The Bison Barrier is a 1m water filled road barrier, the standard Chapter 8 barrier for road works, and the only water-filled traffic road separator with Chapter 8 compliant reflective strips fitted as standard. At 400kg when water-filled across its 2m length, the Bison Barrier provides substantial stability for roadworks, Construction Site Traffic Management, and event perimeter control. MIRA wind speed tested to 75mph when water-filled, it is a reliable specification for exposed sites and high-traffic environments where a verified wind resistance rating is required.
The pin locking system allows barriers to be angled up to 90 degrees for tailored layouts across corners, urban footprints, and site-specific configurations. The fully stackable design with built-in anti-slide features makes the Bison Barrier safe and space-efficient to transport and store, with a high barrier-to-pallet ratio that reduces logistics costs on large-volume deployments.
Mesh toppings, hoard toppings, hoarding panels, and pedestrian and vehicle gates are all available as accessories. For projects requiring a complete perimeter system, the Bison Barrier and its accessories work together to manage access, increase height, and maintain Chapter 8 compliance across the full barrier run.

Frequently Asked Questions
Q. How heavy is the Bison Barrier when water filled?
A. The Bison Barrier weighs 400kg when water-filled, from an empty weight of 35kg. Each unit is 2m long and 1m high. The filled weight provides strong stability across construction sites, roadworks, and events, and the MIRA wind speed rating of 75mph when filled gives a verified performance figure for traffic management planning on exposed sites. The 90-degree pin locking system allows angled configurations while maintaining barrier stability at the connection points.
Q. Is the Bison Barrier Chapter 8 compliant?
A. Yes. The Bison Barrier is Chapter 8 compliant and is the only water-filled traffic road separator with Chapter 8 reflective strips fitted as standard. Most comparable water filled road barriers require separate reflective components to achieve Chapter 8 compliance on street works. The Bison Barrier delivers compliance as part of the standard product specification, which simplifies procurement and reduces the risk of non-compliance on site.
Q. What accessories are available for the Bison Barrier?
A. The Bison Barrier is compatible with Mesh Toppings (2kg), Hoard Toppings (10kg), hoarding panels, pedestrian gates, and vehicle gates. Mesh and hoard toppings increase the barrier height for anti-climb and site separation applications. Pedestrian and vehicle gates create managed access points within the barrier line for construction site entry management, event crowd flow, and roadworks site access. This accessory range makes the Bison Barrier the foundation of a complete temporary traffic management perimeter system.
