Shuttering, also known as formwork, is a temporary mold into which fresh concrete or similar materials are poured and compacted to form a specific structure in construction1. Once the concrete has set and hardened, the shuttering is removed, leaving the structural element in place.
The main purpose of shuttering is to provide support to the structure until it can support itself. It helps to maintain the desired shape and size of structural members like columns, beams, and slabs during the hardening process.
Shuttering can be made from a variety of materials, including timber, plywood, steel, and sometimes even plastic. The choice of material depends on factors like the complexity of the structure, cost considerations, and the expected load on the formwork.
It’s crucial that shuttering is designed and constructed correctly, as mistakes can lead to deformities in the finished structure or even structural failure. Therefore, it requires skilled labor and careful planning.
