<p>A composite (1) for geotechnics, building and the like, with an impermeable layer, comprising a sheet-like element (2) that is impermeable to fluids and has, monolithically therewith, elements (10, 12) that protrude on the first and second faces, on at least one of the faces there being a layer (5) that is integrally coupled to the protruding elements to form, at the first and/or second faces, two separate drainage and/or protection and/or grip systems adapted to withstand intense compression along a direction that is substantially perpendicular to the sheet-like element.</p> |
