Drainage Solutions
in West Vancouver, BC
West Vancouver occupies some of the most dramatically sloped residential terrain in Canada, with properties in Horseshoe Bay, Cypress Park, and the higher elevations of the British Properties sitting on terrain that in some cases exceeds 30 degrees. Combined with the North Shore's substantial annual precipitation and the thin, quick-draining soils over bedrock, managing water around foundations in West Vancouver requires careful site-specific engineering rather than standard solutions applied uniformly.
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.

About West Vancouver — What We See Here
The housing stock in West Vancouver ranges from modest post-war homes in Dundarave and Ambleside — many of which have classic 1950s and 1960s crawlspace foundations with the moisture and structural challenges that implies — to very large, high-value custom homes built recently on difficult hillside sites. Both ends of the spectrum require thoughtful crawlspace work, but the implications of getting it wrong differ dramatically. For a modest Ambleside bungalow, a failed encapsulation system means ongoing mold and moisture problems. For a multi-million dollar British Properties estate, it means damage to high-end finishes and systems, and potential liability questions at resale.
We approach West Vancouver crawlspace work with the level of attention to detail that the properties demand. Drainage systems on steep sites must be carefully designed to prevent erosion at discharge points. Structural repairs must account for the additional loads imposed by slope and any retaining walls integrated with the foundation. We work collaboratively with homeowners and, where the project scope warrants it, with structural engineers and landscape architects to ensure drainage systems function as a coordinated whole.
