Geogrids are used in both soil reinforcement and stabilisation functions. Soil reinforcement geogrids are generally used in long term loading applications and rely predominantly on long-term tensile strength which includes factors catering for tensile creep. These strength-based geogrid applications include reinforced soil walls & slopes, void spanning, basal embankment reinforcement, load transfer platforms, and veneer stability. Most geogrids used in these applications will be uniaxial (predominant tensile strength in one direction) but biaxial geogrids (similar tensile strengths in two orthogonal directions) are also utilised Soil stabilisation geogrids are used in transient loading applications and rely mostly on tensile stiffness, geogrid-soil interlock, and the resulting soil confinement and lateral restraint. These confinement-based stabilisation applications include subgrade stabilisation, pavement optimisation, and soft soil capping. Geogrids used in these applications will be biaxial geogrids with similar stiffness in two orthogonal directions or multiaxial geogrids, like TriAx® or InterAx®.
