Groundwater & Basement Water Intrusion in Olympia, WA
Basement seepage, failed sumps and water through the slab are extracted and dried, and the path from the ground is found so the floor stays dry next season. The path from the ground is named first: through the wall, up through the slab, back through a drain, or from a sump that stopped. The space is extracted and dried, with the porous materials the water touched removed, and the delivery is addressed, because a dried floor only stays dry if the water stops arriving.

Often needed alongside
- Structural Drying & Dehumidification
Sealed air movers and dehumidifiers bring framing, subfloor and drywall back to a measured dry standard, with daily readings logged from inside the material.
- Emergency Water Extraction
Standing water is pumped and extracted around the clock, before it climbs the walls and soaks the subfloor. Same-day response where coverage allows.
- Mold Inspection & Testing
An independent assessor confirms whether the assembly that got wet is actually dry, whether growth started while it was not, and how far it reaches.
Frequently asked questions
What is under the downtown?
Fill placed over what were tidal flats, and beneath that a confined aquifer. The water in that aquifer is under pressure, which is why there are artesian wells here that flow without pumping, and it is pressing up under the fill.
Does that change what a sump is doing?
It changes what it is fighting. A pump dealing with rain that has soaked down eventually wins; one dealing with water being pushed up from below is working against a source that does not stop, so it runs continuously rather than cycling.
How can the two be told apart?
By when it runs. Surface water follows the rain with a delay of hours to days; artesian pressure is steady and largely indifferent to the weather. A sump that runs just as hard in August as in November is telling you which it is.
