For a long time, slipforming has been regarded as a reliable method, making it the first choice for the construction of towers and container constructions with walls of exceptional height made from ferroconcrete with a strong vertical orientation.

For slipforming constant cross-sections - or cross-sections which do not change with height - the formwork with all the working platforms, is raised on climbing tubes by means of hydraulic jacks.

The active principle of the slipforming process consists of a quasi-continuous perpendicular lifting process of the formwork construction while all the usual steps are executed concurrently: Forming, reinforcing, placing of concrete and aftertreating.

The formwork grows upwards with the structure up to several metres a day. In general, the works are carried out in 24 hours shift rotations, but slipforming only during the day is possible, as well. The stroke process is carried out in discrete steps of 20 to 25 millimetres in a determined time interval. Slipforming speed is usually between 3 to 5 metres in 24 hours. Neverthelessslipforming speeds of up to 10 metres in 24 hours can be achieved.

Slipforming therefore stands for rapid construction progress, an economical use of resources and the highest possible health and safety standards.
