Geogrids are used to reduce the thickness of the fill material, but also to increase the bearing capacity of the subsoil. The openings of the geogrids contribute to the interlocking of the aggregates, allowing effective reinforcement and stabilization of the soil. They offer time savings in construction thanks to their ease of application, but also savings thanks to the reduction of the amount of filling material required. They reinforce the structure in granular soils thanks to their high tensile strength.
