Product Details
Evo Stackable Water Filled Barrier
The Evo Barrier range covers three sizes of stackable, interlocking water filled plastic barriers for temporary access control, pedestrian demarcation and site safety. All three sizes link together at the interlocking connection points to form a gap-free, continuous barrier wall. Once linked, the run creates a solid, no-entry zone with no gaps between units. Barriers can be filled with water or sand on site to add ballast and increase stability. Empty barriers are lightweight enough for one-person assembly and deployment.
The range divides into two height profiles. The 1m and 1.5m models are both 555mm high, providing a mid-height pedestrian barrier suitable for construction site perimeters, event crowd management and public space demarcation. The 1.2m model, known in the industry as the Evo 80, stands taller at 800mm. This makes the 1.2m the stronger visual deterrent of the three, used where additional height is required for carriageway-adjacent works, higher crowd pressure environments or applications where a more prominent barrier line is needed. The length difference between the 1m and 1.5m gives buyers flexibility over perimeter coverage per unit without changing the height profile.
Manufactured from UV stabilised MDPE, all three variants are built for outdoor use with resistance to UV degradation and weathering across their working life. All sizes are fully stackable for efficient storage and transportation between sites. Red and white are the standard colour options. A custom colour is available on request: select the custom colour option at the product page and enter your required colour in the text box provided. A per-unit surcharge applies for custom colour orders.
The Evo Gator Barrier is a separate, shallower and narrower barrier unit in the same product family, suited to applications where a lower-profile separator is needed.
Key Features
- Gap-free interlocking design: All three sizes link together at the male and female connection points to create a continuous barrier wall with no gaps between units.
- Water or sand fillable: Filling adds significant ballast to each unit. Water filling gives 26.3kg (1m), 29kg (1.2m) or 30kg (1.5m) of filled weight, compared to 6.3kg, 9kg or 10kg empty.
- Two height profiles in one range: 1m and 1.5m sit at 555mm high. The 1.2m (Evo 80) sits at 800mm. Choose based on the height requirement of your application, not just the length.
- UV Stabilised MDPE: Manufactured from medium density polyethylene with UV stabilisation for outdoor use across the full working life of the product.
- Fully stackable: All three sizes stack for efficient storage and transportation. One person can assemble and deploy each unit.
- Custom colour available: Standard red and white are stocked. A custom colour can be ordered by entering your required colour in the text box on this page. A per-unit surcharge applies.
- Wind tested: Confirmed wind-tested for outdoor site use.
- Compatible accessories: The Mini Mesh Panel, Mini Mesh Reflective Panel, Post and Plank Reflective Panel and Evo Angle all work with the Evo Barrier range to extend height, improve visibility and form corners.

Size Selection Guide
The single most important decision for this product is the height, not the length. All three sizes interlock and work together, but the 1.2m model (Evo 80) stands significantly taller at 800mm compared to the 555mm height of the 1m and 1.5m models. Choose height first, then choose length based on your perimeter coverage requirement.
Choose 1m or 1.5m (555mm high) when:
The application requires a mid-height pedestrian barrier for site demarcation, event crowd management, public space separation or construction site perimeter control where full-height visual impact is not the primary requirement. The 1m is the most compact and most easily handled unit. The 1.5m covers 50% more perimeter per unit at the same height, reducing the number of connection points in a longer run.
Choose 1.2m / Evo 80 (800mm high) when:
The application requires a taller barrier for carriageway-adjacent works, higher crowd pressure environments, urban pedestrian zones or any situation where a more prominent visual deterrent and greater barrier height are needed. The Evo 80 provides 245mm more height than the 555mm models, which is a significant difference in barrier presence on a live road or in a busy public space.
Mixing sizes: All three sizes interlock with each other. A run can include multiple size variants where a height transition within the barrier line is acceptable. Confirm specific mixed-run configuration suitability before deploying at carriageway-adjacent or event crowd management applications.
