Parkade Drainage, Sump Systems & Waterproofing — Lower Mainland BC

An underground parkade is a concrete box below the water table. Everything depends on ramp trench drains, the perimeter drain around the structure, and pumps that never get to fail. Standing water, efflorescence and rebar staining are all early warnings.

What goes wrong on parking garages

Ramp and entry flooding

Undersized or blocked ramp trench drains let street and roof runoff pour down into the parkade during heavy rain.

Sump and pump reliability

Duplex pumps, high-water alarms and backup power are what stand between a working parkade and an insurance claim.

Slab and wall leaks

Cracks, cold joints and failing traffic-deck membranes drip onto vehicles and accelerate rebar corrosion.
