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.

What "specialized" actually means for interior drainage system at our company — not a marketing word, a set of specific practices.
Proper interior drainage design accounts for your basement's specific perimeter length and water table depth, not a generic template.
We understand ongoing seepage means every day without a fix is another day of potential damage to flooring and stored belongings.
No hourly billing — if the job scope changes once the slab is opened, we discuss it with you before proceeding.
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.
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.
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 across Fletcher, NC.
Debris containment supplies are brought along in case installation can begin the same visit.
Pricing is itemized per linear foot for drain tile plus sump basin and pump costs, in writing before coring begins.
We schedule a follow-up check after the next significant rain to confirm the system is performing as designed.
