What denni legoll entreprise de transports et de travaux publics does

Denni Legoll Entreprise de Transports et de Travaux Publics is a privately held French small-to-medium enterprise headquartered in Griesheim-près-Molsheim, Alsace, providing integrated public works services across six core disciplines: earthworks (terrassement), road construction (voirie), sanitation and drainage (assainissement), drinking water networks (eau potable), soil decontamination (dépollution), and inert waste recycling (recyclage). Founded in 1946 by Henri Denni and subsequently built by the Legoll family, the company was reconstituted in December 2012 when its assets were sold to Michel Heintz, owner of Adam TP Bouxwiller and Adam Ostwald. It is currently led by Directors Jean-Eric Legoll and Jean-Luc Regnery and employs approximately 90 staff.

The company's service portfolio is underpinned by an in-house independent analysis laboratory for soil and material characterization, a dedicated on-site inert waste recycling platform, and a partnership with Ceterra for mobile crushing/screening and in-situ soil depollution techniques. Membership in the Zénith union of companies provides pooled equipment and combined expertise that approximates the delivery capacity of a larger national group while preserving SME-level responsiveness. Customers span municipal and governmental buyers (Eurométropole, communes including Rosenwiller, Lampertheim, Obernai) and industrial enterprises (Huron, Schmidt Groupe, ROMA, Octapharma, Soprema, Intercarat/GEMÜ), served primarily across the Bas-Rhin/Alsace and broader Grand Est regions.

Revenue is generated through project-based, quote-driven contracts won via public procurement tenders and private construction tenders. Pricing is not publicly disclosed; contracts are negotiated individually, typical of the public works industry, with multi-year engagement on larger industrial platform and infrastructure projects. The GTM motion is direct and sales-led, supplemented by cross-referrals through the Zénith union network. There are no disclosed funding rounds, and ownership remains in private hands under the Heintz umbrella alongside Adam TP.
