Star Drilling has worked multiple rigs with GHD for two years drilling geotechnical bores for the three possible routes of the Northeast Link.
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.
