What is Trenchless Pipe Lining?

The majority of sewer malfunctions can be fixed by installing a pipe within a pipe in a process called trenchless pipe lining. A tube filled with epoxy resin is inserted into the pipe that needs to be repaired. The resin is inflated to coat the inner walls of the pipe before it is steam blown for a couple of hours, allowing it to cure and harden into the new pipe.
burst the old pipe with a machine that pulls the new pipe behind it, allowing the new pipe to take the place of the old one as it is fractured apart.
