TerraGrid® Uniaxial Geogrids

TerraGrid® uniaxial geogrids are designed for use in retaining walls, steepened slopes, embankments constructed over weak subgrades, and temporary shoring.

TerraGrid® uniaxial geogrids are made up of high tenacity polyester yarns with a polymer coating. They are non-biodegradable and resistant to most soil chemicals, acids, and alkalis with a pH range of 4 to 9. TerraGrid® geogrids are manufactured to meet or exceed the following physical properties:
