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.
Proper interior drainage design accounts for your basement's specific perimeter length and water table depth, not a generic template.
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.
Each service below is scoped specifically to interior drainage system, not a generic waterproofing menu with the name swapped in.
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.
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.
Debris containment supplies are brought along in case installation can begin the same visit.
Pricing is itemized per linear foot for drain tile plus sump basin and pump costs, in writing before coring begins.
We schedule a follow-up check after the next significant rain to confirm the system is performing as designed.
