Four commitments that separate a properly trained interior drainage system crew from a generalist showing up with a truck and a hope.
Correct slope calculation determines whether water actually flows to the sump or just sits.
Ongoing seepage means every day without a fix is another day of potential damage.
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.
Each service below is scoped specifically to interior drainage system, not a generic waterproofing menu with the name swapped in.
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.
Where full slab coring isn't practical, a baseboard-mounted channel system captures water at the wall-floor joint and routes it to a discharge point.
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.
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.
Four steps, start to finish — from your call to a finished floor patch over a working drain system.
Describe the seepage pattern — along one wall, around the full perimeter, at specific points — and dispatch routes a crew with the right assessment tools.
Most Marlton, NJ assessments are scheduled within a day or two given the priority nature of active seepage.
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.
