Drainage Solutions
in Port Moody, BC
Port Moody occupies the eastern tip of Burrard Inlet, with residential development largely on the steep slopes rising above the waterfront. This geography creates a very specific drainage situation: water moving downslope through the thin glacially-derived soils reaches the residential areas quickly during heavy rain events, and properties on the lower slopes can experience significant lateral water pressure against uphill foundation walls. The marine proximity adds ambient humidity even on dry days, and the inlet's position means marine fog is a common morning condition through much of the year.
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 Port Moody — What We See Here
Homes in the established College Park and Glenayre neighbourhoods are primarily from the 1960s and 1970s, with crawlspace foundations that have dealt with these conditions for decades. The sloped sites in these areas create natural opportunities for gravity drainage improvements that we can take advantage of — a properly graded perimeter drain routed to daylight on the low side of the property can be very effective here without requiring a sump pump. We assess each site's specific topography to determine whether gravity or mechanical drainage is the right approach.
The newer developments around Newport Village and the inlet waterfront area are generally more modern construction on concrete slabs, so crawlspace work in Port Moody tends to be concentrated in the older hillside neighbourhoods. Heritage-era homes near St. Johns Street and the original townsite occasionally have older construction techniques that need to be understood before any crawlspace intervention is planned.
