Presto's GEOWEB® system is a 30-year proven solution for stabilizing track subballast over soft subgrades. By confining and strengthening infill material, the system's 3D cellular structure reduces ballast depth requirements by 50%. The high-strength system, tested and proven at AAR-TTCI, Oregon State University (OSU) and University of Kansas (KU) showed significant reductions to long-term differential settlement and to track displacement under heavy freight loading over very soft subgrades. Significant benefit is delivered for track subgrade and high impact areas such as turn outs, diamond crossings and bridge abutments. The GEOWEB system is also effectively employed for slope stabilization and retaining walls in right-of-way areas.
