Transition / termination is constructed using bespoke modular steel formwork that efficiently caters for existing surface preparation, structure profile and transition / termination locations. The system has a unique universal transition / termination unit that facilitates transition to all other safety restraint systems as well as structures that have been suitably assed to withstand direct vehicle impact. The system can be used in a variable, wide, and wide variable profile arrangements and offers a simple solution for crossing and abutting structures. The cost of the new high-performance barrier profile has been found, by an independent research group, to be comparable with lower performance double sided N2 steel barrier systems. There is no need to revisit the barrier to carry out other works, such as levelling and grouting resulting in follow on trades being able to access these locations immediately or indeed the barrier to be exposed to traffic. Within a maximum of 3 days from installation - sooner given moderate ambient temperature, ECB will have gained sufficient strength to provide Declared Performance. The system is manufactured insitu under Factory Production Controls at the point of need this represents the most efficient lean manufacturing process, and unlike precast barrier systems avoids the need for shimming, grouting, repetitive mechanical lifting and double handling.Ĭoncrete mix design is tailored to meet the environment and location in which the barrier is being constructed to ensure a right first time quality product. The system also benefits from a reduced upper foundation thickness and can also be surfaced mounted. The system is fully CE marked with a Declared Performance of H2 / W1 / VI2 / ASI B, without the need for a longitudinal steel strand.

Extrudakerb Concrete Barrier - ECB, the world’s first high performance maintenance free concrete barrier to deliver H2 containment and W1 working width without longitudinal cable or reinforcement strand with the smallest cross sectional area of any concrete barrier system.ĮCB is a high-performance concrete barrier system with sufficient design and construction parameter flexibility to accommodate project constraints, rather than a barrier system where the project design and construction must be adapted to facilitate its inclusion.The first wide barrier acting as a street lighting foundation on the M25 motorway at the A2/A282 interchange.The first Britpave Concrete Step Barrier on the M62 motorway at Howden.The first variable profile barrier on the A720 Edinburgh City Bypass.

The first ultra high containment (H4a) on the M4 motorway at Slough.

In 1992 the first Vertical Concrete Barrier on the A47 Narborough Road.

Extrudakerb have for almost 30 years led this evolving sector pioneering first UK slipformed road restraint systems
