Colas was created with the aim of exploiting a patent for bitumen (Cold Asphalt) which allows it to be applied cold. Since 1929, Colas Suisse has been part of the Colas International group, the world leader in roads, whose special techniques and processes it applies and develops.

For over 80 years, roads have been at the heart of the activities of Colas Suisse, which builds and realizes road infrastructures, urban or leisure developments thanks to the skills of its employees.

Our industries produce and manufacture road products such as hard aggregates for bituminous pavements, railroad ballast, concrete materials, foundation and riprap gravel.
