Consequently, the formwork must already be available when the necessary steel reinforcement and concrete mix are placed. Proper making of formwork decides on the accuracy to size, strength and surface finish of the concrete components. Formwork is required wherever monolithic concrete and reinforced concrete structures or structural components are constructed, such as for
- solid structures (foundations, columns...),
- structures with special functions (containers, chimneys, hydraulic structures ...),
- structures to meet great statical requirements (bridges, towers...),
- reconstruction of structures,
- public buildings and structures of irregular arrangement.
