Our action
Connecting communities and fostering exchanges for the world of today and tomorrow.
Transport is about more than just getting from point A to point B. Transport infrastructure is the bond that connects people and communities.

Since it was founded, Colas has been building and maintaining transport infrastructure, fostering human connections, cultural exchanges and economic activity in communities around the world.

We are gradually positioning ourselves as an integrator of global sustainable mobility solutions, in anticipation of augmented-reality roads and sustainable cities.

Our history
Opening the way for over 90 years
Colas is a subsidiary of the Bouygues Group. Bouygues became the company's main shareholder in 1986, and now holds 100% of Colas since December 2023.
The origins of Colas date back to 1922, when Cold Spray bitumen emulsion was patented in London. The innovation was named Cold Asphalt in 1924. The name Colas was derived from the abbreviated form of Cold Asphalt.
Colas was created to rise to a new challenge: exploiting the bitumen emulsion patent, which revolutionized road techniques.
Over the decades, Colas has widened its business ranges, branching out into activities relating to its core road business, mainly construction materials, and, at the beginning of the 2000s, railways. Present since the 1930s in Europe and Africa and then in North America in the 1960s, Colas has multiplied its bases on all five continents. Driven by this same original pioneering spirit, the Group has developed innovative products, processes and solutions. Today, Colas continues to innovate to meet ever-growing, ever-changing mobility needs responsibly and sustainably.
