Tenax® 3D Geogrid

Tenax 3D geogrids add a whole new dimension to geosynthetic stabilisation and reinforcement.

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. Contact us for more information.

Frequently Asked Questions

We have full scale pavement testing and also a composite stiffness test comparison with other common geogrids.

The 3D triplaner grids have been in production for some time in Europe and USA however the unique new technology has only just completed the required rigorous testing programs to give us confidence to launch into the Australian market. This is the very latest geogrid technology from one of the world’s leading and trusted manufacturers.

The pavement testing which has been completed by the world renown TRI facility has been used to produce a pavement design tool based on AASHTO methodology. This can give a comparison between stabilised and unstabilised sections.

Although both DuraGrid X and Tenax 3D share some physical properties, the Tenax 3D is a significant improvement for road pavement applications thanks to a specialised “T” beam profile, providing a much higher transversal lateral confinement and a better distribution of the load on soft subgrades.

The Tenax 3D-HT is slightly stronger than the Tenax 3D-T, providing a higher initial modulus and radial stiffness at low strain. We recommend Tenax 3D-HT for CBR values less than or equal to 2% and Tenax 3D-T for CBR values above 2%.

Tenax 3D maximises interlocking within the aggregate-grid composite, provides higher transversal lateral confinement and has excellent aperture stability.
