Seagull Paddock, North Geelong - Bridges go high-tech

We have built two world first 100-year maintenance free bridges for Seagull Paddock in North Geelong.

We recognise the need for safe and accessible infrastructure to support our community and are delivering this project to help meet the needs of the local North Geelong community.

Made in Geelong, fibre reinforced geopolymer bridges, are the first of their kind and were developed through the first Procurement for Innovation project to be successfully tendered in Australia.

To encourage sustainable innovation in line with its community-led clever and creative vision, we tendered for a 100 year maintenance free pedestrian bridge in 2017. The tender invited companies to come up with solutions to the costly maintenance and waste problem associated with traditional bridges – usually made of timber, steel or concrete - which cost our organisation around $500,000 to inspect, repair, maintain and replace each year.

The winning submission came from a consortium including local manufacturer Austeng, Deakin’s cutting-edge Waurn Ponds Carbon Nexus facility and Australian engineering company Rocla. The consortium undertook research and then developed an innovative new combination of materials resulting in a novel building product made from geopolymer (comprising partly recycled materials) and reinforced with fibre, which is stronger and significantly longer lasting than existing products.

Pre-construction beam failure testing began in May 2019. The testing shows the geopolymer concrete beams with carbon or glass fibre reinforcing are 15 per cent stronger than traditional steel reinforced concrete.

The new bridges are now open to the public and we invite you to enjoy the improved access they provide.

We are planning upgrades to the final bridge in this area in the near future.  We will provide further communication as we progress further.
