ABSTRACT:
A geocomposite liner having a first fibrous layer, a second fibrous layer, and a non-fibrous layer secured between the first and second fibrous layers. A plurality of fibers extend from the non-fibrous layer such that the ends of the fibers extend outwardly of an outer surface of the first fibrous layer. The ends are heat fused so as to secure the ends outwardly of the outer surface of the first fibrous layer. The second fibrous layer is needle punched such that the fibers extend from the second fibrous layer through the non-fibrous layer. The ends of the fibers are heat fused such that the ends have a greater diameter exterior of the first fibrous layer than interior of the first fibrous layer. Some of the ends are heat fused together on the outer surface of the first fibrous layer.
