Railway Stabilization & Reinforcement



Railroads are high demand transportation structures that must remain in service to maintain high profitability.  

Geopier® has a multitude of ground improvement solutions to make sure both new and existing tracks can operate at full capacity.  

The Geopier GeoSpike℠ and SRT® railway foundation stabilization systems are ideal for maintenance applications, offering minimal disruption to service.  

Our Rammed Aggregate Pier® systems are ideal for new track construction, making sure the railway reinforcement performs as intended for its service life.

Track Subgrade Repair

For track maintenance applications, the Geopier GeoSpike℠ system is a rapidly installed, low-cost method for strengthening weak railroad track subgrades. This minimally invasive system consists of installing stiff HDPE elements between ties to transfer track loads through weak subgrade soils and into competent bearing soils.  These elements can be installed without removing railroad tracks, ties, or ballast.

Slope Stability

The Geopier SRT® an be used to stabilize slopes on existing railway embankments that experience shallow slides.  The SRT system is ideal for constrained right of ways and eliminates the need for massive earthwork and site disruption.

New Railroad Construction

Geopier Rammed Aggregate Pier® (RAP) systems can be used to strengthen soils below new tracks, embankments, and retaining walls.  The high stiffness of the Geopier elements reduces short-term and long-term settlement (eliminating lengthy preload periods) and increases the factor of safety against global instability.

Partnering with Tensar
