Tensar InterAx Geogrids
A geosynthetic is a synthetic product, usually made from or including polymeric materials, that are used to solve civil and geotechnical engineering problems in or on the ground. Geosynthetics add to or enhance the functions of conventional materials to make construction more efficient, cost-effective, and reliable. Designs using geosynthetics should be based on the function(s) of the selected materials to meet the engineering objective(s). Geogrids were invented by Tensar in the late 1970s and are a category of geosynthetic material that can be used to provide the functions of reinforcement, stabilization, and filtration.
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.
Tensar's InterAx geogrid is fully compatible with their 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.
Highlights
-
- Proven Success - Tensar's InterAx geogrid has already been installed on countless projects across the globe, proving its value to many satisfied customers
- Proven Savings - InterAx geogrid was specifically designed to provide greater overall cost savings through thinner aggregate layers and more fill options
- Proven Technology - Twelve global teams and over 10,000 hours of research and development have led to the development of Tensar’s InterAx geogrid, their highest-performing geogrid to date. Optimized geometry gives maximum confinement of granular fill, creating the most efficient stabilized layer. Advanced material science improves compaction and restricts movement over time, retaining the stiffness long term and further enhancing performance. InterAx has been tested at the world-class US Army Corps of Engineers’ Engineer Research and Development Center (ERDC) in Vicksburg, Mississippi
- Interactive Layer - InterAx geogrid exhibits “crush-fit” outer layers, where the geogrid ribs conform to the shape of the aggregate and better hold it in place. InterAx geogrid is designed to exhibit both elastic (rebound) and plastic (permanent) response to facilitate this “crush-fit” interaction
- Compliance to Improve Compaction - InterAx geogrid has repeating, open hexagonal element that better accommodates aggregate entry and facilitates compliance during compaction. The improved nesting of the aggregate within the geogrid created by the floating hexagon leads to faster and better quality compaction
- A Broader Range of Aggregate - As a result of its greater range and distribution of aperture shapes and sizes, Tensar’s InterAx geogrid is designed to work well with a broad range of aggregates and granular materials. This gives you more flexibility in choosing the aggregate for your project, leading to greater cost savings and more sustainable solutions
- Improve Lateral Restraint - Tensar’s InterAx geogrid demonstrates a 40% higher aspect ratio on all ribs compared to conventional grids. This provides improved lateral restraint of the aggregate, resulting in enhanced stiffness of the section
- 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
