What "specialized" actually means for interior drainage system at our company — not a marketing word, a set of specific practices.
Technicians are specifically trained in slab coring, drain tile installation, and sump basin integration — a distinct skill set from exterior excavation work.
Active seepage along the wall-floor joint moves to priority scheduling — most Piney Flats, TN 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.
Because the work stays entirely inside, there's no landscaping disruption, no exterior excavation permit needed in most jurisdictions, and typically a faster completion timeline than exterior alternatives.
Each service below is scoped specifically to interior drainage system, not a generic waterproofing menu with the name swapped in.
We core the slab along the interior perimeter, set perforated drain tile in washed gravel below the new floor level, and route the collected water to a sump basin. 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.
We calculate expected inflow volume based on perimeter length and water table conditions before recommending pump horsepower.
Interior drainage systems address this joint directly, capturing water at the source rather than letting it spread across the floor first.
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.
