The road barrier stabiliser is a smarter, cleaner alternative to sandbags for securing plastic road barriers in live traffic zones. Each 15kg unit delivers consistent ballast to meet Class B wind load compliance (17.6 m/s), ensuring stability without the mess of loose fill. Its interlocking design allows continuous rows and firm anchoring, while the central twist-lock cavity doubles as a delineator base for traffic cylinders. Made from 100% recycled PVC, these stabilisers are stackable, easy to handle and customisable with branding and colour options, which reduces site waste and improves efficiency across roadworks, events and urban projects.
