Fortrac Geogrid for Soil Reinforcement

Biaxial geogrids reinforce soil in two directions — longitudinal and transverse — making them ideal for retaining walls and slopes. Triaxial geogrids feature a triangular aperture pattern that distributes load radially in multiple directions, offering superior in-plane stiffness for roadway base stabilization and subgrade improvement over soft soils.

Fortrac geogrids interlock with aggregate to spread loads and reinforce weak subgrades, allowing engineers to specify thinner base course layers. This directly reduces material quantities, hauling costs, and construction time, resulting in lower overall project costs while meeting or exceeding design performance requirements.

Yes. Fortrac geogrids meet DOT-compliant specifications and are engineered to satisfy civil and environmental project performance requirements. Coleman Moore Company works closely with Iowa DOT contractors and engineers to ensure specified products align with applicable standards and project documentation needs.

Fortrac geogrids are manufactured from polypropylene, with some configurations incorporating HDPE. These synthetic polymer materials provide high tensile strength with low strain, chemical resistance to soil contaminants, UV radiation resistance, and durability against mechanical damage — ensuring permanent, long-term performance in the field.

Geogrids are well-suited for roadway and parking lot construction over soft subgrades, retaining walls, reinforced slopes, bridge abutments and approaches, railroad and airport infrastructure, landfill access roads, and mining or wind farm site access. Virtually any project involving weak or unstable soils can benefit from geogrid reinforcement.
