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.

What "specialized" actually means for interior drainage system at our company — not a marketing word, a set of specific practices.
Correct slope calculation determines whether water actually flows to the sump or just sits.
Crews carry core-cutting equipment and basic drain tile stock, so assessment and installation often start the same visit.
Sump basin and pump costs are itemized separately from the drain tile installation itself.
Because work stays entirely inside, there's no landscaping disruption 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 collected water to a sump basin. 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.
Every interior system needs a properly sized sump basin and pump at its endpoint — undersizing this undermines the whole system regardless of drain tile quality.
The cove joint where wall meets floor is the most common seepage point in basements with hydrostatic pressure issues.
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.
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.
Technicians arrive with moisture meters and measuring equipment to calculate exact linear footage before quoting.
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.
