Wagners’ ‘world first’ shows shotcrete strengths



The Wagner Group has released its Earth Friendly Shotcrete in a pioneering step for zero carbon concrete with applications in ground stabilisation, tunnel linings and pools.

Using Wagners’ patented Earth Friendly Concrete (EFC) low carbon technology, the Earth Friendly Shotcrete (EFS) was used commercially to construct a swimming pool.

The pool was part of a housing project by Stewart Homes and Fowke Design and Constructions in Raby Bay, Queensland.

Stewart Homes director Ian Henry said the low carbon qualities of this job were integral for the client.

“For this build the client specified that we needed to use building materials with significantly reduced embodied carbon, and Earth Friendly Concrete by Wagners is the only cement free product on the market,” Henry said.

The EFS can be used to save about 250kg of embodied carbon dioxide per cubic metre of product compared to standard concrete.

Wagners EFC general manager Jason Zafiriadis said projects like the housing development were a great showcase of the product’s wider applications.

“Our technology demonstrates genuine environmental benefits, and this project was an opportunity for us to demonstrate the effectiveness and functionality of Earth Friendly Shotcrete,” Zafiriadis said.

Shotcreting is the process of applying concrete to a surface at velocity and the EFS is well suited due to its heightened “stickiness”, Wagners claimed.

The EFS also contributed to the circular economy of building products as it creates a use for their waste.

Fowke Design and Construction director Wally Fowke said he welcomed the use of this world first product under his watch.

“Earth Friendly Shotcrete has a similar application to traditional shotcrete, and we are pleased to be the first company to use this new product in Queensland,” Fowke said.
