Biaxial geogrids are designed to have approximately 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.
Midwest Construction Products offers a wide variety of GeoGrids for base  reinforcement. Depending on if you are looking for polypropylene or polyester we have or can get what you need. 

Midwest Construction Products also carries a full line of high quality uniaxial geogrids.   Uniaxial geogrids are stronger in one direction which is typically the machine direction.   Typical applications using uniaxial geogrids would be:

· Block Retaining walls

· Modular type concrete retaining walls

· Steepened slopes

· Wrap faced walls

· L-unit and Gabion walls
