Jersey Barriers for Sale UK — Concrete Road & Event Barriers

Concrete jersey barriers (also called jersey blocks or jersey walls) are heavy-mass concrete sections used for vehicle restraint on roads, at events, and for hostile vehicle mitigation (HVM). Available to buy or hire in the UK with fast delivery on qualifying orders.

What Are Jersey Barriers?

The "jersey barrier" takes its name from New Jersey, USA, where the distinctive sloped-profile concrete median barrier was first developed in the 1950s for motorway separation. The profile has a near-vertical upper section and a sloped lower face — when struck by a vehicle, the slope deflects the tyre upward, redirecting the vehicle rather than allowing it to mount the barrier.

Types of Jersey Barrier Available

Standard Precast Concrete Jersey Barriers

Solid reinforced concrete sections, typically in 1m, 1.5m and 2.5m lengths. Weight: 500–1,500kg depending on size. Require crane or telehandler for installation. Most stable and cost-effective option.

Water-Filled Plastic Jersey Barriers

Hollow HDPE shell filled with water on site. Empty weight: 15–25kg per section. Full weight (water-filled): 200–400kg per section. Quicker to deploy than concrete — connect garden hose and fill. Suitable for events and temporary road management up to 50 mph.

Interlocking Jersey Barriers

Feature hooked or socketed ends to link sections together into a continuous run that resists lateral movement. Essential for any installation where vehicle impact is anticipated.

Applications

• Motorway and dual carriageway roadworks (concrete required)
• Event perimeter security and vehicle exclusion
• Hostile vehicle mitigation in town centres
• Construction site access control
• Car park lane separation
• Temporary no-entry zones

HVM Jersey Barriers

For certified hostile vehicle mitigation, specify jersey barriers with PAS 68 or MASH test data. Standard precast concrete provides significant vehicle resistance through mass alone, but for government, crowded places and CNI applications, certified impact ratings are required. Always verify test data before specifying for HVM purposes.

FAQ

How heavy are jersey barriers?

Standard 1m concrete jersey sections weigh 500–700kg. 2.5m sections weigh 1,200–1,500kg. Water-filled plastic versions weigh 200–400kg when full, 15–25kg empty.

Can jersey barriers be used for permanent installations?

Yes — concrete jersey barriers are suitable for permanent and semi-permanent installations. They're often left in place for months or years at construction sites. For permanent roadside use, highway authority approval is required.

Do jersey barriers need anchoring to the ground?

Concrete jersey barriers are heavy enough to stay in place under low-speed vehicle impact through mass alone. For certified HVM installations, anchor systems are used. Water-filled barriers should be linked together to prevent being pushed apart.
