Ten frequently asked questions about wall formwork (part ...
Industrialized vertical formwork has become a common part of the construction process on on-site concrete structures. They allow fast and well-defined production cycles, guaranteeing greater safety for operators during assembly, concreting and stripping than traditional formwork.

Doubts or questions may arise during its use. Its use is simple, but some technical aspects must be taken into account.
Let’s analyze the 10 most-frequently asked questions about wall formwork!
1.- What is the maximum admissible filling height?
The maximum height for concreting walls with industrialized formwork depends on many factors:
- Maximum design pressure: Each panel type has been designed for maximum resistance to pressure. Industrialized formwork is usually designed for maximum pressures between 40 and 80 kN/m².
- Fluidity of the concrete used: More liquid concretes generate higher pressures. Special attention must be paid when using self-compacting concrete “SCC”. (See question #7).
- Filling time: A faster concrete filling speed generates greater pressure on the formwork. When using more fluid concretes at significant heights, it is essential to maintain a low filling speed, which the formwork supplier must indicate in dedicated tables.
- External temperature: influences the curing of the concrete: the lower the temperature, the longer the setting time and the greater the formwork’s exposure to the load.
- Another factor to take into account is the concrete’s vibration, which makes the concrete fluid, maintaining pressures and delaying its setting. Deep vibrations can subject the formwork to very large loads. E.g. Above 6 m in height, it is more difficult to vibrate the concrete with a needle vibrator normally used on site. External wall-mounted vibrators are therefore used, whose positioning must be studied correctly. (See question #9).
