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.
No hourly billing — if scope changes once the slab is opened, we discuss it before proceeding.
We coordinate installation to minimize disruption to finished basement spaces wherever possible.
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.
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 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.
Describe the seepage pattern — along one wall, around the full perimeter, at specific points — and dispatch routes a crew with the right assessment tools.
Debris containment supplies are brought along in case installation can begin the same visit.
You'll see the full installation plan explained, including where the new floor patch will meet the existing slab.
The completed system is tested by verifying flow to the sump basin before the floor patch is finished and the crew leaves.
