Plywood formwork is a lightweight, durable and eco-friendly system that provides high quality concrete cast surface. It is prepared by combining the specially prepared three layers on top of each other. Plywood formwork is applicable wherein a large surface needs be coated with a light and durable material. It is especially preferred in molds prepared for pouring concrete in constructions. Usually, plywood boards are made of birch, poplar, spruce, or pine but there are many types of materials used by plywood manufacturers in different parts of the world. While the type of plywood used is important, the real opportunity for making a difference for the final concrete result is the type of coating: the film that is applied on the plywood surface.
Advantages of plywood formwork
Plywood has the natural property to absorb moisture, resulting in a sponge effect. This causes movement of the panels, affects the weight and the mechanical properties of the material, ultimately influencing its life cycle. Its advantages includes
Provides high-quality concrete cast surface
Favorable for weight to strength ratio
Minimal deflection due to inherent stiffness
High durability
Can be reused
The panel shear of plywood is nearly double that of solid timber due to its cross laminated structure.
Easy to machine and fix using standard machining and fastening methods
Easy to handle on-site
Good chemical resistance
Wide variety of different overlays and sizes available
Plywood has ecological importance.
