A Mid-Atlantic state’s Department of Transportation (DOT) and its historical preservation group wanted to repair and rehabilitate a failing rock wall within a town in Appalachia. The mandate was to restore the wall to its original appearance. This project languished for years while contractors and key players tried to determine the best way to achieve this mandate.
GeoStabilization International®, who has some of the top rock masons in the United States, inspected the site and provided a repair design to the DOT. A letting based upon GeoStabilization’s design was advertised and GeoStabilization was low bidder by 30%.
Upon commencement of work the wall facing was carefully removed and stockpiled. GeoStabilization’s crews then installed an array of SuperNails® to stabilize the wall backfill.
Next GeoStabilization’s masonry team got to work rebuilding the rock face and stone guardrail on the newly stabilized structure. After the project’s completion the DOT’s construction office and the state’s historical preservation group commended
GeoStabilization for their superior workmanship.
