Stabilization and Drainage of a Basement Affected by Moisture in La Presentation, Quebec

Challenge

At La Presentation, a homeowner was dealing with persistent water infiltration, significant moisture, mold stains, efflorescence on the foundation walls, and cracks resulting from increased hydrostatic pressure. These signs are typical of Quebec basements exposed to poor drainage, high water tables, and intense seasonal variations. After a complete technical inspection, including an assessment of the water level, structure, ambient humidity, and performance of existing drains, our team implemented an integrated solution to stabilize the basement permanently and restore a healthy and functional environment.

Solution

Detailed solution

• Thorough installation of the WaterGuard® system: creation of continuous interior drainage along the slab-to-wall junction, precise excavation of the slab, installation of a collection channel designed to intercept water from cracks, foundation walls, and the slab. The system then directs the water to a centralized management point, while reducing the hydrostatic pressure exerted on the structure.
• Integration of the IceGuard® device: installation of an external diversion mechanism designed to operate even when outdoor pipes freeze. This system allows water to be automatically drained in the event of a blockage, preventing any risk of backflow into the basement during periods of severe frost.
• Installation of SuperSump® with sealed sump: insertion of a high-efficiency sump pump into a sealed basin equipped with a moisture-proof cover. This pump ensures rapid drainage of water to the outside, supported by a durable motor, a reliable switch, and components designed to respond to seasonal fluctuations and episodes of heavy infiltration.

Thanks to this comprehensive intervention, the basement now benefits from lasting protection against water and moisture, reliable drainage in all seasons, and a better-preserved structure. This renovation has given the owner a dry, stable, and safe space that complies with best practices for water management in homes.
