GeoStabilization International® responded to an emergency road closure where a landslide destroyed the outbound travel lane right up to the centerline. The lane dropped down 28 vertical feet and forced a complete road closure. GeoStabilization’s crews installed multiple rows of SuperNails® and reinforced shotcrete to stabilize the site from above and from temporary access benches. Next, reticulated SuperMicropiles™ were installed at the bottom of the repair and encapsulated with a reinforced concrete cap. These initial tasks, coupled with the shotcrete wall, provided a robust foundation for the Geosynthetically Confined Soil (GCS™) Services which were then utilized for the repair. A wall re-established the roadway width, shoulder, and guardrail area that existed prior to the slope’s failure.
