Reduce track settlement and extend ballast life with GEOWEB® ballast stabilization
The GEOWEB System is engineered to stabilize railway ballast over soft or variable subgrades. By confining ballast within a 3D cellular structure, the system increases overall track stiffness, minimizes differential settlement and enhances the ability of the rail to support heavy freight loads with improved performance and reliability.
The system improves lateral and vertical ballast confinement to limit aggregate movement, rotation, and abrasion. Compared to geogrids or hot mix asphalt layers, GEOWEB distributes stress more evenly, providing a long-term solution for problematic track beds and high-stress rail areas.
Performance has been validated through third-party research and large-scale field testing at TTCI, Oregon State University, and the University of Kansas. Results show reduced track displacement, lower maintenance needs, and extended ballast life in challenging conditions.

Ballast Stabilization Solutions
Railway engineers worldwide have relied on GEOWEB long-term confinement to create high stiffness foundations under track and high stress areas such as bridge abutments, diamonds and turn-outs. The GEOWEB system is extremely effective in stabilizing track sub grades and limiting differential and long-term settlement.
