Formwork used in concreting is a crucial component in the construction industry.  Formwork is used to create a temporary structure that is used to hold the concrete in place until it hardens and can support itself.

What is formwork?

Formwork, sometimes called “shuttering”, can be made from a variety of materials, such as wood, steel, aluminium or plastic.

Formwork is an essential component in the construction industry, and it plays a crucial role in ensuring that structures are built safely and to the required standards. By using formwork, construction workers can create complex and intricate structures with ease, and the end result is a durable and long-lasting structure that is built to stand the test of time.

What is the purpose of formwork?

The main purpose of formwork is to give shape and support to the concrete as it sets.

The formwork supports the weight of the wet concrete and any reinforcing materials, such as steel reinforcement or rebar, until it hardens and can stand on its own.

Formwork can be used for a variety of concrete structures including walls, foundations, columns, beams, stairs, driveways, and slabs.

The different types of formwork and materials used.

There are different types of formwork, including traditional timber formwork, steel formwork, and engineered formwork systems. Timber formwork is the most commonly used type of formwork, and it is easy to construct and dismantle. Steel formwork is more expensive than timber formwork, but it is more durable and can be reused multiple times. Engineered formwork systems are custom-made systems that are designed to fit specific projects.

Steps in the concrete formwork process.

The process of constructing formwork before concreting involves several steps.

  1. The first step is to design the formwork system to fit the specific project requirements.
  2. Once the design is complete, the formwork is constructed onsite.
  3. The formwork is then inspected to ensure that it is level, plumb, and square.
  4. The concrete is then poured into the formwork and allowed to set.
  5. Once the concrete has set, the formwork is removed, and the concrete structure is left in place.
