Star Drilling undertook this multiple rig program using both conventional geotechnical methods and sonic drilling to investigate the water side of the Hume Weir Earthen Wall.
The project required drilling into waste emplacement areas to a depths ranging from 70 m to 117 m at the Duralie Coal Mine Site NSW. The previous drilling contractor was unable to reach required depths
Star Drilling spent three years geotechnical drilling for the Melbourne Airport Rail Link. A lot of drilling occurred on or under the E.J. Whitten Rail Bridge.
