GeoStabilization International® received a call to assist with an emergency roadway landslide. The slope failure had destroyed the outbound lane right up to the centerline, causing the lane to sink 28 feet and resulting in a total road closure.
GeoStabilization immediately mobilized its emergency response crew for a no-cost, no-obligation visit to the location. In emergencies, the company can often have technicians working on-site within 48 hours after the initial slope failure. In the case of roadway landslides, road corridors can typically open to traffic within the week.
After surveying the site, GeoStabilization’s engineers submitted a guaranteed fixed-cost design proposal to the client. The recommended solution involved a combination of the company’s proprietary SuperNails™, reticulated SuperMicropiles™, Geosynthetically Confined Soil® (GCS®), and reinforced shotcrete to contain the ground movement and permanently stabilize the slope.
To start, GeoStabilization’s technicians installed multiple rows of SuperNails™ and reinforced shotcrete to stabilize the collapsed section from above and create temporary access benches.
GeoStabilization’s proprietary launched SuperNails™ stop movement in shallow landslides without excavation, fluids, drill cuttings, or significant environmental disturbance. This method typically requires the closure of only one traffic lane, which translates into substantial time and cost savings compared to conventional slope stabilization techniques.
Next, the crews installed reticulated SuperMicropiles™ with a reinforced concrete cap at the bottom of the repair. These structures, coupled with a shotcrete wall, served as the foundation for the GCS® wall that re-established the roadway’s original width, shoulder, and guardrail area.
Upon completing the construction, GeoStabilization issued an extended warranty covering not just the materials and installation but also the stability of the repaired roadway. No other provider can match GeoStabilization’s warranty guarantee.
The engineers at GeoStabilization International® use the most advanced methods and technologies to evaluate and improve slope stability. At any given time, the company’s teams participate in several public or private research projects and incorporate this research and the latest soil stabilization innovations into their work.
GeoStabilization International® maintains a 3:1 ratio between field technicians and geotechnical engineers on all sites and continually trains site superintendents in the latest construction and landslide repair techniques. This way, the engineering staff can receive constant feedback on site conditions and implement the most effective solutions.
With over 5,500 landslides fixed to date, GeoStabilization International® provides turnkey engineered solutions that effectively stop active landslides and permanently stabilize slope erosion. All solutions are backed by a multi-year performance warranty.
The company stockpiles materials and maintains a 24/7 emergency response capability across the U.S. and Canada. As a result, critical infrastructure can often reopen in days, not months, which translates into significant time and cost savings.
