What Colas does

Colas SA is a France-headquartered, global transportation infrastructure group that designs, builds, and maintains road, railway, port, airport, and industrial logistics infrastructure for public and private clients. The company was founded in 1929 to commercialize the Cold Asphalt bitumen emulsion patent and has grown into a fully integrated operator spanning the infrastructure lifecycle: upstream bitumen sourcing and storage (70 terminals, 14 ships, 200 emulsion plants), materials production (3,500 production units, 500+ quarries, 180 ready-mix concrete plants, 90 million tonnes of aggregates in 2024), construction works (60,000 projects per year across 2,000 work establishments in 50 countries), and downstream maintenance and recycling services (750 recycling installations, 11.2 million tonnes of materials recycled annually).

The company monetizes through a mix of one-time construction contracts (project-specific pricing negotiated with government and private infrastructure operators), materials sales to third parties (70% of materials volumes sold externally, serving construction firms and artisans), subscription-style multi-year maintenance and asset management contracts, transaction-fee recycling and waste valorization services (Ecotri and Valormat platforms), and bitumen distribution through an integrated network of terminals, ships, barges, and rail. Proprietary technology developed through the CORE Center R&D hub underpins the offering, including WATTWAY solar road pavement (33 deployments in Japan), Vegecol plant-based binders, Vegeroad bio-based asphalt, Recycol cold in-place pavement recycling, Optibase high-performance bituminous structures, Flowell interactive luminous road markings, and the Infracare AI-based predictive road maintenance service.

Customers are organized horizontally across government and public authorities (municipalities, regional and national agencies), private infrastructure operators (airports, ports, toll roads, industrial sites), railway operators and authorities (Network Rail alliance, tramway and metro systems), B2B construction companies and artisans (materials supply), and individual consumers (Colas & Vous in France). Since December 2023, Colas has been a wholly-owned subsidiary of Bouygues SA following a squeeze-out and delisting from Euronext Paris, and is being consolidated into a newly unified Construction Division alongside Bouygues Construction and Bouygues Immobilier. The company employs approximately 62,000 people globally and generates around €16-18 billion in annual revenue.
