Here Is a Complete, In-depth Overview of Formwork Construction

So, what is formwork construction, in simple terms? Such construction helps get desired structural shape by pouring concrete into the mold. Mold is used to form concrete in different structural shapes like beams, columns, shells, and slabs for building. Formworks are of two types of Reusable formworks, also known as panel forms, and Disposal formworks or stationary forms.

The main purpose of formworks is to give intact support to the reinforced concrete until it has reached adequate strength. Based on materials, the formwork can be of steel, timber, plastic, and fiberglass, where timber is the most common material in formwork construction.

Formwork construction is a process that helps construct buildings. The problem with building construction is the lack of support for the weight of the materials. Formwork solves this problem by creating a sturdy base to use as a foundation for the new construction. Concrete is one of the most popular form of materials used in construction of buildings.

Formwork helps protect the structure of buildings from harsh weather conditions. The process of formwork construction is simple: workers place temporary forms on either side of a foundation and pour concrete into them, creating a solid base. Once it has set the forms are removed and the surface can be finished with other materials.

Required Properties in Formwork Construction

  • Formwork must be strong enough to resist the pressure and weight of concrete.
  • Formwork constructionmust be economical in terms of the total cost.
  • In Formwork Construction, formwork must have sufficient watertight capacity to avoid joint leakages. 
  • Formwork must be firm enough to retain the shape of concrete without any deformity. 

Types of Formwork Construction:

Based on materials, formworks are classified into different categories. These formworks are used in formwork construction to give the desired shape to the concrete

  • Timber Formwork: Timber formwork is one of the most used informwork construction. Lumber and Plywood are excellent materials for timber formwork. Timber provides good thermal resistance to prevent substantial damage in cold areas. Timber is light and can be handled easily and can be cut easily in any required shape. 
  • Steel Formwork: Aluminum, magnesium, and steel are used in steel formwork. In terms of long-term use, steel formwork is economical as that can be reused more often. Steel formworks are easy to fix and used in greater numbers. These formworks are strong enough to carry heavy loads and are more durable than wood formworks. 
  • Plastic Formwork: This type of formwork provides a smooth finish to concrete as they have impermeable surfaces. The carrying capacity of plastic formwork is low and is less durable than steel formwork. Plastic formworks are light and very useful for complex shapes and special features. 

Based on shapes, formworks are classified into the following types used in formwork constructions.

  • Column Formwork
  • Beam Formwork
  • Slab Formwork
  • Wall Formwork

Importance of Formwork Construction:

  • Time Management: Good Formworks reduced the floor-to-floor construction cycle time and lowered the project timings necessary for formwork construction.
  • Good Quality: The type of formworks helps to provide a quality surface finishing and build durable concrete.
  • Safety Concerns: Modern system formworks provide solutions against heavy loads and maintain structural safety and ensure the safety of workers.
  • Project planning: Proper Formwork management helps effectively set movement, maximize reappearance, minimize costs, and timely utilization.


According to the above details, we can conclude that formwork should be made from good quality materials, and it should be properly constructed in formwork construction. The type of formwork materials used in construction depends on the nature of construction, availability of materials, and cost. This article also provides information related to safety concerns, project planning, and the economic importance of the formwork system.
