Manufactured using coextrusion and advanced polymer science, InterAx features an optimised multi-axial geometry that delivers superior confinement, load distribution, and trafficking performance compared to conventional biaxial, triangular aperture geogrids and chemical stabilisation methods.
By increasing the stiffness and compaction of granular layers, InterAx reduces lateral movement, rutting, and differential settlement across a wide range of subgrade conditions. Its ability to perform effectively with a broader range of aggregate types and gradations provides greater design flexibility while enabling aggregate thickness reductions of up to 70%, resulting in faster construction, lower material costs, and reduced carbon emissions of up to 65%.
To support design, specification, and performance validation, InterAx is backed by Tensar+, an industry-leading design platform that simplifies pavement optimisation. Tensar+ enables engineers to rapidly evaluate different design scenarios, assess cost and carbon savings, and generate project-specific design outputs with confidence – backed by decades of performance data and rigorous testing. You can access Tensar + here.
Proven across public roads, heavy-duty pavements, working platforms, railways, and foundation applications, InterAx delivers a resilient, high-performance stabilisation solution designed to withstand heavy loads, repeated trafficking, and severe environmental conditions.
