DuraGrid - Polypropylene Biaxial Geogrid

DuraGrid polypropylene biaxial geogrids are used in base course reinforcement and subgrade stabilisation applications such as road pavements, reinforced foundations and working platforms on soft soils.

DuraGrid polypropylene geogrids are well suited to applications that are subject to the impact loads caused by traffic, earthquakes, etc. The excellent interlocking properties and strength of DuraGrid ensure its usefulness in reducing layer thicknesses and increasing bearing capacity and pavement life.

DuraGrid is typically laid directly on the subgrade, and the aggregate layers are placed and compacted on top. Aggregates, which are strong in compression and weak in tension, are therefore mechanically stabilised by the high-efficiency interlock and tensile strength of the DuraGrid reinforcement layer. In applications where the underlying soils are saturated, it is recommended that a DuraForce nonwoven geotextile is placed under the DuraGrid or the GridTex geocomposite is used. This is to ensure there is separation to prevent the fine particles migrating into the aggregate layer.

For applications where radial strength or very low elongation is required, see our range of SecuGrid® geogrids. We also offer CombiGrid® which is a composite product of a SecuGrid, combining a nonwoven geotextile, firmly welded between the reinforcement bars.
