Hoffmann Green Obtains New CSTB Assessment to Decarbonize Single-Family Home Construction With Groupe Trecobat and Fimurex Planchers

Regulatory News:

Hoffmann Green Cement Technologies (ISIN: FR0013451044, Ticker: ALHGR) (“Hoffmann Green Cement” or the “Company”), an industrial player committed to the decarbonation of the construction sector that designs and markets innovative clinker-free cements, announces that it has obtained a new Appréciation Technique d'Expérimentation (ATEx) representing a significant step towards the decarbonization of single-family home construction, in partnership with the Trecobat Group and Fimurex Planchers, a subsidiary of the Fimurex Group, key players in the sector.

Identified by the number 3380_V1, this ATEx certifies the reliability of H-UKR cement-based concrete for compression tables in shored floors over crawl spaces in single-family homes. Issued by the Centre Scientifique et Technique du Bâtiment (CSTB), a leading public institution in the fields of building quality, durability and safety, this assessment enables Hoffmann Green to expand the field of application of its decarbonized cement and accelerate its distribution in the construction sector. It also confirms the company's technical advance in low-carbon cements.

This new assessment supports a technical collaboration between Hoffmann Green's H-UKR decarbonized cement and the prefabricated floor system from Fimurex Planchers, a specialist in the design of reinforced concrete elements for single-family homes. This synergy enables, among other features, the integration of a decarbonized floor system into the Trecobat Green range of timber-frame homes, reinforcing the partnership established in January 2024 between Hoffmann Green and Trecobat, France's 4th largest builder of single-family homes. Thanks to the combination of the three partners' cutting-edge technologies, the 2031 objectives of the RE2020 environmental regulation are already being met today, underlining their commitment to the ecological transition and to reducing the carbon footprint of building.

Julien Blanchard and David Hoffmann, co-founders of Hoffmann Green Cement Technologies, said: “We are delighted to have obtained this new assessment, which confirms the relevance of our decarbonized cement in new applications in the construction sector. It reinforces our partnership with Trecobat, which aims to decarbonize single-family home construction and promote the distribution of Hoffmann 0% clinker cements throughout the sector.”

Alban BOYE, Chairman and CEO of Trecobat Group, added: “This partnership with Hoffmann Green enables us to offer our customers environmentally- responsible homes. Together, we're paving the way for innovative single-family housing solutions that already meet the 2031 thresholds of the RE2020 environmental regulations, and shaping the future of sustainable construction in the Grand Ouest region.”

Pascal BARBE, Chairman and CEO of Fimurex Group, concludes: “We are pleased to see that our reinforced concrete floor technology is contributing to decarbonization in single-family home construction, by combining it with Hoffmann Green's 0% clinker cements. This combination guarantees a high level of quality while preserving the usual processing of our floors. We look forward to seeing this process, the result of two key technologies, deployed in Trecobat Green single-family homes.”
