About us

Société Routière Colas was founded on a cold asphalt-based bitumen patent in France, 1929. A world leader in transport infrastructure works – including roads, railways and air transport –, urban developments and environmental investments, the Colas Group is currently present in 50 countries on five continents, undertaking some 100,000 projects every year with a team over 60,000 strong. Individual subsidiaries of the parent company have strong regional ties, and retain their original roots – however, they share the same values from Cambodia to Alaska: competitiveness, innovative and responsible development, flawless quality, safety and close cooperation.


The Hungarian Colas Group has been playing an active role in the country’s construction investments since 1991. Having been managed by Hungarian executives from the beginning, the holding company has become a key figure in the development of the Hungarian road network. In recent decades, Colas has built over 100 kilometres of high-speed roads in Hungary. In addition to road and motorway construction jobs, the company also plays a leading role when it comes to highly sensitive projects requiring strict organisation such as special engineering structures, urban rehabilitation and utility construction. The 11 quarries operated by the Group are located in North-eastern Hungary, between the Danube and the Zemplén Mountains. With an eye on responsible development, the Colas subsidiary marketing nearly 2 million tonnes of crushed stone is also engaged in the recycling of demolition waste.
