Plywood Formwork Applications & Advantages



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.

Film faced plywood

Film faced plywood is a commonly used panel. Surface film is paper impregnated with a glue/resin. Film faced Formwork plywood have improved resistance to abrasion, moisture penetration, chemicals, insects and fungi. They have a smooth hygienic, easy to clean surface

Applications of plywood formwork

Plywood Formworks are a wide range of construction formwork systems that are economical and manufactured easily. Its areas of application areas are discussed below.

Wall and column

Plywood formwork is used in various shapes in walls and columns of a concrete structure. They are used in different forms such as framed system, area system, side support system, weight framed system, circular system, column system, column system etc.

Slabs

Plywood formwork is used in various shapes. They are used in different forms such as ceiling slabs, formwork for slab tables, drop beams etc.

Infrastructural uses

For infrastructural projects, such as tunnels and bridges, the building process is the factor that substantially affects the choice of plywood sheets. When a continuous flow is important and multiple concrete pouring is planned, the plywood material has to be durable. Therefore customized plywood formworks are used. It is used in different forms such as crane climbing formwork, shaft platform, a configured tunnel system, customized steel forms etc.
