The Road Rock is a multifunctional base and the first product of its kind that will allow a temporary pedestrian barrier to pass Class B Wind Speeds (17.6m/s) by providing the precise weight needed each time, using two Road Rocks. When the barriers are in a boxed formation, only a single Road Rock is needed per barrier to pass Class B. Use of the Road Rock removes the need for sandbag filled ballasts, therefore resulting in a cleaner area of works. The Road Rock has a hook and tail connection similar to that seen on the Road Runner, this makes it possible to create a continuous run and implement the base as a delineator. A cavity within the centre of the Road Rock allows a twist-to-lock cylinder to be attached. At 15kg in weight, the Road Rock is manufactured from 100% recycled PVC, which is also 100% recyclable.
