Working adjacent to active rail requires safety certifications, equipment clearance verification, and work window coordination that civil geotechnical subs without railroad experience can't provide without substantial training investment and risk to your track possession schedule. When the possession window is two to four hours and the scope must be completed before trains resume, your sub needs to have done this before.
GeoStabilization International has deployed on Class I carrier, commuter rail, and freight railroad projects across North America. Our crews hold current roadway worker protection certifications, equipment clearances are maintained annually, and our field supervisors coordinate work window entry and exit directly with track supervisors. Your possession is used — not wasted on setup and certification issues.
GeoStabilization International provides specialty geotechnical subcontract services for railroad contractors — embankment stabilization, rockfall mitigation, track subgrade improvement, and emergency response — with the track safety credentials and equipment clearances your carrier requires.
Embankment failures and slope sloughing on railroad rights-of-way are repaired through soil nail and tieback systems installed by GSI crews during track possessions or from off-track positions, designed to avoid track geometry disturbance during installation.
The RailJET™ system injects grout beneath the rail subgrade to densify ballast and sub-ballast without requiring track removal. The injection system fits between rail ties and operates during possession windows — restoring subgrade stiffness without removing a single tie.
Rock faces adjacent to rail corridors are stabilized through catch fence, draped mesh, rock bolt, and scaling programs installed from either the right-of-way or from track-mounted access equipment during scheduled possessions.
Track subgrade improvement has traditionally required a full track pull-out and ballast replacement program — expensive, time-consuming, and possession-intensive. GeoStabilization International's proprietary RailJET™ system provides a third option: injecting grout beneath the subgrade from between the ties during a standard maintenance possession, restoring bearing stiffness without removing a single tie.
On corridors where ballast replacement cost and possession time are prohibitive, RailJET™ grouting has extended the service life of treated track sections while reducing geometry surfacing frequency — a technology advantage no other geotechnical sub can offer.
