The T-Liner one-piece homogenous main and lateral CIPP connection liner from LMK Technologies is ASTM F2561 compliant. It has a uniform wall thickness and incorporates compressible lining material at the upstream and downstream ends, creating a smooth tapered transition to the host pipe. Both the mainline and lateral sections are formed as a structural cylinder that renews 18 inches and 360 degrees of the mainline, and extends up the lateral pipe as one continuous lining. It combines with Insignia compression gasket-sealing technology to provide a verifiable non-leaking system. These compression gaskets are embedded between the host pipe and the T-Liner, and are compatible with all pipe types including polyethylene. A permanent Lateral Identification Indicia is placed on the main liner that includes the building address and other information regarding the raw materials and other manufacturing details. 815/433-1275; www.lmktechnologies.com.
