Biaxial Geogrids for Base Stabilization
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.
Uni-Axial Geogrids for Slopes & SRW's
Uniaxial geo grids typically have their tensile strength in the machine (roll) direction. They are mainly used to reinforce the soil mass in a steepened slope or segmental retaining wall. On occasion, they function as a wrapping to confine the aggregate in the wire forms of welded wire faced steepened slopes.
US Fabrics uniaxial geogrids are made from polyester yarn, knitted or woven into a stable structure and have a PVC or polymeric coating. These flexible, user-friendly geogrids are inert to biological degradation and resistant to creep, strain and naturally found chemicals. US Fabrics is pleased to offer Stratagrid geo grid by Strata Systems, Inc. for retaining walls and slopes. Stratagrid is the only precision knitted uniaxial geogrid available in the market today.
Some lighter strength polyester geogrids such as Stratagrid 150 are biaxial. These flexible grids are perfect for retaining walls less than 6' tall and are ideal for the novice retaining wall builder or homeowner.
