An interior drainage system intercepts groundwater below your slab before it reaches the visible floor surface, with no excavation and no disrupted landscaping — work done entirely from inside.

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.
Active seepage along the wall-floor joint moves to priority scheduling, most Islandia, 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.
Slab coring is done in a narrow channel along the interior perimeter, with debris containment to keep dust and mess controlled.
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.
We calculate expected inflow volume based on perimeter length and water table before recommending pump horsepower.
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 Islandia, 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.
Interior drainage installations carry a written warranty against seepage failure at the treated perimeter.
