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.
Ongoing seepage means every day without a fix is another day of potential damage.
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 collected water to a sump basin. 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.
The cove joint where wall meets floor is the most common seepage point in basements with hydrostatic pressure issues.
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.
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 Hewlett, NY assessments are scheduled within a day or two given the priority nature of active seepage.
The technician measures affected perimeter length, checks existing sump condition if one exists, and calculates the needed slope.
We schedule a follow-up check after the next significant rain to confirm performance.
