ABSTRACT:
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.
