First new brick range incorporating carbon sequestration technology

Marshalls Bricks and Masonry has unveiled a new range of concrete facing bricks, which have been manufactured using innovative carbon sequestration technology to lock in waste CO₂.

The Glenwall range incorporates cutting-edge CarbonCure technologies, a ground-breaking process employed at the Marshalls site in Grove, Wales. This technology injects waste CO₂ directly into the concrete mix during production, with no negative impact on the performance or durability of the brick.

As a result, the CO₂ becomes mineralised and permanently locked into the brick for millennia, preventing its release into the atmosphere, even upon demolition. It is estimated 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.”

The range introduces a rusticated texture, adding depth and character to architectural designs while offering unparalleled sustainability. It is available in four traditional colours, each meticulously crafted to blend seamlessly with various architectural styles and preferences.

• Grosmont Cotswold: A light neutral buff
• Pembridge Terracotta: A deep vibrant red
• Stokesay Chestnut: A multi-tonal earthy red
• Machen Pewter: A striking blue-grey

Beyond their aesthetic appeal and environmental benefits, Glenwall facing bricks boast exceptional durability. They are frost-resistant and offer Euroclass A1 fire resistance, ensuring the utmost safety in construction projects. Additionally, Glenwall bricks exhibit remarkable resistance to weathering, maintaining their structural integrity and visual appeal over time.

With its reduced carbon footprint, Glenwall concrete facing bricks emerge as a superior alternative to conventional clay bricks, aligning with Marshalls Bricks and Masonry's commitment to sustainability.
