Slipforming

Why use slipform?

Slipform is undoubtedly the fastest and most economical construction method available for high-rise concrete structures. The technique offers a construction rate of 4m-8m per 24h (about 5-7 times faster compared with conventional methods).
Slipform is also a very safe construction method since there is no need for continuous dismantling and re-assembly of formwork by crane during the construction phase– the complete set-up is assembled only once at ground level before “take-off”.

How does it work?

Ever since the first Hydraulically Controlled Slipform method was invented by Bygging-Uddemann in 1943 it has been based on the same basic principles; Hydraulic jacks – continuously lifting a complete formwork with work decks, 25-30mm at the time, 24 hours a day – climbing on embedded steel rods inside the curing concrete. As the concrete gradually cures, the slipform creates a seamless concrete structure in one pour from the bottom to the top.
With the experience from developing numerous of slipform solutions for a variety of concrete structures (silos, chimneys and other high rise towers) Bygging-Uddemann can even present tailor made slipform set-ups solely for the construction of, for example, conical wind power towers as an answer to the demand for a fast, safe and economical solution for the growing wind power industry.

Our reputation is built on slipforming and we’re specialists in all types of traditional slipforming, gantry slipforming and conical slipforming.
