The first step is to inspect the sewer using a video camera to determine the location and extent of the damage. The inspection assesses the length of the pipe and whether the sewer meets the minimum requirements for a sewer pipe lining.

After the inspection, thoroughly clean the pipe using a high pressure water jetter to get rid of roots and sludge. Use special tools to get rid of fat, oil, grease, dirt, mud and debris. Take a special fabric tube and cut it to the length of the tube you wish to replace. Mix self hardening part A and part B epoxy resins and use them to saturate the fabric tube completely.

Pull the fabric tube into the damaged sewer pipe. You may also use air pressure to blow the liner into the pipe. Inflate the fabric tube with air and leave the tube for two to four hours to harden. After the new sewer pipe lining hardens, use a video camera to inspect the new lining for quality control purposes.

You can install new sewer pipe lining on both vertical and horizontal pipes. You can also install this lining on asbestos pipes or inside architectural pipes without disturbing the asbestos or destroying the stone.
