What is formwork or shuttering?

Formwork or shuttering is an essential part of construction that helps to shape and support the structure during the building process. It is used to hold concrete in place while it sets, providing the necessary support until it is strong enough to stand on its own. In this blog post, we will explore what formwork is, its benefits, and the different types of formwork available.


What is Formwork?


Formwork is a temporary structure that is used to support the weight of wet concrete until it is strong enough to stand on its own. It is typically made from timber, steel, or aluminium and is designed to fit the shape and size of the structure being built. Formwork provides the necessary support and shape for concrete during the construction process and can be removed once the concrete has cured.


Benefits of Formwork

  1. Strength and Durability - Formwork helps to create a solid foundation for the concrete, ensuring that it is strong and durable. It also helps to create a smooth surface that is free from defects and imperfections.

  2. Time and Cost Savings - Using formwork can help to save time and costs in the construction process. Formwork allows for faster construction, as it enables concrete to be poured quickly and efficiently. It also reduces the need for skilled labour, as it is a relatively simple and straightforward process.

  3. Versatility - Formwork is highly versatile and can be used for a wide range of construction projects, from large-scale co


mmercial buildings to residential homes.

Types of Formwork

  1. Timber Formwork - Timber formwork is the most commonly used type of formwork in construction. It is made from timber and is relatively easy to install and remove. Timber formwork is ideal for small to medium-sized construction projects and is often used in residential construction.

  2. Steel Formwork - Steel formwork is a more durable and long-lasting form of formwork that is often used in larger construction projects. It is more expensive than timber formwork but can be used multiple times, making it a more cost-effective solution in the long term.

  3. Aluminium Formwork - Aluminium formwork is a newer form of formwork that is lightweight and easy to handle. It is typically used for high-rise construction and can be erected quickly, reducing the construction time and costs.


Formwork is an essential part of construction that helps to shape and support the structure during the building process. It provides a tempo


rary structure that supports the weight of wet concrete until it is strong enough to stand on its own. Formwork provides many benefits, including strength and durability, time and cost savings, and versatility.



The three main types of formwork are timber, steel, and aluminium, each with its own unique advantages and disadvantages. Understanding the different types of formwork available can help you choose the right solution for your construction project.
