LMK’s Performance Liner® Sectional process renews pipes from 6 to 36 inches in diameter and in continuous lengths up to 50 feet. The liner can be inverted anywhere in the pipe with no trimming or cutting. The result is a structural, root proof, water-tight seal. Performance Liner Sectional conforms 100% to ASTM F2599-11. Gasket sealing technology is used at the terminating points of the liner by embedding LMK patented Insignia™ Hydrophilic O-Rings between the liner and host pipe to ensure a water-tight seal.
Compressible material is incorporated at the upstream and downstream ends of the liner for a smooth tapered transition to the old host pipe. During the positioning process there is no resin loss, because the liner is fully contained in the launch hose. Resin comes in contact with the pipe only at the point of repair and migrates into fractures and open joints creating a mechanical lock. Unlike other less precise systems, air pressure is never dropped, which would allow jarred sections of pipe to collapse onto the liner causing further damage and a potential dig. Other 2-step inversion systems also have an uneven resin distribution from the crown to the invert of the pipe. Performance Liner Sectional Repairs are a one-step, long-term, CIPP solution.
