Tensar TriAx® (TX) Geogrids

360° Uniform Radial Stiffness
2M+ ESALs of Performance Validation Testing
500M+ Sq Yds Installed Globally
  • Ideal for subgrade stabilization and optimizing pavement designs
  • Diagonal ribs that increase the in-plane stiffness
  • Triangular pattern forms a hexagon to improve how the product absorbs the forces from traffic loading
  • High aspect ratio provides better interlock with the surrounding aggregate
  • Results in a more resilient solution that will withstand severe weather events, the increasing impact of climate change, and other challenging environmental conditions



Tensar TriAx® geogrid products have helped contractors and pavement engineers around the world stabilize soft soils and optimize pavement designs to get longer service life for their budget. Its multi-directional properties leverage triangular geometry, one of construction's most stable shapes, to provide greater stability and stiffness. Its ability to efficiently confine aggregate reduces installation costs while improving the overall performance of the structure.

Advantages of TriAx Geogrid

This innovative technology has allowed owners, engineers, and contractors to realize the primary benefits associated with triaxial geogrid in both paved and unpaved applications. These TriAx products can optimize the thickness of pavement components, extend the service life of pavement, and provide efficient stabilization of soft ground conditions.

Superior Performance for Paved and Unpaved Surfaces

TriAx geogrid's near-isotropic stiffness characteristics contribute to its improved performance in comparison to Tensar's biaxial (BX) geogrids and geotextiles in trafficked applications. Such characteristics are ideal for improving the service life of paved and unpaved surfaces while further reducing excavation and pavement component thickness requirements.

Cost-Effective Soil Stabilization

Conventional approaches to stabilizing soft soils include removing and replacing (over-excavating) the bad material, placing a thick layer of granular material as a bridge layer, or chemically treating the soil to improve its strength. TriAx geogrids provide a simpler, more cost-effective solution using the functions of filtration and stabilization.

All Geosynthetics Are Not Created Equal.

Your reputation is at stake anytime your stamp is used on a design. At Tensar, we don’t take this lightly. That’s why we have invested extensively in research and testing of our TriAx geogrid, proving its triaxial design and performance parameters time and again. You can use your stamp with confidence every time TriAx geogrid is specified in a design. Don’t risk using products with unproven technologies.

Trenching with TriAx Products

Tensar geogrids are routinely excavated through and punched through in order to place guardrail posts, bridge piers, and underground utilities.

A Resilient Solution

Tensar geogrids are 100% UV resistant and will not rust, leach, or degrade in direct sunlight. No matter your geogrid application, when you build with our products, you can count on a higher-performing and longer-lasting solution for future generations to enjoy.
