Henley Stone Specialists, BCM GRC and Smart Crosby International (SCI) have joined forces to launch a single source solution for the full design, manufacture, supply, and installation of GRC wall cladding systems. Construction firm Henley Stone Specialists, the UK’s leading installer of high-grade Glassfibre Reinforced Concrete, BCM GRC Ltd, leading UK GRC manufacturer, and top engineering design specialists Smart Crosby International (SCI), have launched a comprehensive single source solution for the design, manufacture, and installation of Glassfibre Reinforced Concrete (GRC). This collaboration signifies a landmark moment for the UK GRC market, making the entire process more time-efficient and cost-effective for the end client. With over 90 years of combined experience within the UK GRC market and as long-standing members of the GRCA, this formidable trio already have a comprehensive track record of successfully and collaboratively delivering high-volume, top-quality, prestigious GRC cladding projects from design through to installation. With all aspects of the process provided by UK factories and offices, each company is an expert in their discipline aiming to offer clients an unrivaled package for GRC cladding requirements. The benefits of the collaboration are significant, providing more durability and minimal project maintenance, alongside a reduced construction phase and efficient delivery programme. In addition to this, GRC is a more sustainable solution for the environment, by significantly reducing carbon footprint due to a streamlined process. Shaun Henley, Founder and Managing Director of Henley Stone Specialists, commented: “We are delighted to be working alongside our partners BCM and SCI, this collaboration could be a landmark moment in the UK GRC construction sector. It is the first time a single-point solution for GRC has been offered to the UK market. With Henley Construction Management Group having recently launched our HZS stainless steel division the timing of the new venture is perfect. Our new division gives us the capability to produce our own, in-house stainless-steel brackets and fixings for all GRC projects. With our manufacturing capabilities and expertise in GRC installation, this joint venture will be sure to create more efficiencies and accuracy for our valued clients.” Darin Ballington, Director at BCM GRC Ltd added: “We’ve got a long-standing history of collaborating on projects with Henley Stone Specialists, so it seemed a natural fit to formally launch a new collaborative offering to the market – we’re excited to see what the future brings and to work on the highest of quality projects together.” John Dunthorne, Managing Director at SCI said: “We’re proud to be part of this new offering and the benefits it will bring clients across the industry. We will, of course, continue to work with other partners across the industry, but this collaboration will allow us to streamline specific joint projects and make them more cost-effective and efficient.”  Significant collaboration projects between Henley Construction Management Group, BCM, and SCI include the supply, design, and installation of GRC on the Halo Project – a 7-story 116,000 sq ft Grade A office in Bristol that received a BREEAM Outstanding rating, in addition to The Charterhouse, a 206,000sq ft office and retail development in Farringdon, and Brentford Block D, a mixed-use project which provided 102 new homes in central Brentford.

By Eve Pope, Technology Analyst at IDTechEx In a world with a growing population and a rapidly expanding construction sector to match, how do we prevent building homes from damaging our climate? Concrete is the second most consumed material on Earth, but its key ingredient, cement, is responsible for 7% of global anthropogenic CO2 emissions. The answer could come from thin air – CO2-derived building materials. The new IDTechEx report “Carbon Dioxide Utilization 2024-2044: Technologies, Market Forecasts, and Players” explores many ways to valorize captured carbon dioxide to create useful products. Among these, CO2-derived building materials showed particular promise due to performance improvements and cost-competitiveness, as well as sustainability benefits. IDTechEx forecasts over 170 million tonnes of captured CO2 will be utilized in building materials by 2044. Carbon dioxide can be utilized in concrete production in three different ways: injection of CO2 during curing of precast concrete, injection of CO2 during mixing of ready-mixed concrete, and formation of carbonate aggregates/additives Unlike some other carbon dioxide utilization pathways, such as the conversion to e-fuels, which requires large amounts of energy and green hydrogen (often prohibitively expensive), the basic mineralization chemistry underpinning the uptake of CO2 during concrete manufacturing is thermodynamically favored and less energy-intensive because stable metal carbonates are formed. These carbonates represent effectively permanent sequestration of CO2, so CO2-derived building materials double up as simultaneous carbon dioxide utilization and carbon dioxide storage. The process is compatible with many different sources of CO2. Valorizing waste In addition to waste CO2, solid waste streams can also be repurposed into new concrete using CO2 mineralization chemistry to form carbonates. For example, CO2-derived concrete players include Swiss company neustark, who uses the reaction of CO2 with demolished concrete to store carbon dioxide and produce concrete aggregate. Another aggregate producer, UK-based O.C.O Technology, instead uses CO2 and waste materials from industrial thermal processes. Meanwhile, building materials giant Heidelberg Materials has ongoing R&D into recycling concrete using CO2 to form a cement substitute. Steel slag is being explored by companies including Carbonaide and CarbiCrete as a cement replacement during CO2-aided curing. Additional revenue can be generated through waste disposal fees, with some CO2-derived concrete players reporting to having already achieved price parity with incumbents. Accelerating adoption Concrete production is typically low-margin, and willingness to pay a green premium is low. Therefore, widespread deployment of CO2-derived concrete will rely on CO2 utilization technology players, creating easy-to-adopt solutions that are minimally disruptive to existing manufacturing processes. In CO2-aided curing, some players have targeted retrofittable curing chambers. Elsewhere, plug-and-play and mobile unit solutions are also being commercialized. 2023 saw the release of several ASTM standards around CO2-aided curing, improving confidence in the safety and quality of CO2-derived precast concrete. While many CO2-derived building materials have yet to achieve price parity with conventional concrete, some customers are willing to pay a premium due to enhanced performance (such as higher strength and improved aesthetics). Going beyond net-zero The direct uptake of CO2 into concrete can be a net-zero process if the carbon dioxide is sourced from a fossil point source (such as a coal power station) or a net-negative process if biogenic or direct air-captured CO2 is used. In 2023, a collaboration between direct air capture (DAC) company Heirloom and CO2-derived concrete player CarbonCure stored CO2 captured from the ambient air into concrete for the first time. But is CO2-derived concrete still net-negative when considering the CO2 released during cement production? The formation of metal carbonates during CO2 mineralization can increase concrete strength and reduce the amount of cement needed. Alternatively, some carbonate additives can act as supplementary cementitious materials and replace cement. Therefore, according to IDTechEx’s analysis of players, several can produce carbon-negative concrete products. The permanent storage of CO2 into concrete enables players to sell high-value carbon dioxide removal credits on the voluntary carbon market. The way forward Although the production of CO2-derived concrete is more expensive than conventional concrete, revenue can be generated through waste disposal fees and carbon credit sales, with some players already reporting to achieve price parity. In the future, stronger regulatory support (for example, increased carbon pricing) will accelerate uptake further, with IDTechEx forecasting over 170 million tonnes of captured CO2 will be utilized in building materials by 2044. With carbon capture solutions for cement kilns continuing to develop, CO2 could be sourced from cement production, creating a circular solution.
