Colas Ltd, the company
In 1925 two English companies, Cold Mix Manufacturing Limited and Asphalt Cold Mix Limited formed a new company, Colas Products Limited to supply the bitumen emulsions for use on roads. Between the years of 1934 and 1980 the company went through many changes and by 1980 consisted of two main divisions, the roads division and the building products division. In 1986 the organisation Prismo was acquired and in 1987 changed its name to Colas Holdings. The name Colas Ltd was first seen in 1992 when Colas Holdings was reorganised and the bitumen road related surface dressing activities and Prismo were transferred to a new subsidiary Colas Ltd. Colas Ltd, became a subsidiary of the international Colas Group in 1985, which is headed by Colas SA in France.
