DuraGrid X:

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 reinforcement 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.

For applications where radial stiffness at very low elongation is required, such as for effective stabilisation in pavements and foundations, DuraGrid X is an ideal choice offering excellent radial properties along with high junction efficiency.

Tenax 3D:
Made from a unique extrusion technique, Tenax 3D triplanar grids are an integrally formed geogrid that is specifically shaped to maximise aggregate interlock and improve the composite stiffness of the aggregate/geogrid mass.

Combining a unique high T shaped rib structure, excellent junction strength and radial stiffness, Tenax 3D geogrids have been proven to provide improved performance in a pavement application, and also excellent composite stiffness performance.

The performance data from full scale testing has been used to produce an excellent pavement design tool which can demonstrate the savings between a stabilised and an un-stabilised pavement section.
