Presto’ GEOWEB® 3D system is a 35-year proven solution for stabilizing and reinforcing track subballast. By confining and strengthening infill material, the system’s 3D cellular structure reduces ballast depth requirements by 50%. Rigorous research and testing showed significant reductions to settlement and track displacement under heavy freight loading over very soft subgrades. The GEOWEB system controls long-term differential settlement superior to geogrids or Hot Mix Asphalt (HMA) and offers significant benefit for track subgrade and high impact areas: diamonds, crossings and bridge approaches. The GEOWEB system is also effectively employed for slope stabilization and retaining walls in right-of-way areas.
