Types of Formwork Used in Concrete Construction
Concrete is one of the most popular building materials as it’s safe, durable, sustainable, and economical. Formwork is an essential material used in concrete construction. Formworks are temporary or permanent molds that cannot be removed until the concrete is shaped into the designed structure.
There are many types of formwork used in concrete construction.
Timber formwork is one of the earliest types of formwork. It is typically built on-site and while it is easy to produce. But it has a shorter service life. The installation of timber formwork is very time-consuming. Today, timber formwork is still used in countries where labor costs are low.
This type of formwork is built from prefabricated modules with a frame typically made from aluminum alloy. In comparison to timber formwork, the Aluminum Formwork System can be constructed much faster (using pins and clips) and has lower costs since it can be reused thousands of times.
As the name suggests, this type of formwork is made from lightweight and robust plastic. This type of formwork is an excellent choice for small but repetitive construction projects, such as low-cost housing estates. The plastic formwork system has many applications in the construction industry.
