Tensar InterAx™ Geogrids

10,000+ Hours of R&D
12 Product Teams
  • Most advanced geosynthetic made for trafficked surfaces and foundations
  • Ideal for subgrade stabilization, pavements, and working platforms
  • Optimized geometry for maximum confinement of granular fill, creating the most efficient stabilized layer
  • Advanced material science to improve compaction and restrict movement over time, retaining the stiffness long term and further enhancing performance


There is an increasing demand to build infrastructure more economically, faster, and with more sustainable methods and materials. Over the course of Tensar's 50+ year history, we have invested millions of dollars in research to provide sitework solutions that meet these needs for our customers.

InterAx geogrid combines coextrusion and advanced material science with an optimized geometry to dramatically improve soil interaction and trafficking performance. It provides greater value vs. TriAx® geogrid and other available technologies. InterAx geogrid also drives superior performance across a broader range and quality of aggregate types and gradations, giving you more flexibility in your aggregate choice.


InterAx geogrid is currently available in two SKUs: NX750 and NX850.

Proven Success

Successful clients and construction excellence have been Tensar's mission for over 50 years. Tensar's InterAx geogrid has already been installed on countless projects across the globe, proving its value to many satisfied customers.

Proven Savings

We help you deliver projects more efficiently, no matter what challenges you're facing, just as we have for thousands of loyal customers. Tensar's InterAx geogrid was specifically designed to provide greater overall cost savings through thinner aggregate layers and more fill options.

Compatible with Tensar+ & Enhanced Design Methods

Tensar's InterAx geogrid is fully compatible with our easy-to-use, award-winning design software, Tensar+. Tensar+ saves you time and effort, while ensuring your designs are reliable and deliver the expected results.

Stabilizing a subgrade, passing a proofroll, or designing an unpaved road is easier than ever. Using the enhanced subgrade stabilization method only available in Tensar+, you can design for a broader range of traffic and performance, to better reflect the actual jobsite conditions. This results in a solution that you can count on working the first time.

Trenching with Geogrid

Tensar geogrids are routinely excavated through and punched through in order to place guardrail posts, bridge piers, and underground utilities. The geogrid locks the aggregate and pavement in place, and it isn't disturbed by the adjacent trench.

A Resilient Solution

Tensar geogrids are 100% UV resistant and will not rust, leach, or degrade in direct sunlight. When you build with geogrids, you can count on a higher-performing and longer-lasting solution for future generations to enjoy. Tensar's InterAx geogrid is also a proven component of protecting our infrastructure by planning for and mitigating the effects of unforeseen events, accelerating recovery. InterAx geogrid protects against loss of load-carrying capacity due to storm and flood conditions and mitigates the damaging effects of expansive soils and freeze-thaw cycling. InterAx geogrid significantly reduces restoration times after a shock event, minimizing disruption to residents, businesses, and motorists.
