A tubular liner for use in softlining methods of pipe rehabilitation. The tubular liner is constructed of plastic materials or laminates of plastic material which have one or more resin-absorbing layers. The tubular liner of the present invention is made by stitching together the faces of the liner material to form a tube. The seam of the tube is then sealed and the sealed seam is fused to the tube. The resulting structure provides a durable tubular liner that resists rupture or leakage of the seam during use in pipe rehabilitation operations.

Tubular liner for softlining pipe rehabilitation

The present invention provides a novel method for softlining rehabilitation of pipe conduits in which the lining hose comprises an inner layer of resin-absorbing material and an outer layer which is a disintegrable coating. The outer layer initially allows for soaking the resin-absorbing material with resin, but disintegrates during installation so that the resin can contact the interior surface of the pipe conduit and provide an improved rehabilitation method. The present invention further provides a novel lining hose for use in softlining rehabilitation.
