An interior drainage system intercepts groundwater below your slab before it ever reaches the visible floor surface — no excavation, no disrupted landscaping, work completed entirely from inside.

Four commitments that separate a properly trained interior drainage system crew from a generalist showing up with a truck and a hope.
Proper interior drainage design accounts for your basement's specific perimeter length and water table depth, not a generic template.
Active seepage along the wall-floor joint moves to priority scheduling — most Rochester, WA areas see a technician within a day.
No hourly billing — if the job scope changes once the slab is opened, we discuss it with you before proceeding.
We coordinate installation to minimize disruption to finished basement spaces wherever possible.
We don't run a one-size-fits-all playbook — every interior drainage system job starts from these core service components, adapted to what your property actually needs.
The channel is sloped precisely toward the discharge point so water flows by gravity rather than pooling within the drain tile itself. New concrete is poured back over the channel, restoring a finished, level floor surface.
This method is faster to install than full drain tile and works well for moderate, consistent seepage rather than significant hydrostatic pressure.
Every interior drainage system needs a properly sized sump basin and pump at its endpoint — undersizing this component undermines the whole system regardless of how well the drain tile itself is installed.
The cove joint where wall meets floor is the single most common seepage point in basements with hydrostatic pressure issues.
Collected water needs to exit the sump basin and the property entirely — we route discharge lines well clear of the foundation with a check valve to prevent backflow into the system.
Four steps, start to finish — from your call to a finished floor patch over a working drain system.
Describe the seepage pattern you're seeing — along one wall, around the full perimeter, at specific points — and dispatch routes a crew with the right assessment tools.
Debris containment supplies are brought along in case installation can begin the same visit.
Pricing is itemized per linear foot for drain tile plus sump basin and pump costs, in writing before coring begins.
Interior drainage installations carry a written warranty against seepage failure at the treated perimeter.
What Rochester, WA customers are saying after their interior drainage system service.
"No more water creeping across the floor every time it rains hard. The drain tile handles it now before it ever reaches the surface."
"Appreciated that they explained the slope calculation — made it clear this wasn't just a drain thrown in randomly."
"Floor patch after the coring work is seamless, you'd never know they'd opened up the slab."
"Whole install was done in about a day and a half with minimal mess given they were cutting into concrete."
