<p>The liner has a composite pack-like structure with an intermediate support (11) made of geocompatible textile material having a high degree of mechanical strength, and two layers (12-13) of water-expandable material. Each layer of water-expandable material is delimited by further surface containment layers (14-15) which are also made of highly permeable geocompatible textile material. <IMAGE></p> |
