World first: H-UKR 0% clinker cement obtains Technical Assessment (ATec) for wind turbine foundations
Hoffmann Green today announces that it has obtained a Technical Assessment (ATec) validating the use of its H-UKR decarbonized cement for wind turbine foundations. This unprecedented recognition, a world first for a 0% clinker cement, certifies that the H-UKR solution meets the highest standards of sustainability, safety, and performance for particularly rigorous applications such as wind power.
A strategic step towards new markets
This certification marks another key milestone for Hoffmann Green, enabling it to further accelerate its growth in the renewable energy market from 2026 and beyond. Obtaining this ATec certification paves the way for new commercial opportunities in this sector, strengthening its insurability with project owners and construction professionals.
Wind power is a high-potential market where each foundation pour requires 600 to 800 m³ of concrete. This validation is fully in line with Hoffmann Green’s diversification strategy, particularly towards large-scale projects in the renewable energy sector.
Key technical and regulatory recognition
This Technical Assessment, issued by the CCFAT (Commission in Charge of Formulating Technical Assessments) with technical support from the CSTB, is the result of 18 months of work by Hoffmann Green’s Evaluation and Quality Department. More complex than a building foundation, a wind turbine foundation must withstand concrete damage (fatigue) caused by continuous exposure to wind and vibrations throughout the wind turbine’s lifetime. H-UKR cement has been tested and proven to withstand more than 1 million compressions without any loss of mechanical performance.
This validation confirms that Hoffmann Green has achieved its technical objectives: to offer a 0% clinker-free, decarbonized cement without compromising on performance or reliability. It reinforces the Company’s technical and regulatory lead in the decarbonized cement market, meeting the highest technical requirements.
