Biaxial geogrids are designed to have roughly the same tensile strength in both directions and to distribute loads over a wider area, increasing the load capacity of the soil. Base reinforcing geogrids interlock with the aggregate to confine the base and reinforce the subgrade. In paved or unpaved applications, they reduce rutting and help maintain the desired aggregate depth.
US Fabrics offers BaseGrid biaxial geogrids for base reinforcement. They are manufactured by welding or stitching together two layers of extruded, polypropylene, flexible geogrids to create a continuous sheet that will not separate. The two grids are offset before welding or stitching, creating a stable, continuous sheet with random-sized apertures for improved soil interaction.
