The Bison 800 Barrier is a water filled road barrier at 800mm height, positioned between the low-level and heavy-duty ranges in the Altrad Generation bison barrier line. Chapter 8 compliant reflective strips are fitted as standard, meeting the visibility requirements for Temporary Traffic Management on public roads without additional specification or procurement steps. The Bison 800 is the practical choice when a project demands higher visibility than a low-level barrier provides, but the budget does not extend to a full 1m heavy-duty barrier.
The pin locking system allows a 90-degree angle between barriers, enabling flexible configurations that adapt to site constraints, urban footprints, and non-linear perimeter runs. The fully stackable and anti-slide design reduces storage footprint and keeps transport loads stable, which is important on sites managing high barrier volumes across multiple work areas.
Compatible with Solid Hoard Panels and mesh toppings, the Bison 800 extends to 2.0m for increased security. Optional Pedestrian And Vehicle Gates are available for access management within the barrier line, making the Bison 800 a complete mid-range water filled barrier hire option for construction sites, roadworks, and urban event management.

Frequently Asked Questions
Q. What is the difference between the Bison 800 Barrier and the Bison Barrier?
A. The Bison 800 Barrier stands at 800mm height. The Bison Barrier is 1m (1000mm) tall. Both are water filled road barriers and both are Chapter 8 compliant with reflective strips fitted as standard. The Bison 800 is suited to projects where a higher visibility profile than a low-level barrier is needed, but the full height of the 1m Bison is not required or not within budget. When height and maximum stability are the priority, the Bison Barrier is the stronger specification. For cost-sensitive projects with a high visibility requirement, the Bison 800 provides a compliant mid-range alternative.
Q. Can the Bison 800 be extended in height?
A. Yes. Adding a mesh topping extends the Bison 800 Barrier to 2.0m overall height for anti-climb security and increased separation. Solid hoard panels are also compatible. For access management, optional pedestrian and vehicle gates are available within the barrier system. This range of topping and gate options means the Bison 800 works across a variety of site configurations where the base barrier height needs to be supplemented for specific security or pedestrian segregation requirements.
Q. What does Chapter 8 compliant mean and how does the Bison 800 meet it?
A. Chapter 8 of the Traffic Signs Manual sets out the standards for temporary traffic management on public roads, including requirements for the visibility and reflectivity of barriers. The Bison 800 meets Chapter 8 requirements through reflective strips fitted to each barrier as standard. For site managers and procurement leads specifying water filled barrier hire for street works, the fitted reflective strips remove the need to source and attach separate reflective components. The anti-slide stacking feature and 90-degree pin locking system support safe transport, storage, and flexible layout configuration across the project.
