Water filled barriers are the go-to solution for temporary traffic management across the UK. Lightweight when empty for easy transport, heavy and stable when filled — they're the perfect balance of portability and performance.
Why Water Filled Barriers?
- Lightweight when empty — one person can carry and position them
- Heavy and stable when filled — up to 500kg+ per barrier
- No crane or machinery needed for deployment
- Interlock together for continuous barrier runs
- Chapter 8 compliant for highways use
- Reusable hundreds of times — drain, stack, and store
Types of Water Filled Barriers
Standard Road Barriers
1m and 2m plastic barriers that interlock end-to-end. Filled with water or sand for stability. The standard choice for roadworks, lane closures, and construction site perimeters.
High-Visibility Barriers
Red, white, or orange barriers with reflective panels. Maximum visibility for high-speed road environments. Meet Chapter 8 requirements.
Anti-Gawk Screens
Tall barriers that block the view of accident scenes or works to prevent rubbernecking. Reduce secondary accidents on motorways.
Pedestrian Barriers (Water Filled)
Smaller barriers for pedestrian route management. Separate foot traffic from vehicle zones at roadworks and construction sites.
Key Benefits
- Portability — empty barriers weigh as little as 15kg
- Stability — filled barriers weigh 400–600kg
- Interlocking — click together for seamless barrier runs
- Stackable — efficient storage and transport
- UV resistant — built for long-term outdoor exposure
- Recyclable — HDPE plastic is fully recyclable

Frequently Asked Questions
How long does it take to fill water barriers?
A standard 1m barrier fills in 3–5 minutes with a garden hose. Larger 2m barriers take 5–10 minutes. Sand filling takes longer but provides more weight.
Can water barriers be used in freezing conditions?
In winter, fill with sand instead of water to prevent freezing and cracking. Alternatively, add a small amount of salt or antifreeze to the water.
How many barriers do I need?
Measure your perimeter length and divide by the barrier size (1m or 2m). Add 10% for corners and overlaps.
