Slipform construction ascends to new heights.

Formwork engineering at its finest: the vertical slipform system allows for the construction of jointless concrete structures, all with short construction times and high daily rates. As is the case in previous years, the slipforming method continues to be regarded as a reliable and proven formwork method in 2024, making it the go-to method for constructing towers, chimneys, high-rise cores, silos, bridge pylons and other industrial structures with exceptionally high walls made from reinforced concrete with a strong vertical orientation.

PRINCIPLE

Engineering Principles of Slipforming.

Parallel

The formwork is lifted parallel to the reinforcement and surface.

Continuous

A new building is constructed by continuously adding concrete and reinforcing steel.

Hydraulic

The formwork is raised atop climbing tubes by means of hydraulic jacks.

Concrete

Concrete (15‒20 cm) is added without cold joints for monolithic structures.

Fast

The speed of construction depends on the concrete (acceleration, deceleration or even a stop is possible).

24h or 12h per day

The structure can be slipformed continuously for either 24 hours or 12 hours per day.

AREAS OF APPLICATION

Divisions

Cylindrical slipforming

Cylindrical structures, including changes to wall thickness and post-tensioned buttresses, are possible using the slipform construction method. Simultaneous lifting of steel roofs in parallel with the slipform work saves the customer time and money and ensures that the structure is ready when you are.

Conical slipforming

We have further developed slipform technology for application with various building geometries. Tower and chimney structures can be realised quickly and efficiently using this innovative approach.

Hyperbolic slipforming

When it comes to large diameters, conical slipforming reaches its limits. For this reason, we developed hyperbolic slipforming, which can ensure building tolerances even when dealing with large dimensions and low wall thicknesses.

Offshore construction

Conical structures with an inclined axis are an essential further development in slipform construction and were specifically designed to respond to challenging construction situations, such as offshore platforms and wind power stations.

High-rise construction

The construction of high-rises in an urban context is incredibly demanding: cramped construction sites caused by high densification and restrictions to working hours require a fast and efficient method to realise building projects.

Specialised solutions

Due to various factors, such as architectural-geometric and structural requirements, we are often confronted with extreme situations. This is why we include project-based special solutions in our range of services.
