How are concrete safety barriers made?

Alternative to moulded concrete parts

Edgings, protective barriers on the central reservation of motorways, gulleys to drain water - concrete can be moulded into many shapes. Such concrete profiles can be produced simply and economically using offset slipforming technology

For offset slipforming, material is normally transferred to the filling hopper from a concrete mixer truck. This material is transferred to the offset slipform mounted on the side of the paver by either a pivotable conveyor belt or a pivotable screw conveyor. The slipform produces the monolithic profile as the offset paver moves forward. The range of possible shapes and sizes is immense, from such common shapes as the New Jersey profile to customized solutions.

In lieu of pre-fabricated concrete parts: rainwater gutter produced with the concrete paving method.

Demanding monolithic profiles are paved in a single pass – the image shows a curb and gutter profile.

Contributing to traffic safety: concrete safety barriers effectively prevent serious accidents.

Easily and cost-effectively producing monolithic profiles

Offset applications extend from roadway edgings and crash barriers with a maximum height of 2 m to narrow paths. Offset paving is quick and efficient when compared to manual placement of prefabricated elements.

Job Reports for Offset concrete paving

During a project in Esterwegen, near Papenburg, Germany, the small paver offered a first taste of the extended range of applications it can now cover by paving a 750-metre-long and 2-metre-wide cycle path along a rural road.

Quickly constructing one and a half kilometers of bridge parapets just before the end of the construction season? Quickly completed without stringlines using the SP 15i and AutoPilot.

Continual construction of bridge parapets

Six slipform pavers rebuild Europe’s largest construction site: The Inn Canal was Europe’s largest construction site in the 1920s. During rehabilitation of the canal, state-of-the-art slipforming technology was used.
