mastaGRID® biaxial geogrids, geocomposites, and TerraGrid® flexible high-strength geogrids and geocomposites are widely employed to reinforce and stabilize subgrades and subbases. They are commonly used in the construction of temporary unpaved roads, permanent paved flexible roads, as well as working platforms for plant equipment.

Our quality geogrids and geocomposites provides the following benefits:

  • Distribution of loads and therefore reduction in stress concentration over the soil
  • The geogrid structural junctions, rigid ribs and thick walls help interlock aggregate, increasing its shear resistance
  • When a vertical load is applied, the aggregate is restrained by the ribs, reducing deformation and settlement (known as lateral restraint)
  • Decrease in long term deformation (creep settlement)
  • Reduced granular subbase thickness
  • Controls differential settlement
  • Subgrade stabilisation using high-modulus geosynthetics
  • Asphalt reinforcement and crack control using fibre-glass and other high-modulus geogrids and geocomposites

Key Learnings

  • Applications & features of our geogrids & geocomposites
  • Principles of subgrade stabilisation & reinforcement
  • Flexible pavement design (CBR% / Austroads)
  • Working Platforms (BRE470, UK)
  • Future design research collaboration (SPARC)
