Water Filled Barriers

Hire or Buy
Our water filled barriers are ideally designed for construction sites and roadworks. Water filled barriers are high visibility, durable, plastic safety barriers which are designed to protect staff and the general public. Water-filled barriers provide a robust and reliable safety system that is quick and easy to assemble. Our barriers come in a range of sizes and can be used in conjunction with other items such as pedestrian gates, vehicles gates, hoarding and fencing. The RB22 system also features a crash test certification (according to British Standards).

One of the reasons that water filled barriers are so popular is their portability.  When empty, these barriers are comparatively light, and can be easily stacked, transported and assembled. Made from UV stabilised polythene, they offer a safe, robust and reliable solution for a multitude of projects.

The height of the barriers ranges between 600mm and 1000 mm but they also interlock with fence panels and hoarding to increase the overall height. All our water filled barriers (excluding the RB1000 barrier) are available with one or more fence attachments which slot into the top of the barrier. Many of our barriers also allow for the addition of either vehicle or pedestrian gates to provide for ease of access.

The option to emboss the barrier with your corporate logo is also available on some of the products in the range.


Whilst the water filled barriers come in different sizes, shapes and weights they all link together in a very simple way. The relatively light weight of the barriers when empty means that positioning them in place to interlock is very straight forward. Most models can be installed quickly by a 2-person team (when empty) and are completely reusable and extremely durable. The barriers can also be positioned in a straight line or curve (as required) and certain models also have corner units to help create 90 degree angles. 

Slots at the bottom of most of our water-filled barriers means that they can be moved with forklifts and machinery (when filled). When the barriers are empty, they can be moved by hand. 

The larger models also feature a drainage plug which can be released for ease of dismantling. We have created installation guides and videos for many of our products, please see below for a list of the some of guides available, or contact a member of the sales team for more information.

Types of barrier

We offer water filled road barriers, crash-tested barriers, barriers with fence panels, RB22 barriers for racetrack safety and anti-trip barriers. Our barriers are available in a range of colours, and can come with anti-tamper plugs to reduce the risk of vandalism and theft.


Our barriers can be filled with water and sand and are designed for all weather conditions. The weight of the barriers range from 28kg (EVO road barrier) to 600kg (RB22 crash barrier) when filled.


The barriers can be used to direct pedestrians and security at outdoor events. The crash-tested models (such as the RB22) offer ideal perimeter protection for highway and construction works.  The ability to add mesh fences, gates or hoarding panels means that the barriers are a very adaptable solution for most applications. Adding fence panels can also improve protection from falling debris or projectiles (e.g. at race tracks). Anti climb fence panels or construction hoarding increases overall security and safety of a site, preventing people from being able to view and gain access to unwanted areas. We even offer models which are specifically designed for race tracks.
