Basement Waterproofing

While Calgary's semi-arid climate means less rainfall than many Canadian cities, basement waterproofing remains essential due to spring snowmelt cycles that can saturate soil and drive hydrostatic pressure against foundation walls. Calgary's frost depth extends beyond 1.2 metres, meaning exterior waterproofing and drainage systems must be installed below this depth to function properly and avoid frost heave damage.

Our exterior waterproofing services include excavation to the foundation footing, application of rubberized membrane coatings, installation or replacement of weeping tile drainage systems, and backfill with free-draining gravel. This comprehensive approach addresses water at the source before it can enter your basement.

Interior waterproofing solutions are often more practical for Calgary homeowners, particularly in established inner-city neighbourhoods where exterior excavation is complicated by landscaping, driveways, or adjacent structures. We install interior perimeter drainage channels that collect water seeping through wall-floor joints and direct it to a sump pump system for discharge.

Sump pumps are equipped with battery backup systems to maintain protection during Calgary's occasional power outages from summer storms. Foundation crack repair using epoxy or polyurethane injection seals active leaks from the inside without excavation. We also address efflorescence and mineral deposits on foundation walls, which are common indicators of moisture migration through Calgary's concrete foundations.

Every waterproofing project includes a thorough assessment of grading, downspout discharge, and window well drainage to ensure surface water is managed effectively alongside the foundation-level work.
