Types of Basement Waterproofing Solutions in Seattle
Interior Basement Waterproofing
- Sealants: Waterproof coatings and sealants are applied to basement walls and floors to prevent moisture
- Crack injection: Liquid epoxy or polyurethane is injected into cracks in foundation walls to seal them.
Exterior Basement Waterproofing
- Coating or membrane: A waterproof coating or membrane is applied to the exterior of basement walls.
- Drainage panels: Drainage panels are installed to direct water away from the foundation.
Waterproofing Drainage Systems
- Footing drains :Exterior drainage systems, such as footing drains, divert water away from the foundation.
- Wall Guard/Water Membranes: Membranes that are connected to your wall which funnels any water down to a gravity drainage system.
- Weeping tiles: A network of drainage channels or weeping tiles is installed along the perimeter of the basement floor. We mention these, but we really do not use these much here in the Northwest
- Sump pump installation: Submersible pump (or sump pump) is installed in a pit or sump basin in the basement floor.

Need for Basement Waterproofing Seattle: Top Reasons
- High Water Table: Seattle’s geographical location near Puget Sound and Lake Washington contributes to a relatively high water table, which can cause water to seep into basements.
- Heavy Rainfall: Seattle is known for its significant annual rainfall. This can lead to water accumulation around and under homes, especially if the ground around the foundation is saturated.
- Poor Soil Drainage: Many areas in Seattle have clay soils which do not drain well. This type of soil can hold water against the foundation, leading to moisture intrusion.
- Improper Grading: If the ground around your home slopes towards the foundation rather than away from it, water will naturally flow towards and into the basement.
- Foundation Cracks: Over time, foundations can develop cracks due to settling or seismic activity (Seattle is in an earthquake-prone region), providing pathways for water to enter the basement.
- Lack of or Faulty Gutters and Downspouts: If gutters are clogged or downspouts do not extend far enough away from the house, rainwater can pool next to the foundation, exacerbating basement moisture problems.
- Hydrostatic Pressure: After heavy rains, the pressure from the water-saturated soil can push water through even the smallest cracks in the foundation walls or floor.
- Old or Inadequate Drainage Systems: Older homes might not have modern drainage solutions or the systems might have deteriorated over time, failing to prevent water ingress.
- Sump Pump Issues: If a sump pump (if installed) is not functioning correctly or if there isn’t one where needed, water cannot be effectively removed from around or under the basement.
- Plumbing Leaks: Although not directly related to external water, internal plumbing leaks can contribute to a wet basement, necessitating comprehensive drainage solutions.
