Drainage Solutions
in Maple Ridge, BC
Maple Ridge sits at the base of the Coast Mountains on the north bank of the Fraser River, with residential development spanning from the flat benchland near the river up into increasingly steep terrain toward the mountain front. The community receives significant precipitation — positioned to catch heavy orographic rainfall from Pacific systems moving against the mountain barrier — and the soils in the lower agricultural fringe areas that have been converted to residential use are often poorly drained organic-clay mixes that stay saturated for extended periods in winter.
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 Maple Ridge — What We See Here
The Hammond area near the river and the Haney town centre core have the oldest residential stock in Maple Ridge, with some homes dating to the early 1900s. Crawlspaces in these homes have weathered nearly a century of Maple Ridge winters, and original structural elements have often been repaired multiple times. We look carefully at the bearing condition of all structural members in these older homes — not just whether they look sound visually, but whether the footings they rest on are still at grade and providing adequate support.
Silver Valley and the newer uphill developments have a different profile: homes built in the 2000s and 2010s on steeply sloped lots where construction required significant cut-and-fill grading. When fill is placed against a foundation and not adequately drained or compacted, it can direct surface water toward the crawlspace for years after the home is occupied. We see this pattern in a number of newer Maple Ridge homes, and the fix is typically an exterior perimeter drain system that intercepts water before it reaches the foundation wall.
