A properly installed interior perimeter drain system intercepts groundwater at the slab edge and routes it to a sump basin before it ever reaches your floor.
Not every Dundee, OR basement needs full-perimeter drain tile — sometimes a targeted section addressing the actual entry point is the more cost-effective, equally durable fix. We size the scope to what the inspection actually shows.
Every technician is trained specifically on interior drain tile layout, slope, and tie-in to the sump system.
Interior drainage installs are scheduled locally, without routing through a national call center that adds weeks to the timeline.
Sump basin and pump costs are itemized separately so you can see exactly what makes up the total.
Every system is tested with a hose before we consider the install complete.
Every Dundee, OR Interior Drainage System job starts with an inspection, not a generic package — here's what that typically includes.
A channel is cut along the slab edge, perforated pipe is laid with proper slope, and gravel backfill allows water to flow freely into the drain.
Basin placement is chosen for the shortest, most direct discharge path away from the foundation.
This option works well as a lower-disruption alternative to full perimeter drain tile in certain Dundee, OR basement layouts.
The cove joint where wall meets floor is sealed and tied directly into the drain system so water is captured right at the entry point.
Existing drain tile that's clogged with silt or has failed slope can often be cleaned or repaired rather than fully replaced.
This helps us bring the right materials and estimate linear footage before the visit.
We also check existing drainage, if any, to determine whether repair or new installation makes more sense.
You'll see drain tile footage, basin specs, and any cove joint work broken out in the written estimate.
Most residential interior drainage installs finish in one to three days depending on perimeter length.
"Water was coming in along one wall every heavy rain. They installed targeted drain tile just on that section instead of charging us for the whole perimeter."
— Dundee Homeowner
"Cove joint had been the source of our leak for years and nobody had addressed it until now."
— Dundee Customer
"Explained the slope requirements in a way that actually made sense, not just technical jargon."
— Dundee Homeowner
"Clean install, patched concrete matched the existing floor color almost perfectly."
— Dundee Customer
Full perimeter systems make sense when multiple walls show signs of intrusion or as preventive coverage.
We'll recommend whichever fits your basement's finish level and budget.
{Sometimes — if the pipe itself is intact but clogged with silt, cleaning can restore function without a full re-installation.|We camera-inspect where accessible to make that determination before recommending replacement.}
An undersized basin cycles the pump too often, so we don't cut corners on sizing.
Cutting the slab does involve some disruption, but we work in sections and clean up debris as we go.
We give you a realistic timeline in the written quote based on your specific basement layout.
