DuraGrid X Geogrid

DuraGrid X 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 X 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 X ensure its usefulness in reducing layer thicknesses and increasing bearing capacity and pavement life.

DuraGrid X 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 X stabilisation layer.

In applications where the underlying soils are saturated, it is recommended that a DuraForce® nonwoven geotextile is placed under the DuraGrid X or the GridTex geocomposite is used. This is to ensure there is separation to prevent the fine particles migrating into the aggregate layer.


Frequently Asked Questions

DuraGrid X is an extruded, punched and drawn polypropylene geogrid.

DuraGrid X is most commonly used for pavement stabilisation over soft soils and the reinforcement of aggregate in raft foundations. DuraGrid X can also be used as a non-slip grid on boardwalks.

In pavement and raft applications, the DuraGrid X’s excellent junction efficiency and a high rib profile provide aggregate interlock and lateral restraint at a very low strain. The support mechanism is, therefore, stabilisation and reinforcement.

StrataGrid is a polyester (PET) geogrid designed for soil reinforced walls, slopes and embankments which are subject to long-term creep.

DuraGrid X is a polypropylene (PP) geogrid designed for mechanically stabilising pavements which are typically exposed to repetitive, short-term loading.
