What goes wrong on retail & shopping centres
Ponding in the parking lot
Settled asphalt and blocked catch basins create standing water, ice hazards and liability at entrances.
Water tracking into tenant units
Storefront thresholds and rear service doors let sheet runoff into leased space when surface drainage fails.
Deferred storm maintenance
Catch basin sumps, storm laterals and oil interceptors on retail sites need scheduled cleaning to keep working.

Frequently asked questions
Can parking lot drainage be repaired in stages?
Yes — catch basins and storm laterals are usually done zone by zone overnight so customer parking and delivery access stay open.
Who is responsible, landlord or tenant?
It depends on the lease, but site storm drainage and building envelope items are typically landlord scope. A written scope and camera report helps settle it quickly.
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.
