The two companies said they will pool their knowledge and work together to develop new ultra-low carbon methods of production.
AIM-listed SigmaRoc (AIM:SRC) launched the world's first cement-free block in 2021 and has committed to manufacturing a cement-free alternative to every product within its precast product group from next year.
Michael Roddy, Managing Director of SigmaRoc's Precast Product Group said: "With the construction industry increasingly recognising the importance of integrating low-carbon alternatives into future ways of working, we are delighted to begin our strategic collaboration with Marshalls (LSE:MSLH)."
"To date, SigmaRoc has focussed on developing scalable, low-carbon solutions for major infrastructure work. However, we recognise that residential and urban environment projects represent a significant portion of UK construction activity so we are excited at the prospect of working alongside Marshalls to help develop these solutions.”
Nick Jowett, Technical Director at pavings stone specialist Marshalls added: "By entering into a collaboration with SigmaRoc we envisage being able to give our customers the opportunity to use an ultra-low carbon alternative to a variety of traditional hard landscaping and construction products."
