Foundation Waterproofing & French Drains That Protect Your Home from the Inside Out
Montréal Hardscape engineers foundation waterproofing and French drain systems that stop water at the source — keeping basements dry, foundations stable, and meltwater directed away from your home through every freeze-thaw cycle.
Water is the single greatest threat to a Montréal foundation. Between spring thaw, heavy rains, and clay-heavy soils that hold moisture against the concrete, hydrostatic pressure builds until water finds its way through the walls and slab. Our waterproofing systems relieve that pressure before it reaches the structure.
We install exterior French drains — perforated pipe set in clean stone and wrapped in filter fabric — around the footing to capture and redirect groundwater away from the foundation. We pair it with membrane waterproofing on the foundation walls, drainage board, and proper grading so the entire system works as one coordinated defence.
For homes with active seepage or finished basements at risk, we also design interior perimeter drain systems with sump pumps and backup protection. Every installation is engineered for Montréal's clay soils and freeze-thaw conditions, and backed by our 5-year warranty.
