Before After

In Durham-Sud, a homeowner was facing recurring problems with cracks in the foundation walls, despite using traditional waterproofing products. As shown in the “before” photo, these solutions merely repeated the cycle of failure, with cracks reappearing over time. Recognizing the absolute need for a reliable solution, we implemented our advanced FlexiSpan system. In the “after” photo, you can clearly see how our innovative three-step process created a durable and effective waterproofing system, designed to remain intact even in the event of slight movement. FlexiSpan uniquely manages rain, groundwater, and hydrostatic pressure by directing any water infiltration toward the perimeter drainage system. Unlike standard mortar applications, which offer only a temporary solution, the reliability and durability of our solution more effectively ensure the structural stability of the foundation. As a result, homeowners enjoy long-term peace of mind, enhancing the foundation’s resilience against harsh conditions while reinforcing its structural integrity.

Our Basement Waterproofing Solutions in Lefebvre

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. We offer free estimates on any of our crawl space encapsulation and repair services in Lefebvre.

Job Stories From Lefebvre, QC
From recurring cracks to a lasting solution in Durham-Sud, Quebec

For this project in Durham-Sud, our team was called in to address a foundation crack issue causing recurring water leaks in the basement. The homeowner had already attempted several temporary repairs using traditional sealants, but the cracks kept reappearing over time due to ground movement.

After a thorough inspection of the foundation, we recommended installing our FlexiSpan crack repair system, a durable solution specifically designed to withstand the natural movement of foundation walls. The work began with preparing the cracked surface, followed by the application of our exclusive three-step process to ensure a flexible and long-lasting waterproof seal.

Thanks to the FlexiSpan system, any water infiltration, hydrostatic pressure, or moisture from the ground is effectively directed toward the perimeter drainage system rather than penetrating the basement. Unlike repairs using mortar or standard sealants, this method offers long-term protection against foundation cracks and moisture issues.

The end result provides the Durham-Sud homeowner with a more stable foundation, a basement better protected against water infiltration, and lasting peace of mind. This project demonstrates the importance of using a specialized foundation repair solution to ensure the structure’s strength and durability.
