The different types of Wooden formwork
A saw table and nail able material, wood is one of the first materials used for the production of formwork. Due to its texture and its assembly possibilities, wood formwork has many advantages for exposed structured concrete and for structures of complex and non-repetitive shapes. The boards used for the Modular Formwork must be thick enough to avoid warping (27 to 40 mm), made from wood species free of tannin, dry, and stabilized. For certain applications, sanded, planed, or treated wood is used to highlight, for example, the grain. The wooden formwork allows the realization of visible concrete of quality, presenting varied textures. The characteristics of the wood change during reuse (lower porosity, surface wear); these modifications can have an influence on the color and appearance of the facing. The number of reuse of wooden formwork is therefore limited. For large and flat surfaces, the formwork can be made from plywood panels. But it can also be used for small elements of...
