Basement Waterproofing in Lakewood, WA

Basement waterproofing in Lakewood: what to know

Start with the ground: gravelly outwash rarely holds water against a wall for long. When a basement or crawlspace is wet anyway, the cause is usually local. Roof water released at the foundation, soil graded toward the house, window wells that fill, a clogged footing drain, or a leaking pipe are all likelier culprits than the soil itself.

The exceptions are lake and creek edges. American and Gravelly Lakes are fed by groundwater, Gravelly Lake has no surface inlet, and its gauge has recorded swings of about 11 feet, so a house low on the shore can see the water table rise in wet years. The city also says a 100-year flood on Clover Creek could reach properties in the Springbrook and Hillside neighborhoods.

Permits and rules in Lakewood

Sealing and regrading often need no permit, but the city’s handout says repairs to drain leader piping are not ordinary repairs and may need review, and digging near a property line, utility, or critical area can too. In mapped flood areas the flood overlay treats a basement as the lowest floor for new construction and substantial improvement. Foundation water generally cannot go to the sanitary sewer. We confirm requirements before we quote.

Rules change and vary by parcel, so we confirm the current requirements with the city before we start.

How we approach it

Trace the water: downspouts, grade, window wells, plumbing, then the footing drain
Compare the dampness against recent lake and creek levels
Check for abandoned septic parts before excavating beside the house
Settle the outlet first so drained water has a legal place to go

Questions from Lakewood homeowners

My Lakewood crawlspace is damp but the soil here drains. What causes it?

Usually water entering from above or beside: downspouts, grade, a clogged footing drain, a plumbing leak, or humid air with no vapor barrier. Free-draining soil lowers the odds of standing groundwater but not lake-level effects near the shore. We trace the source first.

Do lake levels affect Lakewood basements near American or Gravelly Lake?

They can. Both lakes are groundwater-fed, and Gravelly Lake has no surface inlet, so the water table beside them follows wet and dry years. A basement low on the shore may see seepage when the lake is high. That calls for drainage, sometimes a sump, not a surface patch.

My Lakewood house is from the 1960s. Could an old septic system be near the foundation?

Possibly. Pierce County built sewers through the Lakewood Water District area from 1981 to 1984, so many earlier houses began on septic. An abandoned tank or drain line can remain on a lot and must be located before excavation.
