Basement Waterproofing

Protect your basement from leaks, flooding, and dampness. We install advanced interior and exterior waterproofing systems to redirect water away from your foundation and keep your basement dry.

Common solutions include: Interior drainage channels & sump pump systems, exterior waterproof membranes & weeping tile replacement, moisture barrier and vapour sealing for finished basements

Foundation Crack Repair

Stop leaks and structural cracks before they spread. We repair vertical, horizontal, and floor cracks using professional injection systems (epoxy and polyurethane) to restore integrity and prevent water intrusion. Ideal for: Seepage through cracks after heavy rain Settlement cracks in poured concrete walls Leaking cold joints or wall–floor intersections

Our methods include: Wall anchors and tie-backs for bowing walls, helical piers and underpinning for settling foundations, slab jacking and leveling for uneven floors

Turn your crawl space into a clean, dry, healthy environment. We install heavy-duty vapour barriers, insulation, and dehumidification systems to control moisture, improve energy efficiency, and eliminate mold risk.
