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 integration, a distinct skill set from exterior excavation.
Ongoing seepage means every day without a fix is another day of potential damage.
Quotes are priced per linear foot of interior perimeter requiring drain tile, given in writing before any coring begins.
Because work stays entirely inside, there's no landscaping disruption 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 collected water to a sump basin. New concrete is poured back over the channel, restoring a finished, level floor.
Where full slab coring isn't practical, 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 before recommending pump horsepower.
Interior systems address this joint directly, capturing water at the source rather than letting it spread across the floor.
Collected water needs to exit the sump basin and property entirely — we route discharge well clear of the foundation with a check valve to prevent backflow.
Here's the exact path from your call to a completed interior drainage install.
A few quick questions about your basement's finished status help us plan any protective containment needed.
