M1 Junction 28 to 31 – Concrete Barrier Renewal

Over 30km of slipform Concrete Step Barrier with over 100 individual handformed transitions

Over 25km of slipform Surface Water Channels with over 1000 outfalls

Upgrade of Great Britain’s life expired steel barrier is rapidly accelerating as the works  are being incorporated within the Highways Agency’s overall program to create “All Lane Running” motorways.


Now rather than 2 to 3km long replacement projects undertaken as a part of routine maintenance significant much greater lengths are being replaced as part of major project framework schemes.An economy of scale is being realised as a direct result of the larger scale projects with productivity and efficiency being improved.

With over 25 years of experience in the UK and mainland Europe Extrudakerb are able to offer Clients the benefit of a wealth of product knowledge and expertise from early design stage, through target cost build up and ultimately construction.

Highways Agency accelerated scheme delivery places high demands on their supply chain where it is vital that the right solution is found to meet challenges that arise and could affect the project programs critical path.

Communication and an ability for the tier 2 specialist contractor to fully integrate into a close knit project team has proved key to meeting Client aspirations.

As the UKs largest specilaised slipform paving contractor Extrudakerb have developed a structured team to interact at every level with Client and project principle contractor. With the largest fleet of slipform paving machines, the largest range of specialist moulds and formwork Extrudakerb are able to provide the necessary level of resource needed to meet and indeed exceed program.

The improvement of the M1 motorway between junctions 28 and 32 represents the longest single section of road works every undertaken in the UK. Extrudakerb and principle contractor Costain built on the success of a similar but smaller adjacent scheme between junctions 32 and 35a of the M1.

Two slipform pavers are being operated simultaneously along with multiple gangs constructing surface water channel outfalls and concrete barrier transitions and terminals.

Outputs are averaging 180m3 of concrete poured daily.

On site permanent project management ensures communication between the Costain, Extrudakerb head office operations management and Extrudakerb on site task supervision is seamless and harmonious.

Whilst this scheme has seen new targets met and new efficiencies realised no one is resting on their laurels and each day new challenges are overcome. This scheme presents an insight into the future for highways improvement works.
