Geogrid for Road Construction & Reinforcement

Geogrid pricing varies based on product type (biaxial vs. triaxial), project size, and site conditions. While there is an upfront material cost, geogrids typically deliver significant savings by reducing aggregate or subbase thickness requirements and cutting overall construction costs.

Placement depth affects how effectively the geogrid redistributes load and restrains aggregate lateral movement. When positioned at the subbase-subgrade interface, it provides maximum stabilization of weak soils. Placement within the base layer enhances load distribution and reduces tensile stress at the pavement's bottom, directly improving rut resistance and extending pavement life.

Biaxial geogrids reinforce soil in two directions — longitudinal and transverse — making them ideal for load support beneath roads and embankments. Triaxial geogrids feature a triangular aperture shape that distributes load radially in multiple directions, providing superior in-plane stiffness and confinement efficiency for unpaved roads, working platforms, and soft subgrade applications.

Geogrids benefit a wide range of projects including paved highways, unpaved rural and access roads, parking lots over soft subgrades, mining and logging haul roads, airport aprons, and railroad trackbeds. They are especially valuable where subgrade soils are weak, cohesive, or variable, delivering structural improvement without excessive aggregate or subbase fill.

Yes. The geogrids supplied by Coleman Moore Company meet DOT-compliant specifications and are suitable for use on state and municipal transportation projects. Products from manufacturers such as Tensar and Huesker are engineered to meet civil and environmental performance requirements, and Coleman Moore can assist with specification matching for your specific DOT project requirements.

Geogrid installation is straightforward. The geogrid roll is unrolled over the prepared subgrade or existing base, oriented correctly per design specifications, overlapped at seams, and pinned or staked as needed. Aggregate is then placed and compacted on top. Coleman Moore provides full installation consultation to ensure proper placement, overlap, and compaction procedures are followed.
