RUNDFLEX Plus Circular Formwork

RUNDFLEX Plus Circular Formwork: With its adjustable standard panels, RUNDFLEX Plus avoids cost-intensive reassembly or special formwork modifications.
RUNDFLEX Plus Circular Formwork: The working platforms can be securely mounted to the horizontally-positioned panels. The pre-assembled platforms suit all radii.
With RUNDFLEX Plus, the formlining is screwed on at the rear. This results in high-quality concrete surfaces without any screw or rivet impressions.
A complete working and concreting scaffold programme with platforms, guardrails and access ladders ensure safe working conditions with the RUNDFLEX Plus.
Only a few spindles are used for the rough adjustment of the RUNDFLEX Plus; this can also be done even with fully-assembled platforms.


Being fully equipped with platforms, guardrails and access ladders, constructing circular walls with RUNDFLEX Plus is a particularly safe undertaking. The formlining is screwed on at the rear as far as possible ensuring that very good surface qualities are achieved. Radii greater than 2.50 m are continuously adjustable with RUNDFLEX Plus which means costly modifications are not necessary.

Efficient and rational working operations
with a low number of spindles, easy radii adjustment as well as fast connections and extensions

Low number of ties
with only 0.54 ties per m² of wall area

Safe working conditions
with a complete platform system

With the RUNDFLEX Plus, we only needed half the time compared to conventional circular formwork. This tried-and-tested system reduces material requirements and the work involved, and includes all accessories. The safety equipment is a great advantage and easy to assemble. My team have had absolutely no problems using the RUNDFLEX Plus - it really is good.
