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.
Services for parking garages
Drain Tile for parking garages
Parkade structures rely on a perimeter drain at footing level; when it silts up, water pressure moves straight to the walls and slab.
Basement Waterproofing for parking garages
Parkade waterproofing includes crack and cold-joint injection, negative-side coatings, wall membranes and traffic-deck membrane repair.
Drainage for parking garages
Parkade drainage means ramp trench drains, slab area drains, oil-water separators, and duplex sump systems with alarms and backup power.

Frequently asked questions
Why does the parkade flood at the ramp?
Ramp trench drains catch street and roof runoff. When they are undersized, silted or connected to an overloaded storm line, water sheets straight down into the structure.
What sump setup does a parkade need?
Duplex pumps with alternating operation, a high-water alarm and backup power are the standard for below-grade structures in BC.
How much does commercial drainage or waterproofing work cost in BC?
Commercial pricing depends on depth, access, length of perimeter and how much of the site has to stay open during the work. Most contractors scope from a camera inspection first, then price by section. Quotes through DRYHOMEBC are free and carry no obligation.
How fast can someone attend an active flood?
Send the request with 'urgent' in the details and we push it to crews with emergency capacity in your city — most respond the same or next business day, and pump-out or temporary bypass work can usually start immediately.
