The job: 150 feet of interior drainage

This Macomb Township basement got a full interior drainage system along 150 linear feet of wall, designed to keep the basement dry.

Why an interior drainage system works

A full interior drainage system collects water at the footing, where it gets in, and carries it to the sump pump so it never reaches the floor.

How we built it, in three videos

Day 1: breaking out the floor. We broke out the basement floor along the walls and prepped the walls for the drainage system.

Part 2: trenching along the foundation. With the slab cut, we opened the trench along the foundation walls so the drain tile and stone could go in.

Part 3: the finished system. All 150 feet of interior drainage in place, with proper pitch to the sump.

The result

A finished 150-foot interior drainage system: clean work, proper pitch and solid protection against water coming in. The waterproofing system is backed by our 25-year transferable limited warranty. The warranty doesn’t cover the sump pit or the pump.

Frequently Asked Questions

To reach the footing. We break out the floor along the walls and dig the trench down to the footing, because that’s where the water gets in and where the drain tile has to sit.

The drain tile is laid on a slope toward the sump, so the water it collects flows to the sump pump instead of sitting in the pipe.

Interior waterproofing with drain tile, membrane and a sump runs about $2,000 to $35,000. The biggest factor is how much wall needs it, so a 150-foot system costs more than a single wall. Estimates are free. See the cost guide.

The waterproofing system carries our 25-year transferable limited warranty on workmanship. It does not cover French drains, dry wells, the sump pit or the pump.
