How the Perma-Liner System Works...

1. The existing sewer is first inspected with a sewer camera. The camera allows us to identify the level of tree root infiltration, and the overall condition of the existing pipe. We then determine the length of the Perma-Liner "sock" that is will be inserted.
2. The Perma-Liner System liner, which is a PVC coated polyester needle felt tube reinforced with a fiberglass scrim, is cut on site according to the acquired measurements.
3. The resin mixture, a two part 100% epoxy resinspecifically designed for the Perma-Lateral System, is mixed and weighed for insertion into the Perma-Liner Sock.
4. The resin mixture is then poured into the Perma-Liner Sock.
5. The Perma-Liner Sock is then rolled several times to cause complete impregnation of the resin into the PVC sock material.
6. The Perma-Liner Sock is then inserted into the Perma-Liner "Permaverter", which uses air pressure to expand the liner into the pipe.
7. The Permaverter is then attatched to the existing pipe where the sock is then injected with air pressure. A Perma-Liner balloon is then injected into the Perma-Liner Sock by the same process, and is then inflated to a constant pressure. Four hours of setting time are required before the balloon is removed to leave a new Perma-Line pipe as shown below.
