History
Colas, the name
In the 1920s, patents were filed by two British chemists, Hugh Alan Mackay and George Samuel Hay, for improved methods of preparing a bitumen emulsion. In 1924, exclusive rights to patents in France were obtained by Alexandre Giros for use by the Société Générale d'Enterprises (SGE). The product was given the name Colas in 1924, deriving from the terms 'cold' and 'asphalt'.
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.
