Why choose 3m Concrete Barriers?
The 3m precast barrier is designed for projects where speed, coverage, and site security are key priorities.
- Fewer joints – at 3m long, each unit replaces multiple shorter barriers, reducing installation time and the number of joints.
- Slimline footprint – just 450mm wide, making it ideal for tight spaces such as pedestrian routes, events, or urban sites.
- Interlocking security – tongue-and-groove ends offer a stable, continuous run without the need for fixings.
- Stable base – the wider footprint provides better performance on uneven or softer ground.
- No drilling required – cast-in threaded sockets allow secure lifting and optional fixings for brackets.
- Versatile applications – from site demarcation to event safety, these barriers fit both temporary and semi-permanent needs.
With 3m Concrete Barriers, you’ll get:
Response from the team within 4 working hours
UK-wide delivery with offload and placement options
Full technical support, including datasheets and O&M manuals
Longer barriers for faster coverage
When you need to build longer stretches of concrete barriers, the 3m precast option is the most efficient choice. Each barrier, measuring 3m in length, weighs 2,500kg and interlocks easily with the next through a tongue-and-groove joint. The narrower 450mm profile makes them ideal for pedestrianised areas and confined sites, while the increased length reduces the number of joints and speeds up installation.
These barriers are also ideal for large open sites, construction projects, and event management, where quick coverage is needed with minimal plant movements.
