Groundwater & Basement Water Intrusion in Eugene, OR
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
There is no standing water under the house but the crawl space smells.
That is the characteristic local problem and it is a vapor issue rather than a flooding one. Through the winter the ground under the house stays close to saturated, and moisture evaporates continuously from the soil into the crawl space and then into the framing and the house above. There may never be water to pump out. A well-sealed ground vapor barrier addresses this far more effectively than ventilation, which in a wet winter simply brings in more damp air.
Why do problems here take months to show up?
Because the rain is steady rather than dramatic. Seven inches spread across December keeps everything continuously damp without ever producing an event, so the wood under the floor gains moisture week by week and there is no single incident to notice. By the time a smell or a soft floor appears, the condition has usually been present for a season or more. Checking the crawl space in February, when the ground is at its wettest, tells you more than checking in August.
Do gutters matter much in a place with this little intense rain?
They matter for a different reason than in a stormy climate. Here the issue is duration: a blocked downspout concentrates roof runoff onto one spot of foundation soil continuously for months, not for an afternoon. Combined with heavy autumn leaf fall, gutters block early in the wet season and stay blocked through it. Clearing them in November is one of the highest-value maintenance tasks in this climate.
