Systèmes Sous-sol Québec Before & After Photos

Before diving into the depths of this Shawinigan, QC home's crawl space, notice in the before photo how exposed and chilly it appears. The homeowner reached out to us, worried about the cold affecting their floors and overall home comfort. Our solution? A wonderful trio of our best products. As you can see in the after photo, we transformed that frosty, forgotten space into a clean, insulated haven with CleanSpace vapor barrier, SilverGlo insulation, and supported the structure with robust SmartJack supports. Now, the once cold crawl space is a pillar of warmth and stability, showcasing our mission to not only solve our customer's problems but also offer them a remarkable and lasting solution.

In Notre-Dame-du-Mont-Carmel, QC, this crawl space was dealing with persistent moisture, musty odors, and poor air quality. The combination of a concrete and stone foundation, along with limited access, allowed humidity to build up, increasing the risk of mold and structural concerns. Without proper drainage or encapsulation, water accumulation and unstable support conditions were impacting both the home’s efficiency and overall health.

The crawl space is now fully transformed into a clean, dry, and healthy environment. With the installation of the CleanSpace encapsulation system, Drainage Matting, and a full perimeter drainage solution connected to the SmartSump system, water is effectively collected and discharged away from the home through the StarPipe system and LawnScape outlet. The IceGuard ensures reliable performance even during freezing conditions. The SaniDry Sedona maintains optimal humidity levels, while the SmartJack system reinforces structural stability. Finished with SilverGlo insulation, the space is now energy-efficient, protected, and built for long-term performance.

In Notre-Dame-du-Mont-Carmel, our team at Systèmes Sous-sol Québec addressed a crawlspace issue involving persistent dampness, musty odors, and clear signs of water infiltration. These conditions not only affected indoor air quality but also posed a long-term risk to the foundation’s structural integrity.

To resolve the issue permanently, a comprehensive solution was implemented. First, a drainage membrane was installed directly on the crawl space floor to capture and divert water as soon as it enters, thereby preventing any accumulation under the house. Next, the CleanSpace system was added on top to create a continuous moisture barrier and completely seal off the space.

SilverGlo panels were also integrated to improve insulation and reduce heat loss. A SuperSump system was installed to ensure constant and efficient drainage of collected water. Finally, StarPipe was added to optimize drainage around the foundation and divert water away from the structure.

Thanks to this work, the crawl space is now dry, stable, and protected against future water infiltration. Systèmes Sous-sol Québec provides comprehensive solutions that combine drainage, waterproofing, and insulation to preserve the health of your foundation.

In Shawinigan, one homeowner had been living with the constant challenges of a damp and uncomfortable basement. Over time, excess humidity had led to mold growth and unpleasant odors, while small cracks in the foundation walls began allowing water to seep in during heavy rains. The space felt cold, clammy, and unsafe,  far from the clean usable area the homeowner wanted it to be.

To bring the basement back to life, our team designed a complete waterproofing and stabilization plan. We installed the WaterGuard drainage system, which efficiently channels water away from the home to keep the area consistently dry. To improve insulation and moisture control, we applied SilverGlo wall panels, helping maintain a healthier environment and better energy efficiency. Finally, the PowerBrace system was added to reinforce the foundation walls, ensuring long-term structural stability.

With these upgrades, the basement was completely transformed into a clean, dry, and solid space and the homeowner can now use it with confidence for years to come.

We once received the following customer request: "I want to have an inspection of my basement, because I have a problem of water infiltration and an external drain is not a possibility for us". No problem, interior drains are our specialty! So we sent our basement waterproofing expert Andrew to do a complete assessment of this damaged basement and to recommend the most effective solution for dealing with this problem from the inside.

Then we sent a crew to start the installations. They started by sealing a crack with FlexiSpan. Next, they installed a 143-foot perimeter of WaterGuard interior drain and then added a CleanSpace vapor barrier membrane to the walls. Finally, to dehumidify and purify the air, we installed the SaniDry XP dehumidifier!
