Performance Liner® Lateral Lining

The LMK lateral lining system is a unique cured in place process that allows the installer the freedom to position the liner anywhere in the pipe by inverting it through a cleanout. The liner can be directed either upstream or downstream using LMK’s patented guide shoe. LMK’s Lateral System is truly a no-dig solution for renewing lateral pipes, since the entire process can be completed through an inside or outside cleanout or manhole. Gasket sealing O-rings are placed at the upstream and downstream ends of the liner, providing a verifiable, non-leaking lateral liner that is compatible with all types of piping. This process renews laterals from four to eight inches in diameter in continuous lengths up to 130 feet.


LMK Technologies has pioneered CIPP lateral renewal technology and has driven the industry forward with new products and technologies to facilitate sewer rehabilitation of sewers for 20 years. In its relatively small lifespan as a company, LMK has invested time and resources in research and development
