A water-filled barrier is a plastic road safety barrier that is easy to carry while empty and gains weight once filled with water after positioning. It is the practical alternative to concrete barriers for temporary traffic management.
Why Choose a Water Barrier?
- Light and portable: one person can carry it empty; no crane or machinery needed.
- Fast installation: interlocking ends form long runs within minutes.
- Impact absorbing: the water mass absorbs crash energy; damage to vehicle and driver is far lower than with concrete.
- High visibility: red and white bodies with reflective options are noticeable day and night.
Where It Is Used
Lane separation at road and infrastructure works, junction rearrangements, event and marathon routes, site entrance control and temporary pedestrian corridors are the most common applications. In flood-prone areas they are also used to direct water.
Installation and Usage Tips
Connect the barriers at their locking points and finish runs with proper end elements. After filling through the top cap, check the drain plug. In winter, leave some capacity unfilled or add antifreeze to protect against freezing.
