Engineered Nature Crossings
Precast Arch Solutions


Background
Fauna and Flora Crossings for Environmentally Sensitive Areas
The Humes Bebo Precast Concrete Arch system is increasingly used across Australia for fauna and flora crossings. Its modular design allows for fast and safe installation, reducing site disturbance, an essential benefit in environmentally sensitive areas. Available in every state and territory, the system can be custom-designed to meet a wide range of project needs.
Key Challenge
Balancing Ecological Sensitivity with Construction Efficiency
Fauna and flora crossings require solutions that minimise environmental impact during construction. Traditional in-situ methods can extend project timelines, create unnecessary site disturbance, and increase long-term maintenance demands. Projects needed a durable, low-maintenance system that could be rapidly deployed while meeting strict environmental requirements.


Delivering the Solution
Precast Arches Designed for Durability and Sustainability
Precast concrete provided a faster, safer, and more consistent solution compared to in-situ alternatives. The Humes Bebo Arch can be tailored in size and finish, with fittings incorporated during production for project-specific enhancements.
To support sustainability targets, Humes incorporates up to 50% supplementary cementitious materials (SCMs) including flyash and slag reducing embodied carbon while maintaining long-term durability. This approach ensures the Bebo Arch delivers strong environmental performance alongside efficient construction outcomes.
