Tensar’s range of geogrids provides proven practical solutions for poor ground conditions combining major cost savings with considerable performance benefits in granular capping and sub-base layers. Tensar geogrids offer considerable savings in granular thickness and reduction of excavated soil together with conservation of natural aggregates. Our expansive Tensar portfolio also offers products for earth retaining walls and slopes, subgrade stabilisation, foundations, reinforcement of asphalt, and pavement optimisation.
Using over 30 years’ of experience in subgrade stabilisation, Tensar has radically re-engineered the fundamental structure of geogrids to create the revolutionary TriAx. Where 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.
