation of 7 SmartJacks support pillars that are made of galvanized steel. SmartJack beams are anchored in solid earth and help weak foundation walls withstand the weight of the house to secure space and stabilize foundations.

We will do the repairs in late May. Stay tuned to see the photos of the project once it is completed!

Water seepage in a basement in Mercier, Qc

Water was seeping into our client’s stairwell in Mercier even though they already had a sump pump system in another basement room that was draining water.

Systèmes Sous-sol Québec helped them fix the problem with an interior waterproofing system.

Our solution was to install an interior foundation drain that catches water from the ground under the stairs and on the walls of the staircase and discharges it through a pipe connected to the sump pump a little further.

Since the bottom of the stairs was where the most water seeped, we installed the WaterGuard Interior Foundation Drain that traps water from the floor and the edges of the stairs.

This solution is very effective and discreet, and once the drain is covered, you will not even see it anymore.

Our work is done, and this place is now completely waterproofed!
