Protection of the state’s biggest ever rail infrastructure investment from carbonation and graffiti

Material & Application

ecotio₂ applied to the structures smooth off-form precast concrete


The coated concrete parapets remain as new with no streaking, black particulate or mould present in addition to graffiti resistance. The concrete’s ability to naturally  self-clean because of the photocatalytic properties of ecotio₂ is such an important sustainability story that contributed to the project winning the 2020 ENR’s Global Best Rail Project Award.


We are incredibly proud to have been awarded this global honour. Sydney Metro Northwest truly demonstrates what can be accomplished when we connect our thinking between global expertise and local knowledge. We thank everyone who played a part in delivering this project which has helped lay the foundations for a new era in public transport in Australia.
