STF 3D XL

Polypropylene 3D Geogrid

‍

STF 3D XL geogrid is manufactured from a unique extrusion technique resulting in a perforated polypropylene sheet that is specifically shaped in three directions (3D). This unique extrusion technique produces a particularly large concaved shaped rib thereby trapping stone particles within the large aperture and enhancing the interaction mechanism between geogrids and granular soils by restricting the horizontal movement of soil particles and preventing further displacements. This increase in interaction from the 3D XL geogrids enables consistent reductions in aggregate layer thickness.
