Tensar Geogrid Products — TriAx & TX Series

Geogrids separate, reinforce, protect, and stabilize soil layers while increasing load-bearing capacity. They allow engineers to reduce aggregate or subbase thickness, lower construction costs, and improve the long-term performance of paved and unpaved roadways, retaining walls, slopes, and soft ground conditions — making them essential in civil infrastructure and geotechnical applications.

For pavement applications, Tensar TriAx Series geogrids feature a triangular aperture pattern that distributes load radially in multiple directions, providing superior stabilization for pavement base layers over soft subgrades. By mechanically stabilizing aggregate layers and spreading applied loads over a larger area, they allow for significant reductions in required aggregate or subbase thickness, directly lowering material and hauling costs while extending pavement service life.

Biaxial geogrids reinforce soil in two directions — longitudinal and transverse — making them ideal for retaining walls and steep slopes. Triaxial geogrids, like Tensar's TriAx Series, feature a triangular aperture pattern that distributes load radially in multiple directions, providing superior stabilization for unpaved roads, parking lots, and pavement base layers over soft subgrades.

Tensar geogrids are engineered for permanent, long-term performance. Made from polypropylene, they are resistant to UV radiation, soil chemicals, and mechanical damage. When properly installed, Tensar TriAx and TX Series geogrids are designed to last the full design life of the structure they support — commonly 75 to 100 years for permanent civil infrastructure projects.

Tensar TriAx and TX Series geogrids are used in a wide range of civil applications including paved and unpaved roadway construction, Geosynthetic-Reinforced Soil (GRS) walls and slopes, retaining walls, parking lot construction, railroad and airport infrastructure, bridge abutments, mining and logging access roads, wind farm site access, and landfill construction.

Yes. Tensar geogrid products supplied by Coleman Moore Company meet DOT compliant specifications and satisfy project performance requirements for civil and environmental applications. Coleman Moore works with Iowa DOT contractors, engineers, and municipalities to ensure product selections align with applicable regulatory and project-specific standards.

Coleman Moore provides on-site Dynamic Cone Penetrometer (DCP) testing with CBR conversion and integrates Tensar Plus design software to optimize pavement thickness and reduce aggregate usage on every project. They also offer comprehensive cost-benefit analysis and strategic site evaluations to help reduce material costs, prevent project delays, and extend the service life of your infrastructure.
