Roots at nearly every joint
Many joints means many entry points, which lining closes together.
CIPP Pipe Lining
Clay Pipe Lining in Knoxville, TN
Seal the joints of old vitrified clay sewer pipe so roots and groundwater stop getting in.

- ResultSeamless pipe within a pipe
Vitrified clay pipe is tough, but it was laid in short sections with many joints. Over decades those joints loosen, shift or crack, and roots and groundwater follow. A clay line may look fine from the surface and still be full of roots below. Clay pipe lining gives the old pipe a smooth, jointless interior so the line stops leaking and stops collecting roots, and it is often the best first answer for older Knoxville neighborhoods.
We camera the clay line, cut or jet away roots, and cure a liner sized to the pipe. The liner spans every joint and crack. If the pipe has an offset, sag or break, we show it to you and explain whether lining, a point repair or replacement is wiser. We report what we find honestly, because clay sometimes needs a hybrid solution.
When this is the right call
Groundwater inflow after rain
Clear water seen on camera points to joint leaks.
Cracked or broken sections
Clay can fracture under load or from tree roots.
Repeated rodding
If the line needs clearing every year, the joints are the real issue.

Clay Pipe Lining: answers
Will roots grow through the liner?
Roots need a gap to enter. A continuous liner closes the joints, though roots outside can still press on the pipe.
Can you line clay that is out of round?
Slight deformation is fine. Severe deformation may call for replacement.
Is clay pipe still strong?
Clay resists chemicals well but is brittle. Lining adds a flexible structural layer.
Do I need to replace the whole line?
Often no. Lining is commonly enough, and we explain when it is not.
