In 2008 Murray founded his consulting practice G-Group located in Hastings, New Zealand.
He holds BE(Civil)Hons and MBA qualifications. His background includes diverse national engineering projects and he has held several senior executive roles in central and local government. In these roles asset management was a key focus to cost effectively improve the service life of essential structures.
Murray’s research and investigation work has led him to, alongside other professionals, finding improved techniques to protect concrete coastal structures. His work has involved many wharf and coastal structures where chloride attack and other deterioration processes are active.
His 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. He has presented at many conferences and forums within New Zealand and Australia on concrete deterioration over the last 8 years.
Long Term Internal Protection of Concrete Structures Using Hydrogel Formations
Coastal concrete structures exhibit up to 10 times more rapid deterioration than inland structures. Surface coatings are not delivering the longer-term protection sought by asset owners and cathodic protection often proves difficult with existing structures. Murray will share recent developments of penetrating hydrogels and admixtures, including outlining an investigation across six existing deteriorating wharf structures that were treated with a penetrating hydrogel and the consequential waterproofing and chloride reduction findings.
