Geogrid Soil Reinforcement Products

Geogrids are designed for permanent, long-term service life—typically 75 to 100 years or more under normal civil engineering conditions. Made from polypropylene or HDPE, they are highly resistant to UV radiation, soil chemicals, and mechanical damage during installation, ensuring lasting performance throughout the life of the structure.

Biaxial geogrids distribute tensile load in two directions—longitudinal and transverse—making them ideal for retaining walls and slopes. Triaxial geogrids feature a triangular rib structure that spreads load radially in multiple directions, providing superior confinement of aggregate and making them especially effective for road base and pavement stabilization applications.

Geogrids are used in a wide range of civil infrastructure applications including paved and unpaved road construction, parking lots, retaining walls, GRS slopes, bridge abutments, railroads, airports, mining and logging access roads, landfill construction, and wind farm developments. They are effective wherever soft subgrade conditions or load distribution challenges exist.

By reinforcing the subgrade, geogrids allow engineers to reduce the required aggregate or subbase thickness—sometimes significantly—without sacrificing structural performance. This lowers material procurement costs, reduces haulage requirements, and simplifies construction. The long-term performance of the reinforced structure also reduces maintenance and rehabilitation costs over time.

Yes. The geogrids supplied by Coleman Moore Company meet DOT-compliant specifications and satisfy project performance requirements for civil and environmental applications. They are suitable for use on state and municipal transportation projects throughout Iowa and are regularly specified by engineers and Departments of Transportation for road and infrastructure construction.
