An interior drainage system intercepts groundwater below your slab before it reaches the visible floor surface, with no excavation and no disrupted landscaping — work done 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 integration, a distinct skill set from exterior excavation.
Active seepage along the wall-floor joint moves to priority scheduling, most Greensboro, NC areas seeing a technician within a day.
Sump basin and pump costs are itemized separately from the drain tile installation itself.
Slab coring is done in a narrow channel along the interior perimeter, with debris containment to keep dust and mess controlled.
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.
Faster to install than full drain tile, and works well for moderate, consistent seepage rather than significant hydrostatic pressure.
We calculate expected inflow volume based on perimeter length and water table before recommending pump horsepower.
Interior systems address this joint directly, capturing water at the source rather than letting it spread across the floor.
Freeze-prone routing is addressed for colder months to prevent winter backup.
Four steps, start to finish — from your call to a finished floor patch over a working drain system.
Active seepage is flagged for priority same-day or next-day scheduling.
Debris containment supplies are brought along in case installation can begin the same visit.
The technician measures affected perimeter length, checks existing sump condition if one exists, and calculates the needed slope.
Interior drainage installations carry a written warranty against seepage failure at the treated perimeter.
What Greensboro, NC customers are saying after their interior drainage system service.
