Colas have been laying surface dressing for almost 100 years and are nationally and internationally recognised as a market leader and industry innovator in this sector.  The treatment is regarded as one of the most cost effective means of maintaining and restoring road surface condition.  Sealing of the road surface by specialist binder and the application of aggregate "chippings" provide a durable skid resistant surface at relatively low cost and Colas offer a full contracting service or alternatively, the supply and application of binder to supplement other operations

Full Contracting Service

Colas have the resources and expertise to ensure that all types of work are undertaken safely, reliably and speedily by our highly skilled workforce and modern computer controlled equipment.
