SigmaRoc to offer cement-free alternative for all precast concrete products

From January 2022, every product currently manufactured by SigmaRoc's Precast Product Group (PPG) –  Allen Concrete, CCP Building Products and Poundfield Precast – will be available in a cement-free ultra-low carbon option.

The announcement follows the launch of Greenbloc – a cement-free alternative to ordinary Portland cement (OPC) blocks – in February 2021.

The cement-free range, which also extends to bespoke solutions, will be manufactured at SigmaRoc's five sites located across the UK. The company says this will provide the broadest geographical reach of any precast concrete product supplier in the country, while also minimising carbon emissions throughout the supply chain.

Michael Roddy, managing director of Sigma Roc PPG, comments: “Greenbloc set the bar for bringing a cement-free alternative to a traditional building material into mainstream use, but it was only ever the start of our low-carbon journey."

Roddy says that the benefits of using cement as a building material are undisputed from an application perspective, however the carbon required in the manufacturing process cannot be ignored.

He adds: “Our aim is simple. The market is changing and understands the need to acknowledge, address and action a tangible approach to decarbonisation. We want to give architects, contractors and specifiers the choice of using an ultra-low carbon cement-free alternative to precast cementitious products."

Roddy says that the new announcement is the next step on SigmaRoc’s journey of investing, improving and integrating to deliver maximum value to customers and shareholders, and ultimately providing a greener way to build. "Not just infrastructure, but our own future,” Roddy states.
