Lateral pipe lining is the term used to cover a wide variety of trenchless repairs and replacement techniques using internal linings to repair underground pipes. Lateral pipe lining is one method of trenchless repair which allows for repairs to be completed quickly and in a more cost effective manner rather than digging up leaking pipes to replace them.
Cured in place repairs utilize a plastic-epoxy lining which is applied to the internal wall of the pipe and pressed into place using pressurised air bladders. The result is a new, smooth internal pipe wall with no leaks. Pipes can be accessed through existing entry points or by drilling into the side wall of the pipe at predetermined locations in order to execute the repair. Once the lining is in place, some lateral holes will need to be cut at points where the piping branches and there are inlet or outlet connections to the main line.
