During installation of a double-line grout curtain at Wolf Creek Dam, the U.S. Army Corps of Engineers used sonic drilling to install the holes through the embankment. This method of drilling provides several benefits over drilling using fluids, says Michael F. Zoccola, chief of the civil design branch of the Corps.rnSonic drilling involves the use of high-frequency resonant vibration to advance a core barrel into a structure, Zoccola explains.
