What is formwork construction?

Formwork is a mold for forming a concrete skeleton, all assembled by hand by skilled craftsmen. The wide variety of complex structures currently being built are the techniques of formwork carpenters.


There are various types of formwork such as wood, steel, and lath, but in most cases wooden formwork is used. Wooden formwork is often used because of its practicality and economy, such as being lighter than steel and being able to be processed into various shapes.
