Colas is a world leader in transport infrastructure construction and maintenance, using its activities and innovations to promote solutions for responsible mobility.
A world leader
Colas operates in over 50 countries around the world through a decentralised network of 800 profit centres and 2,000 units producing and recycling construction materials such as aggregates, asphalt mixes, binders and bitumen.
Its 58,000 employees, 42% of them outside France, share a common corporate culture and values based on entrepreneurship, creativity and responsibility.
Colas completes more than 85,000 projects a year, often small in size but also more complex in nature (PPPs, concessions and long-term contracts). Colas generated sales of €13.2 billion in 2018, of which 51% on international markets (25% in North America, 18% in Europe excluding France and 8% in the rest of the world).
Three main business activities
- Roads, Colas’ core business, spans the construction and maintenance of roads and motorways, airport runways, ports, industrial logistics and commercial hubs, urban roads and amenities, external works, reserved-lane public transport (bus lanes and tramways), leisure facilities and environmental amenities. The roads division includes Colas’ civil engineering and building businesses.
- Construction materials: Colas has a significant production and recycling of construction materials activity (aggregates, emulsions, asphalt mixes, ready-mix concrete, bitumen) as well as a bitumen distribution activity.
- The Railways activity comprises the design and engineering of complex, large-scale projects and the construction, renewal and maintenance of rail networks (conventional and high-speed rail lines, trams and metro systems).
Colas is also present in Waterproofing (waterproofing membranes, the roofing and cladding of buildings), Road safety and signalling (road safety equipment), and Networks (laying and maintenance of pipes and pipelines).
A ground-breaking and responsible player
Colas has been a constant innovator since its creation in 1929. Its research and development policy focuses on sustainable development in areas such as recycling, energy-saving cold techniques, eco-designed products and vehicle detection sensors. In 2015, Colas launched a major ground-breaking innovation: Wattway, a photovoltaic road surface. This technology is currently being trialled on around thirty different pilot sites around the world.
With Wattway, roads are no longer just a way of getting from A to B but also become local sources of clean and renewable energy. In phase with the global objective of energy transition, this revolutionary technology paves the way for the future through communicating, positive-energy roads.
In 2017, Colas launched a new dynamic road-marking solution called Flowell. This innovative technology will help resolve local mobility challenges by organising the shared space of roads and city streets thanks to a system based on the dynamic control of light-emitting signalling. For example, parking spaces reserved in the daytime for deliveries can be turned into car parking spaces at night. The solution can also be used to secure pedestrian crossings by enhancing their visibility, and that of pedestrians, with light-emitting markings. Instead of just places of transit, roads become places for sharing.
In addition to these new features for infrastructure (Smart Road), Colas also offers innovative mobility solutions that can predict when infrastructure requires upkeep and maintenance, by harvesting and analysing data (Road as a service), and that can provide services to users (Smart Mobility) such as smart and pooled car parking or the optimisation of transport flows around urban worksites.
