Cement-free precast product
From January 2022, every product manufactured by SigmaRoc’s precast product group (PPG) will be available in a cement-free low-carbon option. Products in the group include Allen Concrete Ltd, CCP Building Products Ltd and Poundfield Precast Ltd.
The announcement follows the production 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 all sites across the country to minimise carbon emissions throughout the supply chain.
