Cemvision, the Swedish green cement producer, has announced one of the UK’s first known commercial deployments of high-performing low-carbon cement, at a Sunbury development of STOREX Self Storage, the self storage business of real estate manager EQT Exeter. This marks a precedent towards greener building practices in the UK, as Cemvision begins its strategic expansion into the market. Cemvision and STOREX have signed a Letter of Intent for multiplied use of Cemvision’s products in the UK and other markets. “The Cemvision product stands out. We’re pleased to have found it,” says Jack Sindhu, Technical Director for London-based leading UK concrete company Capital Concrete.

In Sunbury, Cemvision is deploying its innovative Re-ment technology for the development of foundational slabs, using Re-ment Massive to replace traditional Portland cement. Recent testing conducted at Sandberg’s concrete laboratory demonstrated exceptional performance results, including 28-day compressive strength reaching the C50/60 classification and a 75% CO₂ reduction compared to Portland cement. These results establish Cemvision as a ‘market-beating’ solution under the UK 2024 LCCG Benchmark, setting a new standard for sustainable and high-performing construction materials.

“This project is a landmark achievement for Cemvision as we bring the benefits of green cement to UK customers,” says Oscar Hållén, CEO of Cemvision. “Working alongside STOREX and leading technical partners in architecture, engineering, and planning, we are committed to showcasing the scalability and climate benefits of our technology in the UK market.”

The full-scale application at the STOREX site is a partnership in a multi-disciplinary team, including Capital Concrete, Aztec Construction, ROK Planning, Threesixty Architecture, Will Rudd and Atelier Ten. STOREX’ owner EQT Exeter is a leading global real estate investment manager.

London-based ready-mixed concrete producer Capital Concrete has been at the forefront of new technologies and low-carbon concrete solutions. Jack Sindhu, Technical Director for Capital Concrete, says: ‘The Cemvision product stands out. It is easy to batch, works seamlessly with traditional aggregates and admixtures, and consistently achieves the right consistency and specified characteristic strength. We’re pleased to have found it.”

The Cemvision Re-Ment Massive technology reaches different levels of CO₂ reduction depending on application and local conditions. In Sunbury, STOREX is an early adopter and has undertaken extensive testing following BSI Flex 350 to achieve a performance-based specification. Cemvision has already achieved more than a 95% reduction compared to Portland cement in demo production, in the EU. The company forecasts its ability to achieve this also in the STOREX partnership, with future manufacturing and supply chain scenarios that will benefit from efficiencies in scale and reduced transport emissions.

STOREX and Cemvision sign Letter of Intent

The project also laid the foundation for Cemvision and STOREX to sign a Letter of Intent for further procurement of Re-ment.

“STOREX has an ambitious strategy for lowering embodied CO₂ emissions. Partnering with Cemvision is a vital step in achieving our sustainability goals cost-efficiently, while maintaining the highest standards in construction,” says Robert Grant, Senior Director, Investment and Development Self-Storage at EQT Exeter.

Cemvision launches strategic expansion to the UK market

The UK market represents a new strategic priority for Cemvision. Its cement market consumes more than 15 million tonnes annually, and the growing demand for low-emission solutions in the country positions it as a prime market for Re-ment. The country’s ambitious climate goals and dynamic market conditions create significant potential for Cemvision’s near-zero cement technology to become a critical component in reducing CO₂ emissions— and costs, as emissions gradually become more expensive.

“The UK market is central to our growth, not only due to its scale but also for its fast-moving approach and progressive stance on sustainable construction,” says Oscar Hållén, CEO of Cemvision. “We see an ideal environment for Re-ment to thrive here, offering an accessible and cost-efficient solution to industrial carbon challenges,” Hållén says. Performance facts Sandberg’s concrete laboratory for evaluation and compliance testing has independently assessed the application of Cemvision’s cement at STOREX Sunbury, with the carbon assessment conducted by Atelier Ten. Here are the results:

• Achieves 28-day compressive strength of 55–60 MPa, exceeding the C32/40 requirement and reaching C50/60 classification.

• With 70.35 kg CO₂e/m³ carbon emissions, Cemvision outperforms the UK 2024 LCCG Benchmark for its class (starting at 135 kg CO₂e/m³), earning a ‘marketbeating’ designation.

• Refining the mix design could meet C32/40 standards with reduced Cemvision Re-Ment Massive, further lowering cradle-to-gate emissions.
