Extensive performance research has shown that hexagonal apertures confine aggregate better to support and spread heavy loads, limit rutting and differential settlement, and prolong serviceability.

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