Durmeyer

What Durmeyer does

Durmeyer SAS is a privately held, family-owned French specialty foundation contractor headquartered in Mittersheim, Moselle, operating from the strategic Metz-Nancy-Strasbourg triangle. Founded in 1725 and now in its ninth generation under proprietor Mathieu Durmeyer, the company has specialized in deep foundations and river works since 1935, making it one of the oldest continuously operating entities in the French fondations spéciales sector. Its technical scope spans bored piles (tubular temporary/permanent, hollow auger, double-rotation hollow auger, screw-cast, vibro-driven/driven steel), rigid inclusions, injected cement/silicate plugs, and steel sheet piling for cofferdams, quays, bank protection, and lock modernization, including work executed from water via modular floating pontoons.

The company executes projects either directly for project owners or as a subcontractor to general contractors, serving French public infrastructure clients (SNCF Réseau, Voies Navigables de France, ENEDIS, Eurométropoles of Strasbourg and Metz, Métropole du Grand Nancy, Région Grand Est, departmental councils) and major primes (Bouygues, Eiffage, Spie Batignolles, VINCI, Demathieu & Bard). Revenue is generated through custom project-based B2B contracts with no standardized pricing, billed per project specifications across pile diameter, depth, soil conditions, and complexity, with multi-year contract cadences. The firm differentiates through in-house execution studies, a recently renewed heavy equipment fleet (BAUER BG20H+/BG36/BG40, ABI 12-16, crawler cranes up to 80t, vibrodrivers, modular pontoons), and collaborative R&D with CEREMA and ARCELOR-MITTAL on novel techniques such as double-rotation hollow auger and jet-assisted sheet pile driving. Operating geographies cover all of France plus Germany, Belgium, and Luxembourg, though activity is concentrated in Grand Est and bordering regions.
