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.
Certification includes correct slope calculation for the drain channel, which determines whether water actually flows to the sump or just sits.
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.
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.
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.
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.
A few quick questions about your basement's finished versus unfinished status help us plan for any protective containment needed.
