Drain Tile for Parking Garages & Parkades — Lower Mainland BC

Parkade structures rely on a perimeter drain at footing level; when it silts up, water pressure moves straight to the walls and slab.

Why parking garages need this work

Drain tile — the perforated pipe buried at the base of your foundation footing — is the single most important defence a Lower Mainland home has against groundwater. Original clay and concrete tile installed before the 1970s eventually collapses, fills with silt, or is choked by roots. These are the four jobs local contractors are called out for most.

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.
