Timber is the most commonly used construction materials in the past. It is often used to fabricate props, formwork, scaffolding planks, and scaffolding standards.etc. Timber logs, lumber, etc. are used as bracing members from ancient times. So, the formwork or scaffolding manufactured of timber are also called traditional formwork or traditional scaffolding. It is the most economical material used for formwork. Timber is more accessible for the people in remote mountain area compared to steel or aluminum. Therefore, it is still used in sites as formwork material for a number of years. The methods of constructing timber framework are well known to the workers. 

But why should we not choose timber formwork to apply in the construction project? We should have a look at the disadvantages of Timber Formwork:

1. Timber formwork has limited usage or shorter service life compared to steel or aluminum. So, it cannot be used for many times.

2. Dry timber may absorb water from wet concrete which results in the reduction of strength in the concrete structure. Because of water absorbing, the dry timber formwork may be deformed, which also result in the deformation of the concrete.

3. Wet timber having high moisture content compress the wet concrete and forms cracks in the structure and grout may be leaked through joints when shrinking occurs.

4. The needs for timber will result in a large felled forest, which will cause environmental damage.

Therefore, we recommend using steel formwork or aluminum formwork. These two kinds of formwork are more durable than timber formwork and can be used for many times.
