Concrete is a material that allows for the casting of shapes and sizes in concrete that can be used for various purposes. Precasting requires the concrete to be poured into precast formwork from which it must be easy to remove the cast product for its further use.
Formwork is often a significant cost in concrete work, and the economy of the operation can be ensured if proper care is taken in designing the formwork, so that is easy to assemble, dismantle and also allows it to be used for many times. This need has led to formwork being made with steel, fiberglass and other materials that are extremely durable. The use of high-quality rubber and plastic is not unknown especially for multi-use in the manufacture of tiles where the shape and size of the formwork need to be constant and unvarying.
