Targeted Subgrade Stabilization for Canadian Rail Corridors<\/b><\/h4>\n

RailJET\u00ae<\/b><\/h2>\n

GeoStabilization International delivers advanced ground improvement solutions for rail infrastructure<\/a> across Canada. RailJET\u00ae is GSI\u2019s patent-pending jet-grouting\u2013based technology engineered specifically for railway environments where access constraints, limited track windows, and long-term performance are critical.<\/span><\/p>\n

Designed for freight, passenger, and industrial rail systems, RailJET\u00ae strengthens soft or underperforming subgrades with minimal surface disruption. The system is particularly effective in corridors affected by glaciated soils, saturated deposits, seasonal freeze\u2013thaw cycles, and remote access limitations.<\/span><\/p>\n

What Is RailJET\u00ae?<\/b><\/h2>\n

RailJET\u00ae is a modified jet-grouting process that stabilizes railroad subgrades by mixing in-situ soil with a cementitious slurry. Using high-pressure horizontal fluid jets, the system forms soil-cement columns beneath the track structure.<\/span><\/p>\n

Mounted on a Hi-Rail platform, RailJET\u00ae can be deployed directly from the track without supplemental rail equipment. This allows crews to operate efficiently within restricted work windows and in locations where traditional excavation would be disruptive or impractical.<\/span><\/p>\n

The resulting soil-cement columns, typically 8 to 16 inches in diameter depending on subsurface conditions, reinforce the subgrade in both bearing and shear. The process also fills ballast pockets, improving load distribution and track uniformity.<\/span><\/p>\n\t\t\t\t<\/div>\n\t\t\t<\/div>\n\t\t<\/div>\n\t<\/div>\n<\/section>\n\n\n\n\n

How RailJET\u00ae Works<\/h2>\n

RailJET\u00ae improves subgrade performance from within the existing track structure by creating engineered soil-cement reinforcement zones beneath active rail lines.<\/p>\n
