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.
Technicians are specifically trained in slab coring, drain tile installation, and sump basin integration — a distinct skill set from exterior excavation work.
We understand ongoing seepage means every day without a fix is another day of potential damage to flooring and stored belongings.
Quotes are priced per linear foot of interior perimeter requiring drain tile, given in writing before any slab coring begins.
Slab coring is done in a narrow channel along the interior perimeter, with debris containment to keep dust and mess controlled during installation.
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.
Where full slab coring isn't practical or budget allows for a lighter-scope fix, a baseboard-mounted channel system captures water at the wall-floor joint and routes it to a discharge point.
We calculate expected inflow volume based on perimeter length and water table conditions before recommending pump horsepower.
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.
Here's the exact path from your call to a completed interior drainage install.
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.
Technicians arrive with moisture meters and measuring equipment to calculate exact linear footage before quoting.
The technician measures affected perimeter length, checks existing sump basin condition if one exists, and calculates the slope needed for proper drainage.
The completed system is tested by verifying flow to the sump basin before the floor patch is finished and the crew leaves.
What Aurora, IL 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."
