Tensar TriAx TX

Using over 30 years’ experience in subgrade stabilisation, Tensar has radically re-engineered the fundamental structure of geogrids to create the revolutionary TriAx, based on one of the most efficient and stable structural forms –  triangles.

Whereas the tensile stiffness of biaxial geogrids is predominantly in two directions, TriAx® is multi-directional. The product has near isotropic tensile properties, through 360°.The aggregate particles interlock within the triangular apertures and the efficient, deep rib profile of TriAx geogrid helps to confine aggregate. Combined with the isotropic stiffness this creates a mechanically stabilised layer with exceptional performance.

Many tests and trials have been conducted to assess the performance of Tensar TriAx geogrid in mechanically stabilised layers subject to repeated wheel loadings, in particular at the University of Nottingham and the Transport Research Laboratory (TRL). It has been shown that TriAx outperforms even Tensar biaxial geogrids. Load bearing trials at the Building Research Establishment (BRE) also showed outstanding results in distributing static loading, a common situation in many projects such as working platforms for cranes and for tracked machinery such as piling rigs. 
Tensar’s TriAx geogrid technology also comes with extraordinary technical support from our team of experienced Engineers. Using our unique TensarPave software, we can offer you everything from a straightforward application suggestion up to a full Design and Supply service to help you to get the best from TriAx in your project.

    Simply input your parameters and find out how TriAx can add value to your project by reducing pavement thickness and maximising cost benefits.

    When compared with an unreinforced aggregate layer, a mechanically stabilised layer incorporating TriAx geogrids can:

    • Increase the bearing capacity 
    • Control differential settlement 
    • Extensive local stocks readily available 
    • Cut construction CO2 emissions by up to 50% 
    • Reduce the excavation needed 
    • Full design service from concept to finalised design
