- Traditional timber formwork. The formwork is built on site out of timber and plywood or moisture-resistant particleboard.
- Engineered Formwork System.
- Re-usable plastic formwork.
- Permanent Insulated Formwork.
- Stay-In-Place structural formwork systems.
- Flexible formwork.
What is most commonly used material for formwork?

- Plywood as Formwork Material. Plywood which is a manufactured product of timber is also used for formworks.
- Steel as Formwork Material. Steel can also be used as formwork material.
- Aluminum as Formwork Material.
What is reusable plastic formwork?
Plastic formwork is easy to form a structure such as column, wall, slab, or foundation at the location that is wet as it is waterproof. Reusable plastic formwork is way more durable than plywood and can be easily stored after use.
Can you use plastic as a concrete form?
Plastic reusable concrete forms are the most ideal, versatile forms as compared to other edging materials such as wood forms. They will give you the immense versatility to work with tight radiuses and sweeping curves that are common in today’s designs.
What is formwork material?
Formwork is the term given to either temporary or permanent molds into which concrete or similar materials are poured. In the context of concrete construction, the falsework supports the shuttering moulds. Timber is the most common material used for formwork.
Which formwork is best?
Steel forms are stronger, durable, and have a longer life than timber formwork and their reuses are more in number. Steel forms can be installed and dismantled with greater ease and speed. The quality of exposed concrete surface by using steel forms is good and such surfaces need no further treatment.
What are the 6 requirements for quality formwork?
Requirements of good formwork:- For instance, self-weight, weight of reinforcement, weight of wet concrete, loads of workers, and any other loads during and after casting of concrete. It should be inflexibly built and efficiently propped and supported to hold its shape without undue deflection.

What is re-usable plastic formwork?
Re-usable plastic formwork. These interlocking and modular systems are used to build widely variable, but relatively simple, concrete structures. The panels are lightweight and very robust. They are especially suited for similar structure projects and low-cost, mass housing schemes.
What is the purpose of plastic formwork construction?
The primary purpose for plastic formwork construction is the mass production of inexpensive buildings. These structures are commonly built by people living in very harsh or remote locations, such as places with no roads or power and places suffering from natural disasters.
What is formwork?
