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.
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.
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.
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.
Every interior drainage system needs a properly sized sump basin and pump at its endpoint — undersizing this component undermines the whole system regardless of how well the drain tile itself is installed.
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.
Four steps, start to finish — from your call to a finished floor patch over a working drain system.
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.
We schedule a follow-up check after the next significant rain to confirm the system is performing as designed.
