Diasen s.r.l




Bentonite geo-composite sheet, self-expanded, characterized by a high swelling capacity, suitable for pre casting waterproofing of structures or underground rooms, such as foundations, garages, elevator pits, fences, foundation slabs, underground parking areas, landfill sites. Suitable for artificial lakes or water basins. The geo-composite is made by a non woven fabric, saturated with bentonite and perfectly sewn to the polypropylene fabric so the bentonite is definitively trapped inside the micro-cells, avoiding any possibility of sliding due to cuts, tears, vertical application or simply moving. Bentonite waterproofing sheet, self-adhesive and self-sealing, to realize geo-composite barriers for pre casting waterproofing of foundations and underground rooms and for the application under ground level.
