A drain at the wall, a pump at the end.
A perimeter drain inside the basement collects water where the floor meets the wall and sends it to a sump pump, relieving pressure under the slab.
- Timeline: One to three days
- Parts: Drain pipe, gravel, sump, wall liner
- Mess: Contained, with dust control
What it is, and why it matters.
Water pressure builds under a basement slab. The weakest point is the joint where the floor meets the wall, and water comes up there first. An interior drain channel catches it and carries it to the sump.
We cut a small trench, lay a perforated pipe in clean gravel, tie it to a sump basin and patch the floor, with a wall-base system to guide moisture from the block into the drain.
Four things done right.
Targets the entry point
The floor-wall joint is where water enters.
Relieves pressure
Water is pulled from below the slab.
Contained work
Dust is controlled and floors are patched.
Long-lasting
Pipe and gravel are built to stay open.

Interior Drain Systems: common questions
Will the drain clog?
Properly installed drains with clean gravel and filter fabric can last many years, and the sump can be flushed and checked in an annual service.
Does it replace exterior waterproofing?
It works from inside and is often the more affordable, less disruptive choice. Exterior waterproofing keeps water from reaching the wall at all and fits some projects.
