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 Occoquan, VA areas seeing a technician within a day.
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.
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.
A few quick questions about your basement's finished status help us plan any protective containment needed.
Technicians arrive with moisture meters and measuring equipment to calculate exact linear footage before quoting.
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.
