Varieties of materials used for making concrete formwork depending on availability of material, economical consideration etc. Formwork can be made using one type of material or combining different types of material.
Below are the common types of formwork material used in concrete construction:
- Fabric, etc.
Timber: Timber is a popular formwork material. It has been using from ancient age. We can make concrete formwork using only timber or combining timber with other types of formwork material. Timber is light weight, easy to fix and remove. It’s also economical and available in different sizes.

Steel formwork materials give excellent finishes to concrete surface. Wide variety of steel formwork materials are available in the market for various purpose of uses. See the “List of Steel Shutter Materials“.
Plywood: Plywood is an artificially manufactured wooden material used for making concrete formwork. It is strong, durable and light weight. The availability of different thickness plywood in the market makes it popular for different sizes concreting work. The thickness range of plywood is, from 7 mm to 32 mm.

Plastic: As per experts, depending on the plastic quality, it can be used up to 100 times. The core advantage of this is, it is super lightweight, easy to handle and stack.
Fabric: This is the latest addition to concrete formwork sector. For RCC construction and architectural design work, this is an emerging technology. The flexibility of this material makes it possible to produce concrete at any shape.
Beside these, there are some other materials used for making concrete formwork. Such as, masonry, hardboard, concrete itself. Masonry formwork is used where small concreting work will be done.
