The Variform Curved Wall Formwork System is a flexible solution designed for constructing closed circular walls or partially curved structures in the horizontal plane.
It can be used for both single-pour and multi-stage casting operations.
The system is engineered to increase efficiency, reduce costs, and save time through its modular and adjustable design.

Maximum Concrete Pressure Range

The Variform system is designed to safely resist concrete pressures within the range of 40 to 90 kN/m², depending on the configuration and assembly spacing.

Wall Dimensions and Radius

The system is suitable for a wide range of circular and curved wall dimensions, with the following minimum radius limits depending on the plywood thickness used:

Plywood Thickness                             Minimum Radius
          12 mm                                                 1.50 m
          15 mm                                                 2.25 m
          18 mm                                                 3.20 m

These parameters ensure optimal surface finish and structural performance.

System Handling

The system is designed for crane handling, enabling efficient use on both small- and large-scale construction sites.
This feature improves productivity and minimizes manual labor requirements.

Accessories

A comprehensive range of practical accessories is available to simplify site work, enhance adjustment accuracy, and improve assembly speed and safety.

Applications

The Variform Formwork System is suitable for a wide variety of curved concrete structures, including:

• Circular and curved walls
• Water treatment tanks
• Large-diameter columns
• Bull-nosed bridge piers
• Circular shafts
• Silos

Panel Roundness Adjustment

The panel curvature can be set to the required radius quickly and accurately using a simple adjustment mechanism (refer to page 63 for details).

Panel Connection

Adjacent panels are connected vertically and horizontally using standard connectors, allowing quick and secure assembly with precise alignment.
