Precast Concrete Road Barriers

Concrete road barriers are a simple but effective way to ensure safety on roads and prevent your premises from unauthorised access. An interesting historical fact about the road barrier product is that it is also known throughout the world as a ‘Jersey barrier’ or ‘Jersey kerb’. It’s because the US state of New Jersey first implemented them as separators between highway lanes in the 1950s.

A concrete road barrier is built and designed to withstand impacts upon collision, shield vehicles from running off the roadway and protect the area or people they barricade. These movable traffic barrier systems serve as an ideal solution for any place where public safety, security and privacy is a priority.

Dallcon has manufactured and installed precast concrete road barriers and concrete kerbing with consistent value and exceptional service for over 20 years. Our concrete products comply with industry standards and undergo necessary procedures during manufacturing. As such, you can be sure to get reliable and high-quality concrete road barriers, including custom sizes.

Road Barrier Applications

You can use concrete road barrier blocks as:

  • Alternatives to earth retention blocks for preventing landslides.
  • Barriers around water hazards and other dangerous sites. 
  • Blockade components for entry and exit at construction sites.

When a vehicle collides or loses control, a Jersey kerb helps reduce vehicle impact damage. Temporary road barriers also help control traffic flow and define entry or exit lanes on roads.
