A formwork serves as a temporary mould for a certain structure. Formworks can be made from different kinds of material such as wood, concrete and many more. Choosing the material to be used on the formwork depends on the type of structure being constructed and the budget. Read along to know more about the different kinds of formwork and how they are used in a construction project.
Timber is the traditional material used for formworks way back the ancient times. Many people opt for timber formwork because it is cheaper than other material. It is also easy to handle – from cutting, weighing, assembling, dismantling, and replacing damaged parts. This kind of formwork is best used for only a limited number of times because they wear down after a few uses.
Just like timber, plywood is also a versatile material for formwork. However, plywood offers a smoother finish compared to timber which makes it a popular choice for modern construction projects. The plywood used in formworks is called exterior plywood. Unlike regular plywood, this one is waterproof so there’s no need to worry about the moisture seeping into the structure. When using plywood formworks, make sure to use the appropriate thickness based on the weight of the structure it will support.
Steel is one of the most durable formwork materials. Although this material is more costly then timber or plywood, the price is worth it because it can be reused over and over again. Steel formworks are very strong and durable, making them the perfect ones to be used on huge structures like bridges. To make a steel formwork last longer, be sure to keep it away from moisture as much as possible. To save on expenses, don’t make your own formwork; get a formwork hire Sydney instead. You can be assured of the quality of every formwork because it is made by the experts.
Aluminium is commonly used in pre-fabricated formworks. It is also strong and durable, making it good for heavier structures. Just like steel, it can be used and reused a lot of times. When using aluminium formworks, the weight of the load should be properly considered because this material can deflect when it reaches it load capacity.
With so many innovations in construction technology, plastic can now be used as a formwork material. Plastic is very versatile and can be shaped into almost anything and any size. They are also lightweight, water-resistant and also reusable. Plastic formworks are usually used on light or smaller structures and sometimes on complicated concrete structures to achieve the complex design. Unlike the previous materials, plastic can’t handle very heavy loads.
Fabric is the latest type of formwork material. It can be formed into various shapes no matter how complex it is. After the concrete s dried, it can be removed easily. However, it is complicated to use so you’ll need skilled workers to handle it.
Make every construction project perfect by choosing the right type of formwork to be used.
