CGC Dredging is a medium sized specialist dredging company, first formed in 1980, which has since evolved to suit the wide range of requirements of the Western Australian dredging industry. The company does most of the maintenance dredging for the Department of Transport (WA). It also serves the wider general marine industry. It performs specialist dredging for the mining community, mostly in the area of tailings management. For example, the company has undertaken all of Alcoa’s dredging work in WA for the last 20 years. It has four dredging units of various sizes and configuration as well as a wide range of support equipment.
