What is a Water-Filled Road Barrier?
A water-filled road barrier, also known as a security barrier, is a safety product used to block construction sites, facility entrances/exits, and road maintenance areas from pedestrian or vehicle traffic. Made from UV-resistant polyethylene, these barriers are hollow, making them lightweight, portable, and easy to stack for storage.
When filled with water or sand, they provide strong protection, comparable to concrete barriers. Their interlocking design allows for continuous barrier formation or, they can be used individually. Some models can also be stacked vertically to increase height.
Where Are Water-Filled Road Barriers Used?
- Construction and excavation sites
- Facility entrances and exits
- Event areas (fairs, shows, concerts)
- Traffic lane separation
- Crowd control at public gatherings
The adjustable weight feature allows users to customize the barrier’s stability by varying the water or sand inside. These barriers are typically produced in high-visibility colours such as red and white, making them more noticeable than steel or concrete barriers.
Features of Water-Filled Road Barriers
- Capacity: Holds 100 - 250 litres of water/sand, depending on size.
- Customizable weight: Fill with water or sand to adjust stability.
- Interlockable design: Can be connected to longer barriers or stacked for height increase.
- Highly visible: Bright colours ensure better visibility than concrete or metal barriers.
- Weather-resistant: Made from UV-resistant polyethylene to withstand outdoor conditions.
How to Install Water-Filled Road Barriers?
- Position the barriers individually or interlock them to create a continuous structure.
- Open the top filling caps and add water or sand as needed.
- Secure the caps to prevent leakage.
- For temporary use, empty the barriers before storage to make them easy to transport.
