Specialist Processes and Surface Treatments

Innovative, specialist road repair and maintenance

Colas has over 50 years experience and expertise in repairing, protecting and extending the usable lifespan of infrastructure roads, footways and other surfaces. When roads surfaces develop ruts and deformations, have water problems and where skid resistance starts to fall, our affordable, innovative and unique specialist surface treatment solutions will help maintain safety standards and extend the life of your roads by up to 10 years. 

Whether you have a need to do small road surface repairs or your road requires a deeper resurfacing, Colas innovative surface treatment solutions are flexible and can be prepared to meet your requirements. We supply options to repair and upgrade the surface, without necessarily needing to engage in a far more costly and time-consuming resurfacing programme.
