A wall formwork system comes in different types. For you to choose the right formwork, you need to understand their differences. To help you out, here several of its types:
1. Traditional Timber Formwork
For this wall formwork, it is created on-site out of timber and plywood. It’s one of the easiest ways to build wall formwork. But, it can be time-consuming if you are planning to build huge structures. Another thing to consider is that the plywood facing often has a relatively short lifespan.
2. Engineered Formwork System
The engineered formwork system is designed based on prefabricated modules with a steel or aluminium frame. It is then covered on the application or concrete side with material that has the wanted surface structure. One of the benefits of using this wall formwork system is the speed of construction. Aside from that, it also has lower life-cycle costs.
3. Reusable Plastic Formwork
If you want to build widely variable but simple concrete structures, you should consider this system. Its wall formwork design consists of panels that are lightweight and robust. These are often the formwork that is used for low cost, mass housing projects. Also, these types of modular enclosures consist of load-bearing roofs. To maximise space, they are stacked on top of one another.
4. Permanent Insulated Formwork
This is another wall formwork that is assembled on-site and often made of insulating concrete forms. This also remains in place after the concrete has been cured. Using this formwork involves many benefits in terms of strength, superior thermal and acoustic insulation, speed, and integrated furring strip for cladding finishes.
5. Stay-In-Place Structural Formwork Systems
This kind of wall formwork is usually built out of prefabricated-fibre reinforced plastic forms. You can see them in the shape of hollow tubes. They remain in place after the concrete has been cured. Also, they are often used for columns and piers.
6. Flexible Formwork
Compared to all the rigid moulds mentioned above, flexible formwork uses lightweight materials and high strength sheets of fabric. Through this, it can take advantage of the fluidity of concrete and thus, create highly optimised and architecturally interesting building forms.
