Geogrids
| Bi-Axial Geogrids for Base Reinforcement |

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 and rolling together two layers of extruded, polypropylene, flexible geogrids to create a continuous sheet that will not seperate. The two grids are offset before welding, creating a stable, continuous sheet with random sized aperatures for improved soil interaction.
| Uniaxial Geogrids for Retaining Walls and Slopes |

Uniaxial geogrids 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 geogrid 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.
