The Performance Liner® Lateral System is a unique cured in-place process that allows the installer the freedom to position the liner anywhere in the pipe by inverting through a cleanout. The liner can be directed either upstream or downstream using LMK’s patented guide shoe. In addition, this versatile system is capable of being installed in pipes under foundations, inside walls, or in vertical applications. LMK’s Lateral system is truly a no dig situation for renewing lateral pipes since the entire process can be completed through a cleanout. 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.
LMK’s lateral liners also include compressible material at the upstream end of the liner, producing a smooth tapered transition to the old pipe. This process renews laterals from 4 to 8 inches in diameter in continuous lengths up to 130 feet. Inversion tanks come in two sizes (36 inch or 18 inch) and are equipped with a camera port so the liner can be visually inspected under pressure for proper placement prior to the liner being cured.
