for railroad soft-subgrade soils stabilization

An Inside Look at our RailJET®

RailJET® is a patent-pending technology that utilizes a modified jet grouting process explicitly intended for railroad soft-subgrade soils stabilization, for stiffening super-elevated curves, and improving bridge approach subgrades to limit excessive dynamic loading onto the bridge structure. The Hi-Rail mounted equipment uses a high-pressure, horizontal jet of fluid to mix existing soil with a cementitious slurry. Used in areas with limited track windows or where extensive earthwork would be impractical or impossible, RailJET® is ideal for limited access areas and rapid emergency stabilization necessitated by track settlement or sinkhole formation.

A hydrodynamic mix-in-place technique producing a soil-cement column, RailJET® improves/reinforces the soil both in bearing and shear. The diameter of each column is dependent on actual in-situ soil conditions, but generally ranges from 8 to 16 inches. The process also inherently fills ballast pockets where they exist.

Benefits of RailJET® in Your Projects

  • Reduces embankment settlement & lateral spreading
  • Fills ballast pockets with grouted soil/cement
  • Stiffens bridge approaches thereby reducing dynamic loading on bridge structure due to approach settlement
  • By stiffening subgrade, helps to maintain track curvature geometry in superelevations
  • Increases track modulus
  • Provides shear resistance for typical railroad loadings
  • Increases longevity of railroad infrastructure
  • Reduces long-term and ongoing maintenance costs
  • Is often used in conjunction with trench drains

Why Choose RailJET®

  • Self-contained system, additional equipment from railroad is unnecessary
  • RailJET® quickly egresses active track, allowing for increased work durations and flexibility
  • 90% of grout material is utilized, reducing waste and lowering repairs’ cost
  • Can be deployed in the most remote locations
