Cannelton Hydroelectric Project

April 2011 at Hawesville, Kentucky, USA


Method Applied

Bottom Feed Stone Columns

Average Depth


For the Cannelton Hydroelectric Project Stone Columns had to be installed up to 70 ft (≈ 21 m) into an existing slope. Loader access was impossible. Betterground’s Gravelpump was used to transport the gravel to the stone column rig that operated in the slope. Columns were installed to increase slope stability by preventing soil liquefaction due to earthquakes that would originate from the close by New Madrid EQ zone.
