The product overview for TriAx, the triangular geogrid Tensar developed to replace the older biaxial grids for trafficked surfaces, and what the change in geometry was meant to achieve.
Useful background rather than a working document. The point of the triangular geometry is that a biaxial grid is stiff in two directions and a triangular one is stiff in every direction in the plane. Load under a wheel does not travel along the roll, so a grid that only resists in two axes is leaving capacity on the table.
Worth knowing when reading older specs: TriAx superseded the BX biaxial grids for trafficked surfaces, and has itself largely been superseded by InterAx and the H-Series. A spec written a decade ago may call for a TX number that is no longer the current product, and that is a renaming rather than a discontinuation in most cases.
Our cross-reference tool matches the old TX numbers to what is available now, including the TriAx TX130s, TX140 and TX160 designations that still appear on plan sets.
Road Fabrics stocks the Tensar range. The installation guide is the field document, and the roll calculator will work out quantities.
