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 integration, a distinct skill set from exterior excavation.
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.
Because work stays entirely inside, there's no landscaping disruption and typically a faster completion timeline than exterior alternatives.
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.
Faster to install than full drain tile, and works well for moderate, consistent seepage rather than significant hydrostatic pressure.
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.
Freeze-prone routing is addressed for colder months to prevent winter backup.
Here's the exact path from your call to a completed interior drainage install.
Active seepage is flagged for priority same-day or next-day scheduling.
Technicians arrive with moisture meters and measuring equipment to calculate exact linear footage before quoting.
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.
