What is Formwork?
Formwork in construction is the use of support structures and moulds to create structures out of concrete which is poured into the moulds. Think of formwork as if it were a cake tin. Formwork can also be made using moulds out of steel, wood, aluminium and/or prefabricated forms.
The formwork is built on site out of timber and plywood or moisture-resistant particleboard. It is easy to produce but time-consuming for larger structures, and the plywood facing has a relatively short lifespan. It is still used extensively where the labour costs are lower than the costs for procuring reusable formwork. It is also the most flexible type of formwork, so even where other systems are in use, complicated sections may use it.
