Colas Solutions™ and the many companies within the Colas Group come from a long history of providing our neighbors the benefits of innovative, long-lasting construction products and preventive maintenance systems. In the early 1920s, two British chemists, Hugh Alan Mackay and George Samuel Hay, devised the first bitumen emulsion. The ensuing “Cold Asphalt” patent, from which the “Colas” name is derived, was first licensed in 1924. Today, that innovation continues and has led to one of the world’s leading Global construction companies and the world’s largest asphalt emulsion producer. Colas Solutions™ continues in the Colas Group tradition by focusing on strong research and development, continuous improvement of industry products and systems, and delivery of innovative, responsible solutions for building, maintaining, and preserving today’s infrastructure investments through our various companies and customers.
