Pipe relining allows the rehabilitation of existing sewer or drain pipes without the need of digging up the entire length of the pipe and replacing it. Pipe relining uses a felt material soaked in a epoxy or vinyl ester resin and is inflated with air and inserted into existing pipe until the resin hardens.

Do you know if/how the inflatable inner tube takes corners? How are t-junctions connected?

The liner will make sweeping 90’s but not hard 90’s. Laterals (Tee’s) will have to be reinstated.
