Special concrete construction
Flexibility and perfection

ÖBA has three small slipform pavers, which it uses to construct special structures using the slipform method. We produce around 20 km of in-situ concrete crash barriers and 5 km of kerbs in this way each year. In addition, we also produce special profiles by precisely adapting existing formwork to the required shapes.

Cast-in-situ concrete barriers constructed using the sliding formwork method and their rehabilitation

Cast-in-situ concrete barriers prevent vehicles from veering into the opposite carriageway. This effectively prevents serious accidents.

Sliding-type kerbstones

Kerbstones manufactured using the slip-moulding process are not only more cost-effective than concrete and granite kerbstones. This manufacturing method also allows for the production of virtually any profile in any radius.

Edge paths constructed using the floating method (with troughs)

This technology is mainly used in tunnelling. Its main benefits are short construction times and its flexibility.

Concrete base using the slipform method

A slipform paver is used to create perfectly level tunnel floors. The slipform paver moves along the tunnel segments at an angle of up to 42°.

Slip-form foundations

Foundations cast using the slipform method offer many benefits, particularly when used as a substructure – for example, for precast elements of all kinds. They can be produced in almost any cross-section and, above all, very quickly.

Sliding-construction tracks

The main area of application for concrete trackways is agricultural land that is used by heavy machinery even in wet weather. They are not only more stable than conventional farm tracks, but also considerably more durable.
