Our customer’s foundation in Lachute was curving, which is a serious problem and sign of failure in the basement foundation walls.

We have solved this problem, by installing PowerBrace galvanized steel beams and several smartJacks.

The beams form a system designed specifically to support the walls of failed foundations and to straighten the walls to their original position over time. Zinc coated, the PowerBrace system resists erosion, reduces abrasion and makes beams non-toxic

As for the SmartJack  Support Pillars , those are steel support systems used to stabilized and level the girders and floor joists in a crawl space.

In Addition they are super strong (support loads of more than 60,000 lbs.), and is the only solution that addresses problem soils.

Our patented system stands out from the others and we are very happy to have had the chance to install it at our customer’s place to solve his problem once and for all!

The sump should have an airtight lid on it to prevent water from evaporating out of the sump hole into the basement, to stop stuff from falling in that can clog the pump or switch, and to quiet the system.

We changed our client’s non hermetic pump in Lachute and replaced it with our TripleSafe sump pump.

This sump pump system provides the ultimate protection against basement leaks and moisture problems.

If your floor is still stone or concrete and you plan to finish it, waterproof it to solve the current problems and avoid those of the future. Before pouring your slab, we can install a CleanSpace dring mat as well as a CleanSpace vapor barrier membrane that eliminates the infiltration of water vapor. This will keep the air dry and your belongings in good condition. The CleanSpace membrane is a 7-layer polyethylene vapor barrier that contains an antibacterial additive that prevents mold from growing on the membrane.

Job Stories From Lachute, QC
Groundwater leakage in a basement in Lachute, QC

Water mostly comes from rainfall and melting snow. Even a small storm can generate a flood in the basement.

In other cases, the problem is rising groundwater, which may even be fed by an underground spring. Once the water accumulates around your foundation, it works its way inside through cracks, joints, and porous material.

After having those problems in her basement, Mrs. Julie started searching for permanent solutions, and she found Systèmes Sous-sol Québec.

At first she was hesitant about calling us, because she thought that the installation will take too much time, and the house will end up in a big mess after the execution.

But when she finally reached us, our specialist informed her that our work will only take a couple of days with the minimum cost, and our team will make sure to cover up all of her house belongings to avoid any chaos in the place.

Our team started by sealing the crack in the foundation wall, and we injected the FlexiSpan sealant which is a product that, once injected into the crack, turns into a waterproof rubbery material that adapts to wall movements so that it does not get wet nor crack again.

Then, we eliminated the water infiltration by installing a WaterGuard water drainage system that eliminates risk by capturing water that seeps through the floor and walls and finally a TripleSafe sump pump system was installed for maximum safety!

Foundation problems in Lachute, Qc

Mr. Patrick who owns a place in Lachute, contacted us after finding some serious issues in his house.

The client told us that his walls were bending and he needed our help asap!

We reserved an appointment with our specialist, and after checking up the area, we confirmed the problem, therefore, our specialist recommended the best solution with a guarantee for the whole life of the house.

In order to solve this problem, our specialist recommended the installation of the PowerBrace galvanized steel beams. The beams form a system designed specifically to support the walls of failed foundations and to straighten the walls to their original position over time.

The beams can actually improve the condition of the wall in the long run.

We also installed also several SmartJack systems.

SmartJacks are steel support systems used to stabilized and level the girders and floor joists in a crawl space.

The installation was done properly and the house is no longer in danger for getting collapsed thanks to our company’s best products available in the market!

Drying a basement in Lachute, Qc

A wet basement is more than annoying. If your basement includes finished living space, any kind of moisture can ruin carpeting, drywall, and framing.

This is what happened to our client’s basement here in Lachute.

Everything got ruined from her furniture, her belonging and floors.

Actually she tried many times to dry her basement, and airing all the condensation out by opening windows and running fans,  installing a dehumidifier in a spot near an easy drainage, in addition to using a waterproof coating on the walls, but nothing really worked out!

Mrs, Ginette then found our company on google, but was really worried that our waterproofing product's costs will be very high, but having a wet basement was costing her too much anyway!

But since all her trials were in vein, she finally decided to contact us asking for further information.

We informed our client immediately that we offer a free consultation and inspection, which made her feel such a relief and she knew that we might be able to solve her problems permanently.

The quote has been approved and we started by installing our interior drainage system ‘ the WaterGuard’ ; changing her old pump, with our company’s best Sump pump system ‘the TripleSafe’ ; installed 2 Iceguard systems which are anti-freeze systems that provide an exit when pipe terminations are blocked, and we finished it with our Lawnscape and discharge line outlet.

The Job was perfectly done according to our client’s referral, with the least cost and minimum time.

We have water seeping through the basement floor during heavy rains. I will be contacting the town to see what they will do as it is obviously back-pressure, but I would like to know the pros of installing a sump pump as well as the estimated cost - there is no existing pump well, so it would have to be dug in.
