Basement Waterproofing & Foundation Drainage

Engineered Hydrostatic Pressure Relief

Sarnia's high lakefront water table and dense clay soil generate extreme hydrostatic pressure against foundation walls. We engineer permanent drainage barriers rather than applying temporary cosmetic interior sealants:

• Exterior Foundation Excavation: Full excavation to footers, high-pressure polyurethane crack injection, seamless rubberized elastomeric membrane, and dimpled drainage air-gap board.
• Perforated Weeping Tile & Stone Envelope: Continuous weeping tile wrapped in geotextile filter fabric and surrounded by clean drainage stone.
• Interior French Drains: Sub-slab perimeter drainage channels tied directly to sealed sump pits when exterior property access is blocked.
• Fail-Safe Sump Systems: High-output cast-iron primary pumps paired with dual marine battery emergency backup systems to ensure continuous pumping during severe storm power outages.
