How We Find and Fix Basement Leaks
Our certified technicians start with a thorough visual inspection of your basement walls, floor, and cove joint (where the floor meets the wall). We identify the source — whether it's a crack, porous block, failed parging, or the cove joint — and recommend the right solution. We use high-grade epoxy or polyurethane injection for structural cracks, which expands to fill the crack completely and bonds to the concrete permanently.
Why Basement Leaks Get Worse Over Time
Water damage is progressive. A small crack that lets in a trickle during spring rains will grow year after year as freeze-thaw cycles expand the opening. Moisture leads to mould, damage to finishes, and deterioration of your foundation's structural integrity. Fixing it early is always cheaper and less disruptive than waiting.
Interior vs. Exterior Leak Repair
Interior repair methods (crack injection, drain tile systems) can be done without excavation and are ideal for most leaking basements. Exterior waterproofing is the most permanent solution — we excavate to the footing, apply a waterproof membrane, and install new weeping tile — but is reserved for severe cases or when full foundation protection is needed.
