TESTING
​
Murray Gilbertson holds BE(Civil)Hons and MBA qualifications. His background includes diverse national engineering projects and he has held several senior executive roles. In these roles asset management was a key focus to cost effectively improve the service life of essential structures.
Research work by Murray and his associates has led him to, alongside these other professionals, finding improved techniques to protect concrete coastal structures. G-Group's work has involved many wharf and coastal structures where chloride attack and other deterioration processes are active.
Our leading work on investigating penetrating hydrogel performance for internally protecting concrete structures, both existing and new, is having a positive impact across various structures including wharves, bridges and buildings.
