Envirogrid can significantly reduce the amount and/or quality of aggregates required to stabilize a poor load bearing soil. The cell walls keep the aggregates from being pushed away from the applied load. Because the filled cells are connected together, the panel acts like a large mat. Applied loads are spread over an extended area instead of directly at the point of contact. Due to the high costs and environmental concerns of mining quality aggregate and, in many cases, the significant expense of hauling aggregates over long distances, engineers are specifying the GeoProducts geocell to save costs in many ground stabilization projects.
