InterAx Geogrid — Advanced Geosynthetic Stabilization

Tensar InterAx geogrids typically require a minimum overlap of 12 to 18 inches at panel joints, though project-specific specifications may call for greater overlap in soft or highly variable subgrade conditions. Always follow the project engineer's design specifications and Tensar's published installation guidelines to ensure proper interlock and load transfer performance.

Tensar geogrid installation involves preparing and grading the subgrade, unrolling the geogrid panels in the direction of construction traffic, overlapping joints per specification, and securing edges if required. Aggregate is then spread and compacted over the grid. Coleman Moore provides full installation consultation and site evaluation support to ensure correct placement and performance.

InterAx Geogrid is used for roadway and pavement reinforcement, unpaved access roads for mining, logging, and wind farms, parking lot construction over soft subgrades, retaining walls, GRS slopes, railroad and airport base stabilization, bridge abutments, and landfill access roads. Its multiaxial design makes it ideal wherever subgrade stabilization and load distribution are critical.

Yes. Tensar InterAx Geogrids meet DOT-compliant specifications and satisfy project performance requirements for civil and environmental applications. Coleman Moore Company works closely with engineers, municipalities, and Departments of Transportation across Iowa to ensure all products meet applicable regulatory and design standards for public infrastructure projects.

InterAx Geogrids are manufactured from polypropylene, available in biaxial and triaxial configurations. The material is resistant to UV radiation, chemicals found in soil, and mechanical damage during installation and service. This makes it suitable for permanent, long-term applications in demanding civil and geotechnical environments without performance degradation over time.

By mechanically stabilizing aggregate and improving subgrade load capacity, geogrids allow engineers to reduce the required thickness of aggregate or subbase layers. This directly lowers material and hauling costs, shortens construction timelines, and reduces long-term maintenance expenses. Coleman Moore's cost-benefit analysis service helps quantify these savings for each specific project site.
