Why commercial buildings need this work
Drainage work moves water away from the building and off the property. On Lower Mainland lots — clay soils in Surrey, delta silt in Richmond and Delta, slopes in Coquitlam and Port Moody — the right system depends entirely on where the water comes from and where it can legally go.
Water in lower levels and elevator pits
Hydrostatic pressure against below-grade walls and pit slabs is the most common commercial call in BC, usually traced back to a silted perimeter drain or a failed pit pump.
Storm connections at capacity
Large roof areas, parking surfaces and added hardscape overload storm laterals installed for a smaller original footprint.
Working around tenants
Commercial work is planned around business hours, parking access, fire lanes and traffic management — ask every bidder how they will stage the site.
