New range of bricks from Marshalls lock in carbon

Marshalls Bricks and Masonry has launched a new range of concrete facing bricks which utilise carbon sequestration technology to lock in waste CO2. 

The new collection – known as the Glenwall range – has been developed at the company's site in Grove, Wales and incorporates cutting-edge CarbonCure technologies. During the production process, waste CO2 is directly injected into the concrete mix causing the CO2 to mineralise and become permanently locked into the brick, preventing its release into the atmosphere, even when it is demolished. Marshalls estimate that the use of CarbonCure at the Grove site will remove approximately 30,000kg of CO2 annually.

Mike Edwards, head of sustainability at Marshalls, said: "We became the UKs first pre-cast concrete manufacturer to adopt CarbonCure processes back in 2022 and, following a number of successful trials, we began applying the technology to existing ranges last year. Glenwall is our first new facing brick range to contain locked-in carbon; it’s bringing more choice to the market both in terms of aesthetics and sustainable options.”

Glenwall bricks come in four traditional colours including: Grosmont Cotswold – light neutral buff; Pembridge Terracotta – deep vibrant red; Stokesay Chestnut – a multi-tonal earthy red and Machen Pewter – with blue-grey tones. They are also frost-resistant, offer Euroclass A1 fire resistance and can withstand weathering.
