Interested to know all about formwork material, here is a list of formwork materials along with their advantages and disadvantages:

Timber as Formwork Material

It is one of the most common types of material and is being used as bracing members from ancient times. This is the reason, timber logs or lumber formwork are also popular as traditional formwork. Timer logs won’t cost you much and you can easily remove the formwork once the concrete is set. Also, timber formwork won’t cost you much and is the most economical of all materials. Since timber formwork is now being used for ages, you also don’t need to train workers for the job.

Advantages

  • You can easily cut timber into any size.
  • Timber is light in weight and hence you can handle the formwork easily.
  • It has a good thermal resistance that protects the concrete from damage in colder areas.

Plywood as Formwork Material

Although plywood is made from timber, it consists of veneer sheets or plies in layers that make it more convenient to use. You can use plywood for the formwork especially for facing panels since it provides a more smooth finish when compared to normal timber formwork. Hence finishing cost falls because of choosing plywood. You can also choose to use exterior plywood that has strong adhesive power between its different Veneer sheets that makes it waterproof. .

Advantages:

  • You can easily find a very large size plywood sheet that makes your construction job easy
  • You can also prepare curved forms from plywood.




Steel as Formwork Material

Though steel formwork may cost you a little more bucks, it is completely worth it. You can reuse the formwork for a longer time than timber or plywood. They also provide a smooth finish to the concrete. For massive structures, you should steel structure in comparison to wood as it is safer and provides greater strength.

Advantages:

  • It makes a durable formwork.
  • You can easily dismantle it.
  • It is easy to fix.

Advantages:

  • It can be easily handled.
  • Plastic has good resistance against water.
