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.
Active seepage along the wall-floor joint moves to priority scheduling — most Holt, MI areas see a technician within a day.
No hourly billing — if the job scope changes once the slab is opened, we discuss it with you before proceeding.
Because the work stays entirely inside, there's no landscaping disruption, no exterior excavation permit needed in most jurisdictions, 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.
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.
A few quick questions about your basement's finished versus unfinished status help us plan for any protective containment needed.
Technicians arrive with moisture meters and measuring equipment to calculate exact linear footage before quoting.
Pricing is itemized per linear foot for drain tile plus sump basin and pump costs, in writing before coring begins.
The completed system is tested by verifying flow to the sump basin before the floor patch is finished and the crew leaves.
