Wet Basement in Seattle?

Waterproofing a basement in Seattle is a complex undertaking, and issues with wet basements are commonly linked to factors such as a high water table, inadequate landscaping, gutters lacking extensions, subpar concrete floors, or the absence of a drainage tile system connected to a sump pump, either inside or outside the footings.

Seattle’s unique climate and the prevalence of rain make it imperative to address these concerns promptly and effectively.

When dealing with a wet basement in Seattle, start by inspecting the slope of the soil around your home. It is crucial that the dirt slopes away from the house for the first ten feet, including any recent landscaping modifications. Additionally, assess the condition of your gutters. Ensure they are present, directing water several feet away from the house. It’s important that they can be trimmed but not removed. Ideally, the gutters should channel water at least the first five feet away from your home.

Consider the installation of a drainage system, either inside or outside, to mitigate water-related issues. Each option has its advantages and drawbacks, with external systems allowing the application of various membranes and coatings to the foundation. An exterior drainage tube, properly situated in a gravel-filled trench and covered with fabric and gravel during backfilling, can be a valuable solution. On the other hand, an internal system may involve drilling weep holes in concrete blocks for water drainage. Regardless of the approach, both systems require a sump and a sump pump to ensure effective water removal in Seattle’s wet conditions.
