Hermet Beton

What Hermet Beton does

Hermet Beton is a French manufacturer of concrete products for the building construction, public works, and outdoor landscaping markets, founded in 1924 and headquartered in Marssac-sur-Tarn (registered office at Labastide-de-Lévis), France. The company operates four production sites across the Occitanie region (Tarn, Haute-Garonne, and Tarn-et-Garonne departments) and sells under an SAS corporate structure with a share capital of €514,800. Since October 9, 2023 it has been a subsidiary of Groupe LIBAUD SA, which provides group-level strategic and capital backing.

The product portfolio spans five functional categories: concrete blocks (including Planibloc and Thermbloc), formwork systems (notably the proprietary ISORIVE insulating formwork, which carries a six-year Avis Technique from CSTB valid through 2030), paving and outdoor landscaping (MANULINTEAU), public works products (MANUCOFFRE, MANUBAIE), and engineered formulations including XF4 exposure-class concretes. Manufacturing is supported by NF and CE product certifications, FDES/INIES environmental declarations, and technical partnerships with CERIB, CSTB, LAFARGE (low-carbon cement supply), and ECOMINERO (recycled aggregates). The low-carbon block range, co-developed with LAFARGE, reports a 32% reduction in carbon emissions versus standard formulations.

The business model is direct B2B sales of manufactured concrete products to contractors, public works operators, municipalities, distributors, and end-clients across transport, civil engineering, healthcare, and retail projects in southern France. Revenue is generated through unit-volume sales of certified, specification-grade concrete products; pricing is project-based and tied to volume, mix, and delivery logistics. Customer logos include GROUPE MAUREL TRANSPORTS, TRANSPORT ANDRIEU, GROUPE GAGNERAUD & LAMBERTON, Groupe ROY-BAPTISTAN, NGE-BTP, CMCTP 87, TSM, DEMUSSI, the Canal de Saint-Martory, the Hôpital de Carcassonne, and Centre Leclerc Le Sequestre (Montpellier), indicating a diversified regional customer base with low dependence on any single account.
