A township near a major metropolitan area in the Northeast United States experienced a total slope failure that included a large section of new highway extension. GeoStabilization International® was hired to provide a turnkey Design/Construct/Warranty approach to repair the slope and roadway. A wall was constructed utilizing Geosynthetically Confined Soil® (GCS®) technology on an array of micropiles installed through the slope failure plane; allowing the roadway, shoulder, and guiderail to reconstructed. The project was completed in less than one week and matched the cost estimate that GeoStabilization submitted prior to the project’s authorization.
In the 1970s, a massive rockslide buried Interstate 81 in Montgomery County, VA while it was being constructed. The mountain of debris took months to clear. More recently, VDOT engineers and geologists noticed active movement near the historic slide, and proactively began an emergency rock slope mitigation effort.
