Exterior basement waterproofing prevents groundwater from ever reaching your foundation walls by excavating around the perimeter, applying a robust waterproof membrane, installing drainage components, and regrading the soil. This approach tackles leaks at their source—unlike interior fixes that manage water only after it enters the basement.
St. Catharines’s unique conditions make basements vulnerable::
● High Water Table Near Lake Ontario & Twelve Mile Creek: Groundwater often sits within inches of your footing.
● Lake-Effect Precipitation & Spring Thaw : Sudden downpours—especially near Port Dalhousie and Merritton—can overload soils.
● Clay & Silt Soils: Locally, heavy clay retains moisture, increasing hydrostatic pressure against walls.
● Freeze–Thaw Cycles: Winter temperatures cause water in foundation materials to freeze and expand, widening cracks over time.
An exterior foundation waterproofing St. Catharines system provides the strongest defense, preserving both structure and interior finishes.
