What "specialized" actually means for interior drainage system at our company — not a marketing word, a set of specific practices.
Proper design accounts for your basement's specific perimeter length and water table depth, not a generic template.
Active seepage along the wall-floor joint moves to priority scheduling, most Harriman, NY areas seeing a technician within a day.
Quotes are priced per linear foot of interior perimeter requiring drain tile, given in writing before any coring begins.
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.
We core the slab along the interior perimeter, set perforated drain tile in washed gravel below the new floor level, and route collected water to a sump basin. 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.
A few quick questions about your basement's finished status help us plan any protective containment needed.
Debris containment supplies are brought along in case installation can begin the same visit.
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.
