Extensive performance research has shown that hexagonal aperture confines aggregate better to support and spread heavy load, limiting rutting and differential settlement, prolonging serviceability.

TriAx geogrid is developed under this principle. It is ideal for formation of temporary access, haul road and working platform. The geogrid can be laid on area with CBR as low as 2. A layer of granular can be spread onto the geogrid to form an immediate stiff formation for construction traffic and load bearing subgrade.
