GCS® Wall With Micropile Foundation


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 repairing the slope and roadway. A Geosynthetically Confined Soil (GCS®) Wall was constructed on an array of micropiles installed through the slope failure plane, which allowed 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.
