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 an epoxy or vinyl ester resin and is inflated with air and inserted into the existing pipe until the resin hardens.
