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. GSI® 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. This configuration, coupled with the shotcrete wall, provided a robust foundation for a GeoSynthetically Confined Soil (GCS®) Wall. The GCS® Wall re-established the roadway width, shoulder, and guardrail area that existed prior to the slope failure.
In the Mid-Atlantic Region of the United States a rockslide occurred that presented a variety of problems for the state’s Department of Transportation (DOT).
