Tensar® TriAx® (TX) Geogrids

Advanced Geogrids specifically designed for trafficked surfaces.

TriAx Geogrid’s multi-directional properties leverage triangular geometry, one of construction’s most stable and widely utilized shapes, to provide an enhanced level of in-plane stiffness.

Its triangular structure, coupled with improved rib and junction geometry, offers the construction industry an improved alternative to conventional materials and practices.


TriAx Geogrid is manufactured from a punched polypropylene sheet oriented in multiple, equilateral directions to form its triangular apertures, resulting in high radial stiffness throughout the full 360 degrees. This feature yields a more efficient product that delivers optimal in-service stress transfer from the aggregate to the stabilizing geogrid.

TriAx® Geogrid and the use thereof are protected by U.S. Patent No. 7,001,112.
