Tensar InterAX® Geogrid
Tensar InterAx® Geogrid is a next-generation subgrade stabilisation solution, engineered to improve soil–aggregate interaction and deliver long-term performance across a range of ground conditions.
Manufactured through coextrusion and advanced polymer science, Tensar InterAx® Geogrid features an optimised multi-axial geometry that delivers next-generation performance in confinement, load distribution, and trafficking. It outperforms traditional biaxial geogrids, triangular aperture designs, and chemical stabilisation methods.
By increasing the stiffness and compaction of granular layers, InterAx reduces lateral movement, rutting, and differential settlement across a wide variety of subgrade conditions. Its compatibility with a broader range of aggregate types and gradations increases design flexibility while enabling aggregate layer thickness reductions of up to 70%. This leads to faster construction, lower material usage, and a reduction in carbon emissions of up to 65%.
To support effective design, specification, and validation, InterAx is supported by Tensar+, a powerful geotechnical design platform that simplifies pavement optimisation. Tensar+ allows engineers to quickly compare design alternatives, quantify cost and carbon savings, and produce project-specific design documentation—backed by decades of field data and rigorous performance testing. Access Tensar+ here.
Proven across public roads, heavy-duty pavements, rail infrastructure, working platforms, and foundation applications, InterAx provides a resilient and high-performance stabilisation solution engineered to withstand high loads, frequent traffic, and challenging site conditions.

Frequently Asked Questions
How does InterAx geogrid improve performance compared to traditional biaxial geogrids?
InterAx features a next-generation multi-axial aperture geometry that improves aggregate confinement and interlock. This results in more effective load distribution, increased layer stiffness, and reduced deformation under traffic. The outcome is longer-lasting pavements, reduced maintenance requirements, and improved overall performance compared to conventional biaxial geogrids.
Can using InterAx reduce the amount of aggregate required on site?
Yes. InterAx can reduce aggregate layer thickness by up to 70% while still achieving required performance standards. This leads to lower material costs, fewer truck movements, faster installation, and a significant reduction in environmental impact.
Is InterAx geogrid supported by design tools or certification?
Absolutely. InterAx is BBA certified for subgrade stabilisation and fully supported by the Tensar+ design platform. This allows engineers and contractors to develop efficient, compliant designs with confidence – backed by proven performance data and validated modelling tools.
