What Entreprise CHARIER does
Entreprise CHARIER is a privately held, family-owned French public works and civil engineering contractor founded in 1897 in Redon and headquartered in Couëron (Loire-Atlantique). Operating across the Grand Ouest of France — Bretagne, Pays de la Loire, Poitou-Charentes, with expansion into Île-de-France, Normandie, and Saint-Pierre-et-Miquelon — the company employs over 1,000 people and operates 16 quarries with aggregate production capacity up to 1,000,000 tonnes per year at the La Mariais (Donges) site alone.
The company delivers eight core service lines: quarrying and material recycling (including two écoterres for asbestos waste), road construction and urban works, green spaces and landscape, large-scale earthworks, maritime and river civil engineering, demolition and asbestos removal, ecological engineering, and water/fiber networks. It also pursues proprietary product innovations — notably Hélianthe (thermal asphalt that recovers solar energy for water heating), SOLIF (photovoltaic panels embedded in road surfaces), and Recy'casques (helmet recycling). Capital equipment investments include a Liebherr R960 high-reach demolition excavator (32 m working height) and an INTRAME FLOWMIX 220 R asphalt plant at Mauges Enrobés with 50% recycling rate.
CHARIER generates revenue primarily through competitive public procurement bids for government infrastructure contracts (roads, highways, maritime works, municipal projects) and direct negotiation with industrial clients such as Chantiers de l'Atlantique, Volvo, Lidl, LSDH, and Boralex. Secondary revenue comes from aggregates and materials sales from company quarries. Recent strategic moves include three acquisitions in 2022–2024 (CHOGNOT, FTPB, S3A/2LTP/TERREXO) totaling 70+ employees, joint ventures with SUEZ (Atlantic Terres Solutions, €10M) and OGD/ORTEC (Terrea Ouest, €1.3M), opening of capital to employees in 2024, and adoption of Entreprise à Mission legal status under fifth-generation family governance led by Emmanuelle Charier (Supervisory Board Chair) and Jean Vidal (CEO).
