Perma-liner is a trenchless method of repairing broken or damaged sewer pipes. It involves inserting a flexible liner, usually made of felt or fiberglass, into the damaged pipe through an access point. Once the liner is in place, it is inflated using compressed air or water pressure, causing it to conform to the shape of the damaged pipe.

Next, an ultraviolet (UV) light ray is inserted into the liner and moved along the length of the pipe, curing the resin in the liner and causing it to harden. The resulting hardened liner essentially creates a new pipe within the existing damaged one. This process typically takes several hours to complete, but can vary depending on the size and extent of the damaged area.

One of the main advantages of Perma-liner is that it is a non-invasive method of repair that does not require digging or excavation, which can be both costly and disruptive. It also provides a more durable and longer-lasting solution than traditional pipe repair methods. The liner is resistant to corrosion and is designed to withstand the harsh conditions inside sewer pipes.

Overall, Perma-liner is a highly effective and cost-efficient solution for repairing damaged sewer pipes. It provides a long-lasting, durable solution that is less disruptive and invasive than traditional repair methods.
