About Colas Suisse

Colas Suisse Holding is the parent company of a group of fifteen companies in French-speaking Switzerland. Our subsidiaries offer a complete range of services in the field of construction. The road has been at the heart of our activities for over 90 years. We build road infrastructure, urban or leisure developments thanks to the skills of our 650 employees. Our industries produce road products such as hard aggregates for asphalt paving, railway ballast, concrete materials, and foundation and embankment gravel. Colas Suisse was created in 1927 with the aim of exploiting a patent for bitumen emulsification (Cold Asphalt) which allows it to be applied cold. In 1929, Colas Suisse joined the Colas International group, the world leader in roads, whose special techniques and processes it applies and develops.
