Drainage Solutions
in Bridgeview, BC

Bridgeview is a mixed residential and light-industrial neighbourhood in north Surrey, sitting adjacent to the Alex Fraser Bridge approach and close to the Fraser River. The area occupies low-lying ground with a water table profile similar to Newton and parts of Richmond — close to grade through the wet season and subject to periodic flooding during major rain events or high freshet years. Many of the residential homes in Bridgeview are older properties on larger lots, some dating from the 1950s and 1960s, with crawlspaces that have had decades of exposure to these demanding conditions.

Drainage problems in crawlspaces have two distinct origins: water that arrives from outside (surface runoff, failed exterior drainage, high water table) and water that condenses from the air inside the crawlspace onto cooler surfaces. The solutions for each are different, and correctly diagnosing which problem you have — or which combination — is the critical first step. Applying interior drainage solutions to an exterior water problem provides partial relief at best; addressing the exterior source is far more effective and usually less disruptive.

Interior drainage systems — perimeter drain tile installed inside the crawlspace along the base of the stem wall — are the right solution when exterior work is impractical (due to finished landscaping, hardscaping, or very tight site conditions) or when the primary issue is groundwater rising from below rather than surface water entering through the wall. Interior drain tile channels water to a sump pit where a pump removes it. This approach does not stop water from entering the foundation, but it manages it effectively once it does.
