Tensar TriAx TX

Proven to outperform even Tensar biaxial geogrids.
Using over 30 years’ experience in ground 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, but with TriAx® it is now 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 helps to confine aggregate, which combined with the isotropic stiffness, creates a mechanically stabilised layer with exceptional performance. For an animated demonstration of how TriAx works, click here.

Numerous tests and trials have been conducted to assess the performance of TriAx in mechanically stabilised layers subject to repeated wheel loadings, in particular at the Transport Research Laboratory (TRL) and University of Nottingham. 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 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.

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

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