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

What "specialized" actually means for interior drainage system at our company — not a marketing word, a set of specific practices.
Certification includes correct slope calculation for the drain channel, which determines whether water actually flows to the sump or just sits.
Crews carry core-cutting equipment and basic drain tile stock, so assessment and the start of installation can often happen on the same visit.
Quotes are priced per linear foot of interior perimeter requiring drain tile, given in writing before any slab coring begins.
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.
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 surface.
This method is faster to install than full drain tile and works well for moderate, consistent seepage rather than significant hydrostatic pressure.
We calculate expected inflow volume based on perimeter length and water table conditions before recommending pump horsepower.
The cove joint where wall meets floor is the single most common seepage point in basements with hydrostatic pressure issues.
Collected water needs to exit the sump basin and the property entirely — we route discharge lines well clear of the foundation with a check valve to prevent backflow into the system.
Here's the exact path from your call to a completed interior drainage install.
Describe the seepage pattern you're seeing — along one wall, around the full perimeter, at specific points — and dispatch routes a crew with the right assessment tools.
Technicians arrive with moisture meters and measuring equipment to calculate exact linear footage before quoting.
The technician measures affected perimeter length, checks existing sump basin condition if one exists, and calculates the slope needed for proper drainage.
Interior drainage installations carry a written warranty against seepage failure at the treated perimeter.
