CIPP Pipe Lining
Under-Slab Pipe Lining in Knoxville, TN
Repair drains and sewer lines beneath a concrete slab without breaking the floor.
- DiggingAccess points only
- MethodCured in place
- ResultSeamless pipe within a pipe
Many homes and businesses have sewer and drain pipes buried below the foundation slab. When they fail, a traditional repair means jackhammering floors, tunneling or relocating plumbing. That is messy, loud and expensive, and it can disturb flooring and finishes. Under-slab pipe lining repairs the pipe from the cleanout, preserving the slab and the floor above.
We camera the line beneath the slab, locate the defects, and use lining or point repair to restore it. We can often reach the pipe through existing cleanouts or fixture openings. We explain whether lining, a point repair or a trenchless replacement under the slab will work best, and we explain limits when the pipe is collapsed or badly offset.
When this is the right call
Persistent sewer odor
Odors inside the home may come from a broken drain beneath the slab.
Repeated backups with no outside cause

A liner is a structural repair in many cases, and we explain when replacement is advised.
