The HERMEQ Road Barrier Stabiliser – known as the Road Rock – offers a smarter way to ensure wind compliance across live roadworks and traffic management zones. This 15kg stabilising unit eliminates the mess and inconsistency of sandbags, while delivering the exact ballast required to support plastic road barriers under Class B wind load standards.
Its interlocking design enables continuous rows and stable anchoring of individual or grouped barriers. A central twist-lock cavity also allows it to be used as a delineator base with standard traffic cylinders. Built from recycled PVC and designed for stacking, this stabiliser reduces onsite waste, improves handling, and supports high-efficiency deployments.
- Consistent load per unit – Each stabiliser weighs 15kg to meet Class B requirements (17.6 m/s).
- No sandbag handling required – Cleaner, faster site setup and takedown.
- 100% recycled material – Environmentally sound and fully recyclable base unit.
- Twist-lock cylinder compatible – Converts into delineator for zoning or footpath redirection.
- Stackable and branded – Customisable with company embossing and colour options.
Ideal for use across traffic barrier setups, signage bases, and water-filled systems, this traffic barrier stabiliser supports operations in road construction, event management, and urban street works. HERMEQ stock a wide range of plastic road barriers, traffic signs, and barrier units for comprehensive traffic safety deployments.

Wind Load Compliance
Each unit contributes 15kg of precise ballast, making it suitable for use in live carriageway works and high wind conditions. It allows Chapter 8 barriers to pass Class B tests without ad hoc weights.
Efficient Site Setup
The interlocking shape means the stabiliser links into barrier formations or functions as a standalone support. The stackable design reduces logistical hassle during deployment or storage.
Dual-Purpose Design
The twist-lock cavity allows the unit to function as a base for traffic cylinders, adding vertical visual alerts to your layout without separate equipment. Perfect for flexible site marking and crowd control areas.
