Additional Info

Secure Chip is designed to reduce the amount of post sweeping required by securing the dressing aggregate in the mosaic structure minimising the risk of damaged windscreens from chippings dislodged by passing vehicles. Application of Colas Ltd Secure Chip also gives a pleasing aesthetic and long lasting black colour resembling an asphalt surface.

The low application rate of Secure Chip results in the rapid breaking of the emulsion meaning that sites can be opened to traffic quickly minimising any disruption to local residents.
