Drainage Solutions
in Hammond, BC
Hammond is one of the oldest settled communities in Maple Ridge, located near the Pitt River and the Fraser River confluence. The flat bottomland position means water management is a significant concern — the area was historically prone to flooding before modern dyke systems were established, and the water table remains high through the wet season. Older homes in Hammond have dealt with challenging moisture conditions for decades, and many have accumulated significant crawlspace damage as a result.
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 Hammond — What We See Here
The proximity to the river means that Hammond homes should be designed for worst-case water table conditions, not average conditions. We size sump systems here to handle peak spring freshet conditions when both rivers run high and groundwater across the floodplain rises correspondingly. This larger-capacity approach costs marginally more upfront but provides the margin of safety that the location demands.
