Load distribution is 3-dimensional in nature and acts radially at all levels in the aggregate. For a stabilised layer to be effective it must have the ability to distribute load through 360 degrees. To ensure optimum performance, the geogrid reinforcement in a mechanically stabilised layer should have a high radial stiffness throughout the full 360 degrees.

Multi-directional properties

Biaxial geogrids have tensile stiffness predominantly in two directions.

TriAx geogrids have three principal directions of stiffness, further enhanced by their rigid triangular geometry.

TriAx has a significantly different structure to any other geogrid, which provides high strength and stiffness around 360 degrees.

A truly multi-directional product with near isotropic properties.
