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.
Technicians are specifically trained in slab coring, drain tile installation, and sump basin integration — a distinct skill set from exterior excavation work.
Crews carry core-cutting equipment and basic drain tile stock, so assessment and the start of installation can often happen on the same visit.
Sump basin and pump costs are itemized separately from the drain tile installation itself.
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.
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.
Here's the exact path from your call to a completed interior drainage install.
A few quick questions about your basement's finished versus unfinished status help us plan for any protective containment needed.
Technicians arrive with moisture meters and measuring equipment to calculate exact linear footage before quoting.
Pricing is itemized per linear foot for drain tile plus sump basin and pump costs, in writing before coring begins.
The completed system is tested by verifying flow to the sump basin before the floor patch is finished and the crew leaves.
