UV-cured CIPP uses a glass-fiber liner and a train of ultraviolet lamps that travels through the pipe, hardening the resin as it goes. Because the cure is driven by light rather than heat, the process is quick, well controlled and easy to monitor. It is a strong choice for sewer mains, storm lines, culverts and commercial pipes where time and consistency matter, and it is increasingly used for residential work in the Knoxville area.
We prepare the pipe, pull in the liner, inflate it with air and send the light train through at a speed set for the liner and diameter. Sensors track temperature and pressure so the cure is recorded start to finish. After the cure we open side connections, run the camera and give you the video and a cure record. As with every CIPP method, we start with a Free Estimate and recommend the cure that fits your pipe, not the one that is simplest for us.

UV-Cured CIPP Lining: answers
Is UV curing better than heat?
Each has strengths. UV is fast and precise, and heat or steam can suit smaller residential lines. We recommend what fits.
Does UV work in wet pipes?
The pipe is bypassed or dried so the liner can be installed and cured properly.
Can UV lining handle bends?
Within limits, yes. The camera and diameter tell us whether a UV liner will follow the path.
Is it safe for the environment?
Cured liners are inert, and UV curing avoids releasing steam and hot water to the system.
