The High Battery Stone Revetment Repair Project was an erosion control repair work project and consisted of the installation of approximately 8,000 tons of stone and 7400SY of geotextile fabric at the existing seawall and extending 40ft into Charleston Harbor. The repair work extended 1375ft along the Battery and was performed by barge. All work was tidal and involved close attention to tidal cycles. SJ Hamill’s stone was produced in a quarry in Kershaw, SC and then transported by over-the-road trucks to SJ Hamill’s yard in Charleston, SC where the material was staged prior to being loaded and transported by material barge to the High Battery location. In order to speed production, SJ Hamill innovated a geotextile jig for faster and easier fabric placement.
