Restaurant Drainage, Floor Drains & Waterproofing — Metro Vancouver

Restaurants combine grease-loaded kitchen drainage, walk-in cooler condensate, patio runoff and — in many Lower Mainland buildings — a basement prep or storage area below the water table. Downtime is expensive, so work is usually staged overnight or between services.

What goes wrong on restaurants

Slow or backing-up floor drains

Grease, food solids and scale build up in kitchen lines and interceptors, then back up through floor drains during the busiest service.

Wet basements and prep areas

Below-grade storage, walk-ins and prep rooms need dry, health-inspection-ready floors and walls year round.

Patios and rear service areas

Poorly drained patios, loading zones and grease bin pads send water straight back at the building.

Rain runs off the roof, into the leaders, down through drain rock to the perimeter drain, then out to the storm connection or sump — keeping water off the foundation wall.

Frequently asked questions

Can drainage work be done outside service hours?

Yes. Kitchen floor drain, interceptor line and trench drain work is routinely staged overnight or between services so the restaurant does not close.

How often should grease-loaded lines be jetted?

Most Lower Mainland kitchens hold up well on a quarterly hydro jetting schedule; high-volume kitchens often move to monthly interceptor service.

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.
