GB2 2m Road Safety Water-Filled Barrier

Product Overview:
The GB2 2m Road Safety Water-Filled Barrier is a heavy-duty, interlocking separator for temporary traffic management, pedestrian segregation and site delineation. Manufactured from UV-stabilised polyethylene, each unit provides two metres of working coverage and remains manageable at approximately 32kg when empty. Once filled to the marked level, its weight increases to around 350kg, creating a stable boundary for roadworks, construction sites, public events, depots and infrastructure projects.

The high-visibility red or white body clearly identifies restricted routes and working areas, while the hook-and-eye connection creates continuous runs and turns through angles of up to 35 degrees. Filled GB2 barriers have been wind tested to 78mph in the manufacturer’s standard test arrangement, supporting use on exposed temporary sites. The stackable design reduces transport and storage space, while compatible mesh, hoarding and gate options provide additional height or controlled access where required. The GB2 is intended for traffic and pedestrian delineation rather than certified vehicle restraint.

Frequently Asked Questions:
Q. What are the dimensions and weight of the GB2 barrier?
A. Each unit provides a 2000mm working length and measures approximately 900mm high by 500mm deep. It weighs around 32kg empty and approximately 350kg when filled to its 318-litre fill level.

Q. What wind speed has the GB2 barrier withstood?
A. Two connected GB2 barriers, filled to the specified level, have been wind tested to 78mph. Site exposure, layout and any fitted panels must still be considered before installation.

Q. Can GB2 barriers form corners or curved layouts?
A. Yes. The hook-and-eye connection allows adjoining units to turn through angles of up to 35 degrees, enabling gradual corners and shaped barrier runs.

Q. Are mesh panels, hoarding panels and gates included?
A. No. The barrier is supplied as the base unit. Compatible mesh panels, solid hoarding panels and pedestrian or vehicle gates are available separately.

Q. Is the GB2 a certified crash or vehicle-restraint barrier?
A. No. The GB2 is intended for traffic delineation, pedestrian segregation and temporary site safety. It should not replace a certified vehicle-restraint system unless specifically approved within the project design.
