Drainage Solutions
in Burnaby, BC
Burnaby's topography ranges from the relatively flat areas along the Burrard Inlet waterfront through the mid-slope residential neighbourhoods of Capitol Hill and Burnaby Mountain to the lower-lying districts around Edmonds and Metrotown. The variability in elevation and soil conditions means crawlspace challenges vary considerably across the city. Properties on Burnaby Mountain and Capitol Hill often deal with steep-site drainage challenges, where surface water moving downslope through clay soils is channelled toward downhill foundation walls. Properties near Deer Lake and in the lower Edmonds area face a higher seasonal water table.
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 Burnaby — What We See Here
Many of Burnaby's established residential neighbourhoods were built in the post-war era through the early 1970s, and a significant proportion of this housing stock has crawlspace foundations. These homes are now old enough that original structural wood — posts, beams, sill plates — has had decades of exposure to whatever moisture conditions were present before the first renovations or repairs were done. In our experience, Burnaby homes from this era are among the most likely to have multiple compounding issues: deteriorated original posts, collapsed insulation, and mold on the subfloor underside that has gone unnoticed for years.
The good news for Burnaby homeowners is that the soil conditions in most of the city, while clay-heavy, respond well to proper perimeter drainage improvements. Combined with encapsulation, these interventions tend to produce very effective results. We also note that Burnaby has an active real estate market, and crawlspace conditions are increasingly part of pre-sale and pre-purchase inspection discussions — a clean, documented, encapsulated crawlspace is a measurable asset in the market.
