Doka is one of the few formwork manufacturers who also produces and distributes plywood sheets for our customers thus helping them optmise overall construction costs, speed and quality of project execution. We provide a diverse and region specific range of plywood sheets to be used for various applications at the construction site. Whether for formwork, infill zones or just to set up the construction site our range of formwork sheets covers many applications and formats. Our comprehensive portfolio of plywood boards and supporting services allows construction project managers to make a smart choice by sourcing the right combination of plywood material depending on its use.

Usually wooden 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 wood 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. Wood 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.
Selecting the right type of coating while taking into account the application would determine the consistency of the quality of the concrete and the cost efficiency of the project.
Slab and wall formwork used in commercial, residential and high rise construction often determines the choice of plywood panels to be ordered. Plywood used in slab and wall formwork can wear out more quickly due to the heavy use of floor surfaces or due to the multiple reuse cycles expected for wall formwork. Therefore, it would be wise to invest in more durable panels if you would like to achieve lower cost per use. It has been determined that a higher number of reuses of the plywood would affect the architectural requirements of the resulting concrete surface.
When undertaking projects, such as tunnels and bridges, the building process is the factor that substantially affects the choice of plywood sheets. When continuous flow is important and multiple concrete pouring is planned, the plywood material has to be durable enough to be reused many times (often more than 50).
In bridge construction, there are special factors to consider as well: the need for strong reinforcing, many pouring stages and long periods between the pouring stages. It is crucial to plan for shrinking of the plywood and avoid inappropriately used plywood to affect the quality of the concrete or the duration of the project.

It is easy to overlook some aspects of the construction project where workers end up using plywood material. Real world practice shows that plywood is often used in more simple applications such as the setup of the construction site - temporary constructions assisting the building up, site fences, dust walls used for protection or separation of certain areas of the building, as well as in many other supporting functions.
Rising walls and structures is not always straightforward: different forms, infill areas or box outs complicate the process. In loose application, using the same high-class plywood sheets purchased for the concrete pouring application is not cost effective. There are plywood sheets with no coating or with basic properties such as natural plywood that fit perfectly such usage.
Construction projects with very high architectural requirements the plywood would need to possess certain qualities such as durability against scratches and vibrations and large size panels, a very smooth surface, or a surface with a specific pattern. If a plaster or paint has to be applied on a smooth concrete surface the plywood sheets would have to possess certain characteristics.
If the concrete face will be left as it is, you might consider plywood that is specifically manufactured for fair-faced concrete surfaces.
Plywood sheets comes in a variety of sizes, grades and classes. Choosing the right combination is crucial for the cost effective purchasing of the plywood material.
