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.
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 the collected water to a sump basin. 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.
Interior drainage systems address this joint directly, capturing water at the source rather than letting it spread across the floor first.
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.