Application Suitability Guide
For reference only, not legal advice. Always carry out your own site risk assessment before use.
| Application | Suitable | Recommended Size | Notes |
|---|---|---|---|
| Construction site pedestrian exclusion zones | Yes | 1m or 1.5m for general demarcation. 1.2m where a taller, more prominent barrier line is needed. | Fill with water or sand for stability on open or exposed sites. Always carry out site risk assessment before use. |
| Event crowd management and pedestrian routing | Yes | 1m or 1.5m for standard event routing. 1.2m where greater crowd deterrence is needed. | Custom colour available for branded event installs. Use Evo Angle to form corners and closed perimeters. |
| Carriageway-adjacent highway and utility works | Confirm before use | 1.2m (800mm high) where barrier height is a priority for carriageway visibility. | This is a light duty water filled barrier. It is not a crash-tested or Chapter 8 certified traffic barrier for live carriageway separation. Confirm with your traffic management plan before use in any active carriageway environment. |
| Utilities excavation and trench access control | Yes | Any size. 1m for compact excavation zones. | Confirm site safety plan requirements before use. Fill with sand for longer-term static deployments. |
| Public space and retail pedestrian zoning | Yes | 1m or 1.5m for lower-profile indoor and semi-outdoor use. | Custom colour available where branding or colour-matched deployment is needed. |
| Vehicle containment or crash barrier application | No | Not applicable | The Evo Barrier is a light duty pedestrian barrier and is not rated for vehicle containment or crash applications. A crash-tested barrier is required for those applications. |

Water Fill vs Sand Fill
Fill with water for temporary deployments where the barrier will be moved or relocated regularly. Water empties quickly through the drain plug for easy transport and repositioning.
Fill with sand for longer-term or semi-permanent installations where the barrier will remain in place for an extended period. Sand provides similar ballast to water but does not drain as quickly, making it the better choice where stability over time matters more than ease of relocation.
Frequently Asked Questions
Q: What is the difference between the 1m, 1.2m and 1.5m variants?
A: The key difference is height, not just length. The 1m and 1.5m both stand at 555mm high. The 1.2m (known as the Evo 80) stands at 800mm high, which is 245mm taller. If your application requires a more prominent barrier line, greater visual deterrence or additional height at carriageway-adjacent locations, choose the 1.2m. If standard mid-height pedestrian demarcation is sufficient, the 1m or 1.5m covers the application. The choice between 1m and 1.5m is a perimeter coverage decision: the 1.5m covers more linear metres per unit, reducing connection points in a longer run.
Q: Can all three sizes be used together in the same barrier run?
A: Yes. All three sizes interlock at the male and female connection points and can be used in combination within the same run. If you mix sizes, there will be a visible height transition between the 555mm and 800mm units. Confirm whether a height transition is acceptable for your specific application before ordering a mixed run.
Q: Should I fill with water or sand?
A: Fill with water for temporary deployments where the barrier will be moved or relocated. Water drains quickly through the drain plug, making repositioning straightforward. Fill with sand for longer-term or semi-permanent installations where the barrier will remain in place and ease of drainage is less important than sustained ballast weight.
Q: Can I order a custom colour?
A: Yes. Select the custom colour option on this page and enter your required colour in the text box provided. A per-unit surcharge is added automatically. Standard red and white are stocked for immediate dispatch. Custom colour orders will have a longer lead time. Contact our team on 0330 056 4420 to confirm lead time before placing a custom colour order.
Q: Can I add mesh panels or reflective panels on top of the barriers?
A: Yes. Each Evo Barrier unit includes purpose-made top grooves that accept mesh fence panels, mini mesh reflective panels and post and plank reflective panels. This increases the overall barrier line height and visibility. Mesh panels are sold separately. Confirm panel compatibility with your chosen barrier size variant before ordering.
Q: How do I form corners within a barrier run?
A: The Evo Angle is a corner unit that creates left and right turns within an Evo Barrier perimeter, allowing you to form a fully enclosed, gap-free no-entry zone. The Evo Angle is confirmed compatible with the 1m and 1.5m variants. Confirm compatibility with the 1.2m before ordering. The Evo Angle is sold separately.
Q: What is the difference between this product and the Evo Gator Barrier?
A: The Evo Gator Barrier is a separate, lower-profile unit in the same product family. It is shorter (500mm high), narrower (300mm wide) and lighter (4.6kg empty / 16kg filled) than any of the three Evo Barrier sizes on this page. It suits applications where a more compact separator is needed rather than a full-height barrier wall. The Evo Gator is available on its own product page.
