A Department of Transportation in the Midwestern U.S. contracted GeoStabilization International® to mitigate a series of landslides on the slopes near a rail spur bridge.
Conventional soil stabilization and landslide mitigation solutions were not feasible in this case, due to severe access restrictions, so GeoStabilization designed an innovative solution.
By launching SuperNails™ faced with reinforced shotcrete in a horizontal drain array, the company’s crews were able to halt the active ground movement and prevent further landslides without excavations or interruptions of bridge and railroad traffic.
Soil nailing is a soil retention and stabilization method in which reinforced hollow bars are inserted in the soil mass. Conventional soil nailing uses standard equipment to drill or drive nails into the ground. However, GeoStabilization’s proprietary Soil Nail Launcher™ uses compressed air to launch SuperNails™ at speeds reaching 250 mph. This innovative process enables rapid installation and minimizes track downtime without interrupting regular train flow.
The excavator-mounted Soil Nail Launcher™ is part of GeoStabilization’s fleet of purpose-built drill rigs for limited access sites, which also includes helicopter-mobile wagon drills, “walking” spider excavators, crane-basket mounted drills, and more. No landslide mitigation company in North America has a larger or more diverse fleet that allows it to reach even the most remote and hard-to-access sites.
RailJET® is one of GeoStabilization’s most innovative solutions for railroad soil stabilization. This modified jet grouting technique involves the injection of a horizontal jet of fluid into the soil mass to create a soil-cement reinforcing column. RailJET® has been critical to the success of numerous railroad landslide stabilization projects.
GeoStabilization International® stocks equipment nationwide and maintains a 24/7 emergency response capability. As a result, the company is often able to dispatch an engineer or representative immediately for a no-cost, no-obligation visit to affected areas.
After surveying a site, GeoStabilization sends a guaranteed fixed-cost proposal. If the client agrees, crews can often start working within 48 hours after the initial slope failure.
Upon completion of the project, GeoStabilization issues a full warranty that covers not just the materials and installation but also the site’s stability. No other company matches GeoStabilization’s extended warranty guarantee.
With over 5,500 landslides fixed to date, GeoStabilization International® is the undisputed leader in geohazard mitigation. This stellar track record includes over two decades of experience in railroad stabilization projects across the U.S., Canada, and Australasia.
Thanks to GeoStabilization’s innovative equipment, advanced technologies, and skilled engineers, the company can deliver rapid installations and high mobility in limited-access sites.
Track closures are minimal or nonexistent, enabling trains to run on schedule, and the project often costs twice less and has a lower environmental footprint than conventional slope stabilization methods such as piling, caissons, and retaining walls.
