Slip forming (construction method in which concrete is poured into a continuously moving form)

Slip forming relies on the quick-setting properties of concrete, and requires a balance between quick-setting capacity and workability.

Slip forming is used for tall structures (such as bridges, towers, buildings, and dams), as well as horizontal structures, such as roadways.

Construction began in 1961, and was reportedly the first using of the slipform construction method in North America.

Slip forming, continuous poured, continuously formed, or slipform construction is a construction method in which concrete is poured into a continuously moving form.

It is one of few remaining, visible traces of the ambitious municipal projects carried through in the early 20th century, still witnessing the restraints and possibilities of casting techniques anticipating pre-stressed concrete and slipform constructions.
