Groundwater & Basement Water Intrusion in Aberdeen, WA
Basement seepage, failed sumps, and hydrostatic pressure against the foundation are extracted and dried, and the path from the ground is identified so the loss does not repeat. Groundwater and basement seepage are extracted and dried only after the path from the soil is identified — a wall, a slab, a drain, or a failed sump. Drying the interior without stopping that path returns the same water to the same floor.
Frequently asked questions
Does anything ever dry out here between November and March?
Not really, and that is the single most important thing to design around. With this much rain arriving continuously, materials do not get a dry interval, so a small defect runs all winter instead of drying between events. It also means outdoor air offers no drying help at all: opening a building up in January adds moisture. Every drying job here has to be a closed system with mechanical dehumidification.
Why do some January storms flood us and bigger ones do not?
The tide. Rainfall here has to discharge into water whose level the tide sets, so a moderate storm arriving on a high tide can do more than a larger one that arrives on a falling tide. The rivers back up rather than carrying flow away. Checking the tide table alongside the forecast is not a refinement here; it is the main variable.
Is there any point in gutters and grading in a place this wet?
Yes, and for a different reason than in a drier climate. Nothing you do at the lot will handle eighty-five inches, but keeping roof water controlled and moving away from the building reduces how much of the year the foundation soil is fully saturated. That is the difference between a crawl space that is damp and one that has standing water. It is a matter of degree rather than a fix, and the degree matters.
