How is the (CIPP) Pipe Lining Done?

In the case of fiberglass CIPP lining, the broken pipe is cleaned and a robotic camera is run through the pipe noting any issues that may need to be addressed before the lining is installed. A pre-liner is first pulled into the pipe then the fiberglass liner is pulled inside that.

The liner is then inflated and the UV light curing device is pulled through via a computer which controls the speed, temperature and pressure of the process carefully monitoring all steps.

When the cure is complete, the ends of the liner are trimmed and a cutter is inserted and precision cuts are made at each pipe feeding into the main. A length of 300 feet of 8 inch UV CIPP liner can be cured in 50 minutes – compare that to digging up a whole street.
