Sustained flow capacity and sand tightness are achieved at all strains. In very exposed areas where it is possible that accretion of sands may not occur, a secondary mineral filter layer is placed prior to the primary rock armour. Design charts are available that point to the most appropriate GEOfabrics' product once the size of rock has been established. The savings in transport, plant and materials is considerable compared with the alternative of having to design/install multiple, graded, mineral filter layers GEO fabric filter/separator non woven geotextile
