What is concrete formwork?
Concrete formwork is a temporary structure or mould used to shape concrete as it cures. It holds the wet concrete in place, allowing it to harden into the desired shape. Formwork is essential in nearly all concrete projects, from footpaths and slabs to structural walls and columns. It ensures clean lines, accurate dimensions and a safe pour. Once the concrete sets, the formwork is removed. Good formwork is strong enough to support the weight, properly sealed to prevent leaks and carefully aligned to achieve a smooth, uniform result.
What materials are used in formwork?
Formwork can be made from several materials, each suited to different types of projects. Timber is commonly used for smaller jobs due to its flexibility and ease of use. Plywood is often added for a smooth finish. Steel and aluminium are used for larger or repeatable jobs, offering strength and reusability. Plastic systems are lightweight and suitable for modular work. The choice depends on factors like budget, scale, required surface finish and how many times the formwork will be reused. Each material offers a balance between cost, durability and ease of handling.
Why is proper formwork important?
Formwork plays a critical role in shaping and supporting concrete during the curing process. If it’s not built correctly, it can shift or collapse under the weight of the wet concrete, leading to misshapen pours or safety hazards. Gaps in the formwork may cause leaks or surface defects. Alignment and bracing must be checked to ensure the finished structure meets the design. Properly constructed formwork saves time, reduces waste and results in a clean, high-quality finish. It's one of the most important steps in ensuring a successful and professional concrete outcome.
