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.
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.
This program involved drilling PQ3 bores down to a maximum of 150 metres and required quality core from the alluvial sediments.
