Formwork is the term used for the process of creating a temporary mould into which concrete is poured and formed. Formwork is an integral part in the Construction process. Traditionally, Formwork is fabricated using timber, but it can also be constructed from steel, glass fibre reinforced plastics and other materials. While Formwork is a broad term that is used in relation to the forming process using a wide variety of materials, Shuttering is a term that is often used to refer to the process of using plywood to form the mould.

Shuttering is perhaps the most popular type of Formwork and is normally constructed on site using timber and plywood. A special grade of water-resistant plywood is required for Shuttering. It is relatively easy to use, although it can be time-consuming when using it on larger structures. It is generally used when the labour costs are lower than the cost of producing re-usable Formwork from materials such as steel or plastic.

When selecting the type of Formwork material, you must consider the type of concrete and temperature of the pour as these factors they both affect the pressure exerted on the mould. The Formwork sides must be capable of resisting the hydrostatic pressure of the wet concrete which will diminish to zero within several hours depending on the rate of setting and curing.

The Formwork base or soffit must be capable of resisting the initial dead load of the wet concrete and the dead load of the dry set concrete. Once the concrete has gained enough strength the Formwork can be stripped (removed). A minimum value of 5 N/mm2 is recommended in all cases when striking vertical Formwork.

A high-quality product requires high-quality workmanship and attention to detail. Inspection of the Formwork before casting is vital in ensuring a high standard and high-quality appearance of the resulting concrete structure. Both Shuttering and Formwork in its various forms will be supported by falsework. This refers to props, beams and other stabilisers that keep the Shuttering or Formwork in place as the concrete dries.

In order for us to provide you with an explanation and to help you in making the right decision about your future requirements in Formwork Construction, we would like to offer an insight into what Formwork Construction Is. Formwork Construction is generally a temporary structure that has the purpose of containing poured Concrete and helps mould it to the dimensions required, then supporting it until the Concrete structure is self-supporting. It is made mostly of the face contact material, as well as the bearers that directly support the face contact material. Falsework is the stronger structure that holds in place temporary Formwork Construction and is used in the temporary condition.


The systems of Formwork Construction used for concrete frame construction continue to develop. The most recent innovations have been surrounding on-site efficiency of health and safety, production and environmental issues, ensuring the concrete construction industry is brought towards ever-increasing efficiency.

A variety of Formwork Construction systems have been producing to provide a range of Concrete construction solutions that are able to be chosen to meet the demands of different developments. Formwork Construction that is traditionally for Concrete construction often consists of bespoke options that require highly skilled craftsmen. The skills the craftsmen require are often steel fixing and carpentry. One of the more important features is the finishing of the Concrete. The kind of Formwork Construction that was made up of purely timber bearers and sheet ply often has poor safety features, with slow rates of construction on-site and large amounts of waste.

The primary types of Formwork Construction systems currently in use are:
System Column Formwork
Horizontal Panel
Slipform
Jumpform
Vertical Panel Systems
Permanent Formwork Used In Some Types Of Hybrid Concrete Construction

The Formwork Construction systems listed here are mainly modular and are designed for efficiency and speeds. The design is intended to provide extra accuracy and reduce waste in construction and most have extra health and safety features built.

So, many people don't really know what formwork is. If you are in the construction business or if you have had outside influence to the construction business, then you will know what formwork is.

Formwork is temporary or permanent moulds that are being used to pour concrete or similar materials in. In the context of concrete construction, the falsework supports the shuttering moulds, which are the support of the vertical surface of the formwork. There are different types of formwork to make use of during a construction project, which are as follows.

- Traditional Timber Formwork: It is built out of timber, plywood or moisture-resistant particleboard. 
- Engineered Formwork System: This formwork is built out of prefabricated modules with a metal frame, for example, aluminium or steel and of which covers the application of the concrete side with material having the wanted surface structure.
- Re-usable Plastic Formwork: These interlocking and modular systems are used to build widely variable, but relatively simple concrete structures.
- Permanent Insulated Formwork: This formwork is usually assembled out of insulating concrete forms (ICF) on site.
- Stay-in-Place Structural Formwork Systems: It usually assembled on site out of prefabricated fibre-reinforced plastic forms.
- Flexible Formwork: It is a system that uses light-weight, high strength sheets of fabric to take advantage of the fluidity of concrete and to create highly optimised and interesting building forms.

what is formwork

Like anything else in life, the construction industry also evolves and improves in many ways, of which many new trends develop as well in the process.

Here are a few new trends that are happening today.

• Single-Design Models
In general, documents that are created by engineers usually are given to the contractors to adjust the information on the drawing according to their working process. But that is in most cases not how the process proceeds. Nowadays, time is most certainly of the essence and new trends need to be implemented and with this, it all becomes in-house from engineering to coordination. Which means that models should go directly from engineering to construction.

• Materials
Materials are being recycled and reused in every way for our environment. For construction, it is not about how good the quality of a material is anymore, but also on how the material is being used for the construction process.

• Energy Efficiency
Everything is dependent on energy and it becomes more and more of a problem, especially here in South Africa. Energy consumption should thus be taken in regards of construction and systems should be implemented, such as systems that recover energy through heat wheels and occupancy sensors.

These are just a few of the new trends that are happening in the construction industry. We can move forward, together.
