Foundation problems almost never start with a flooded basement. They develop gradually, giving you time to implement preventive solutions.
Often, it begins with a small foundation crack, a damp area in the basement or the presence of water after heavy rain.
These signs may seem minor, but they should not be ignored. Small cracks can sometimes turn into major issues.
Our team’s role is to analyze these signs and provide you with a solution to restore the integrity and waterproofing of your foundation.
Homes and commercial buildings are constantly exposed to soil movement caused by freeze and thaw cycles, as well as water pressure. Without effective drainage and waterproofing, this pressure weakens walls, deteriorates concrete and creates or enlarges cracks.
Acting quickly and properly helps prevent more serious damage.
If these situations are not addressed, you may start to see mold forming, along with material deterioration and potential structural instability.
Moisture affects insulation, drywall (Gyproc), flooring and framing. What may seem minor at first can quickly become a more complex and costly issue.

With our team, every project begins with a detailed and methodical evaluation.
Rather than simply sealing visible damage, we determine whether the issue is caused by drainage problems, excessive water pressure, soil movement or material aging.
This analysis allows us to recommend the most appropriate solution, whether it involves foundation crack repair, French drain installation or concrete slab replacement.
Our team uses high-quality materials and proven techniques to ensure long-lasting waterproofing results.
We explain every step of the work and make sure to respect your land and property throughout the process.
Communication with our clients is important to us. We take the time to clearly explain the situation, outline each step of the work and respect your property at all times.
Technical expertise matters, but trust is at the heart of our mission.
Foundation crack repair is one of our most requested services.
Foundation cracks can be caused by soil movement, excessive water pressure, temperature variations or material aging. When water penetrates, it compromises the structural integrity of the building.
Depending on accessibility and the severity of the crack, we offer either interior or exterior repair.
For exterior repairs, we excavate down to the footing of the foundation. The crack is opened and cleaned, then an A-B epoxy mixture is applied directly to the surface.
A Blueskin membrane and a Delta MS drainage panel are then installed to ensure proper waterproofing. This system provides strong protection against water infiltration.
When excavation is not possible, we perform interior repairs by sealing the cracks using drilling techniques and high-performance materials. The goal is to stop water infiltration and reinforce the affected area.

If your French drain is no longer functioning properly, it needs to be replaced.
A properly working French drain redirects water away from the foundation to prevent moisture issues.
Over time, sediment can build up or the system can lose efficiency.
A defective foundation drain increases pressure on the concrete and allows moisture to penetrate the walls.
By replacing the drain and waterproofing the foundation with a Blueskin membrane and a Delta MS panel, this pressure is reduced.
This ensures long-term protection of the structure and reliable performance over time.
Our team also specializes in concrete slab replacement, particularly for garage floors.
A cracked concrete slab can be a real hazard. In addition to safety risks, it can create drainage issues and weaken the structure.
We demolish the existing slab, rebuild a solid base and install a new slab using durable materials.
If necessary, we also replace the underlying soil to ensure maximum stability.
With thousands of completed projects, our team is recognized in the region for consistent quality and customer service.
Our mission is to provide long-lasting protection and waterproofing, with professionalism, transparency and respect for your budget.
