Here is another wet crawl space but this time it’s in Coteau-Du-Lac, Qc.

Our client was complaining about the damp area and the mold growth that was spreading into his house.

After her call and the place inspection, we recommended him to install a CleanSpace membrane to block water vapor; a TerroBlock insulation system that is specially made for crawl spaces, and finally a SmartSump pump to pump all the water out of the area and reduce the moisture in the place.

This pedestal pump in Coteau-Du-Lac was getting clogged most of the times, which was preventing the pump from extracting water from the sump pit or sump liner.

Our customer then opted for our SuperSump pump system that has a  CleanPump stand; this patented stand elevates the sump pump intake port to help prevent clogging, which is a common cause of pump burnout.

We have encapsulated and waterproofed this crawl space in Clarenceville that was undergoing many problems such as heat loss and wasted energy, water infiltration, mold and more.

By installing our CleanSpace Liner to solve the problems of water vapor, our CleanSpace matting to collect water from the crawl space floor and direct it to the SmartDrain, the place is now totally sealed.

Our Basement Waterproofing Solutions in Coteau-du-lac

Basements are a common spot for water intrusion in homes due to the soil around them. When soil gets wet, dries out, or is displaced, it can cause shifting around the basement and lead to cracks or other vulnerabilities in the exterior wall. Though this is a common problem, the right solution for your home can be a unique combination of techniques and products. Thankfully we carry all of the most up-to-date basement waterproofing products available, including sump pumps, perimeter drains, wall repair products, and more.

Don't let water intrusion stop you from using your basement the way you want to. Whether it's a simple storage area or you're looking to finish the space, keeping it dry will do wonders for the long-term health of your home.

Foundation Repair & Structural Improvements by Systèmes Sous-sol Québec

Foundation problems can affect your entire home in significant ways. If the foundation shifts out of place, it can no longer properly support your home and may result in slanted floors, cracked walls, cracked ceilings, windows and doors sticking in place, and more. Similarly, when your foundation is cracked it can allow for serious water intrusion or pest infestations. Both pests and water use foundation cracks as their way into your home where they wreak havoc, especially when mold begins to grow. What starts as mold or mildew around the foundation can negatively affect whole-home air quality from top to bottom and result in wood-rot, compromising the structural integrity of your home.

Foundation products & services we offer:

  • Push pier systems
  • Helical foundation piers
  • Crawl space supports
  • Basement wall anchors

With our full suite of foundation repair products, we can address almost any foundation problem you may be having. Unsure about the health of your home's foundation? Start with a free inspection and cost estimate from us.

Crawl Space Encapsulation, Sealing, & Other Repair Services

Systèmes Sous-sol Québec installs the unbeatable CleanSpace® crawl space encapsulation system that will take your crawl space from dirty and useless to clean and usable storage space. In addition to sealing off your crawl space and making it waterproof, we also offer crawl space jacks for structural support and prevention of sagging crawl space ceilings— this will also help prevent sagging of floors above the crawl space. To finish off your new crawl space, we also install access wells and thermal insulation to protect your property.

The CleanSpace® system completely transforms your dirt floor crawl space into a sealed environment, dramatically reducing the humidity levels. Lower humidity levels can reduce or eliminate mold growth, rot, and pests from your crawl space. This ensures long-term home health and air quality, starting with your crawl space.

Job Stories From Coteau-Du-Lac, QC
Humidity in a crawl space, in Coteau-du-Lac

Mr. Serge had moved into this house 8 years ago and from the first year, he realized the situation of his crawl space. In fact, he didn't necessarily know the state of this space, since he didn't really want to go check it out, but he realized that the damp smell was probably coming from there. He told himself that if he could smell the humidity, the situation must be serious. He therefore contacted us to be clear.


 Once our Certified Specialist John completed the full assessment, he found that there was water infiltration into the crawl space. This caused the humidity to increase in the house and the smell affected the air quality of Mr. Serge's family. The customer decided to go with an encapsulation solution with our CleanSpace product as well as our SaniDry dehumidifier. Mr. Serge can not only benefit from a dry crawl space, but can also optimize space thanks to the storage available .

Mr. Serge had purchased this property knowing that it had a crawl space. He knew the state of it well and he had been thinking, for the last 8 years, that he should waterproof the space.

He actually feel a water infiltration, as well as a bad odor. This had started to affect the air quality on the floors. He knew well that the situation was not going to resolve itself and that he could even have a major flood in his crawl space. And since he was planning to live in this house for several years, he wanted to know that the space was dry, clean and safe for his family.


Like Mr. Serge's, crawl spaces are generally left in the construction state, which means that they are generally still uncovered, directly on the ground. The soil has a very high level of humidity so it is essential to add a membrane to separate this water from the crawl space. Our CleanSpace coating product is the best solution for encapsulating the crawl space. This will protect the space against water and humidity, but also against insects and curves. It also offers a clean white space usable for additional storage. Our team also installed our dehumidifier specially designed for crawl spaces, the Sanidry.

The client and his family now enjoy a dry home and breathe healthy air for their health.

Water infiltration problems in Coteau-Du-Lac

Our client who lives in Coteau Du Lac was having a problem in his crawl space due to water infiltration.

Mr. Serge was ventilating his crawl space during hot days. But the problem was coming from the water vapor and humidity.

So he called us in order to encapsulate his crawl space, since the humidity was attracting mold, and the air quality was not healthy.

Furthermore we installed a vapor barrier specially designed for the crawl space: the CleanSpace membrane. In addition, to dry and purify the air, we installed our SaniDry XP air dehumidification system. The water vapor is reduced to the recommended rate to make this place a healthy and usable place, adding value to your home.

After the installation, our client felt very relieved that he wouldn’t have to deal with those issues and his health wasn’t in danger anymore due to the abolition of mold in the area.

Systèmes Sous-sol Québec has designed sump pump systems to overcome many of common sump pump problems. All of the systems include cast-iron Zoeller pumps that are designed to reliably handle a variety of pumping needs.

So when Mrs. Bibeau called us, she knew that we are the right place to help her solve her water infiltration problem and her sump pump failure.

Her basement in Coteau-Du-Lac was always dry, which was attracting all kinds of bacteria, mold and moisture into the place.

When she called us and explained her problems we scheduled a day to inspect her place and for free, and once we examined her place we suggested a waterproofing system.

We then installed our Supersump pump system for an effective and more economical solution, and an interior drainage system our WaterGuard drain.

Our Waterguard system is an award-winning, patented below-floor drain that rests in a bed of drainage stone on top of the foundation footing, and can be installed quickly.

Mrs. Francine from Coteau-Du-Lac called us when she got concerns regarding her damp crawl space.

Her problems had started earlier this year, she was getting sick most of the time and she had no clue that her crawl space might be affecting her health.

Her doctor asked her whether she had mold in her house, since it will bring down her immunity, and infect her body. After several research on the internet, she got an idea about the areas where mold grow and this is when she knew that she needed to check her crawl space.

Our client has finally found our Systèmes Sous-sol Québec’ on google, contacted us and following her call we sent a team of Professionals to perform a complete encapsulation of the crawlspace.

Furthemore we installed a a CleanSpace membrane to block water vapor with the drainage matting,  a TerroBlock insulation system that is especially made for crawl spaces, a SmartSump pump to pump all the water out of the area and finally our SaniDry dehumidifier that reduces the moisture in the place.

After the installation, Mrs. Francine’s health has improved so much, and she felt really comfortable knowing that mold is gone, and the place is so clean and uncontaminated.
