InfillPlus

InfillPlus® offers a unique combination of engineered timber and bonded fibre cement

Engineered for Performance and Safety

Designed in compliance with AS/NZS 2269 and third-party verified by Advanced Bridge Engineering Systems, InfillPlus® ensures that every project benefits from reliable structural integrity. The addition of a 4.5mm fibre cement sheet protects against timber fibre breakdown, prevents blockage of girder drainage ports, and reduces the risk of tannin staining on concrete surfaces.

OUR STORY

About InfillPlus

Infill panels like Big River InfillPlus® are designed to fit into the top of concrete girders, allowing cast in situ decking installation while preventing concrete from entering the girder tub.

At roughly half the weight of all-fibre cement or steel alternatives, InfillPlus® makes handling and installation easier, without sacrificing strength.

Engineered for slip-resistance and tested for dynamic loading, InfillPlus® provides a reliable platform for workers, improving jobsite safety.
