Sectional Connection Liner
WRT's Sectional Connection Liner Process renews pipes from 8-12 inches in diameter and in continuous lengths up to 6 ft. while simultaneously renewing the connection and the lateral service pipe for up to 8 ft. The liner can be inverted anywhere in the pipe with no trimming or cutting. The result is a structural, root proof, water-tight liner. Gasket sealing technology is used at the terminating points of the liner by embedding LMK patented Insignia™ Hydrophilic O-Rings between the liner and the host pipe to ensure a water-tight seal.
Compressible material is incorporated at the upstream and downstream ends of the mainline 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 launching device. Resin comes in contact with the pipe only at the point of repair and migrates into fractures and open joints creating a mechanical lock.
