What is Formwork?
Formwork is the general term given to the mould into which concrete is poured. It is generally made of timber or steel, the surface in contact with the concrete being selected to give the required finish. The strength of the formwork and its associated falsework must be sufficient to support the weight of the wet concrete without significant distortion.
Formwork is generally removed once the concrete has gained sufficient strength though in some circumstances it may be left in place (permanent formwork).
Although timber and steel are the materials most commonly used for formwork, a range of other materials are used, mainly for specialist applications.
