water barrier

Water-filled road safety barriers are energy-absorbing, interlocking plastic barricades designed to cushion collisions, separate lanes, and manage traffic flow in work zones and construction areas. Made primarily from high-density polyethylene (HDPE) or linear low-density polyethylene (LLDPE), they are highly portable when empty and provide exceptional stability once filled with water or sand.

Key Technical Specifications & Sizes

Water barriers vary depending on the traffic density, vehicle speed, and space availability of the application zone:

Mini/Pedestrian Barriers (1000mm length): These typically hold 20 to 30 litres of water, feature heights around 760mm to 855mm, and are best suited for parking facilities, pedestrian zones, or low-speed urban streets.

• Standard Mid-Size Barriers (1300mm to 1700mm length): Commonly holding 50 to 60 litres of ballast, with a height of roughly 1000mm, these provide solid visual guidance for city road diversions and infrastructure construction projects.
• Highway & High-Capacity Barriers (2000mm+ length): Designed for high-speed zones, these hold 100 litres or more of water ballast, measures over 1000mm in height, and feature a robust footprint to maximize kinetic energy absorption.
