What Is Geogrid?
Geogrid is a polymer mesh designed to mechanically stabilize aggregate bases. When placed between the subgrade and base course, it interlocks with stone to distribute loads across a wider area and limit lateral movement. This can reduce rutting, prevent base contamination from soft soils, and help extend pavement life.
Tensar manufactures several Geogrid product lines, each engineered for different applications:
- InterAx® (NX Series): Multi-axial Geogrids with hexagonal apertures that provide 360-degree stability. Ideal for unpaved roads, parking lots, and sites with variable traffic patterns.
- TriAx® (TX Series): Triangular aperture Geogrids offering multi-directional strength. Well-suited for paved roads, highways, and heavy-duty applications.
- Biaxial (BX Series): Rectangular aperture Geogrids designed for bi-directional loading. Commonly used in retaining walls, slopes, and foundation reinforcement.
How Geogrid Works
When aggregate is compacted over Geogrid, the stone particles partially penetrate the apertures and lock into place. This creates a mechanically stabilized layer that resists movement under load. As traffic passes over the surface, forces are distributed laterally through the Geogrid rather than concentrating on weak spots in the subgrade.
The result is a stiffer base that can support heavier loads with less material. In many cases, Geogrid allows engineers to reduce aggregate thickness while achieving equivalent or better performance—saving on excavation, hauling, and material costs.
The Evolution of Geogrid Technology
Tensar invented the Geogrid in 1978 and has continued advancing the technology ever since. Their Biaxial (BX) series, introduced in the 1980s, featured rectangular apertures for bi-directional reinforcement—ideal for retaining walls and foundation support. In 2007, Tensar launched the TriAx® series with triangular apertures that provide radial stiffness in all directions, improving performance under multi-directional traffic loads. The latest innovation is the InterAx® series (2021), which uses hexagonal geometry with multiple aperture sizes and coextruded outer layers that conform to aggregate particles for enhanced interlock. Each generation builds on decades of research and field-proven performance.
Choosing the Right Geogrid
The best Geogrid for your project depends on your soil conditions, expected traffic, and structural requirements. Soft or saturated subgrades often benefit from higher-grade products like NX850 or TX190, while stable soils may only need lighter reinforcement. Pavement type also matters—unpaved surfaces see different stress patterns than asphalt roads.
