Formwork Systems for Curved and Circular Concrete Structures

Certain architectural and infrastructure projects, such as dams, car park ramps and septic tanks, require the construction of curved walls. To enable builders to complete these projects successfully, different types of circular formwork systems are available.

MEVA Circular Formwork

Round girder formwork

With this type of formwork system, timber spacers are placed between the timber girders and steel walers. In this way, you can adjust the formwork to the required radius. Round girder formwork is best suited to the construction of multiple concrete structures with identical radii.

Flexible girder formwork

Flexible girder formwork consists of timber/steel girders and a spindle that will enable you to adjust the formwork to meet your project’s specifications without having to reassemble the panels. As a result, this formwork system is ideal for projects that require curved walls with different radii. In most cases, flexible girder formwork is pre-assembled in a “flat” condition before being transported and adjusted onsite.

Polygonal formwork

Polygonal formwork comprises “flat” frame formwork panels that have been repurposed by adding supplementary radius panels and rails. This is why this circular formwork is also sometimes known as frame formwork. Polygonal formwork provides builders with a cost-effective solution when building curved walls. They can be transformed from existing frame formwork systems into polygonal wall formwork by simply adding several accessories.

Circular column formwork

Besides curved walls, some infrastructure projects may require circular columns, especially when constructing piling or elevation of buildings, bridge pillars and areas where the movement of people should not be hindered. Generally speaking, steel or aluminium forms are used to build circular columns as they are available in incremental dimensions and can be easily adjusted to match a column’s dimensions.

Similar to any formwork system, choosing the appropriate circular formwork is crucial as it can have a significant impact on the execution and completion of your project. At MEVA, we urge you to equip yourself with in-depth knowledge to ensure you will achieve the best possible results. To help you make an informed decision, our formwork experts are always available to provide you with the information and/or comparison tool you need.

Radius circular formwork is flexible, dependable and highly suitable for circular walls with a radius of at least 250cm. Quick and easy to install, it allows the precise step-less adjustment of a concrete structure’s curvature. The formwork’s coated steel facing is widely known for producing high-quality and consistent concrete surfaces. With a fresh concrete load capacity of 60kN/m², Radius is reliable at high pour speeds and large formwork cycles. This wall formwork is also compatible with other MEVA products, such as AluStar, StarTec, Mammut 350 and Mammut XT.
