What is wooden formwork?
When pouring concrete, it is necessary to first create a mold to maintain its shape when drying. Wooden formwork is very often used to create this form; These slats of wood or boards are either permanent accessories or temporary, which will be pulled out as soon as the concrete sets. In most cases, the wooden formwork is temporary and is held in place using braces known as false work. Plywood is one of the most commonly used types of wood for formwork, because it is generally cheap and some types of plywood are resistant to water damage. Creating formwork may take some time, so this step of the process is usually done well in advance - sometimes a few days before the concrete is poured. To determine where wooden formwork must be placed, plans or plans will be required, and there must be plants with a false work to hold plywood or other type of wood in place. The plywood used for this task is usually low -cost even if the material must be water resistant as it will beexposed to elements and moisture from concrete. Plywood can sometimes be re -used for more than one particular job.
As soon as the wooden formwork is in place, it can be poured in concrete. Standard remains in place until concrete sets that can last for several days or even a week or more, depending on weather conditions. During this period, concrete is usually covered with a tarpaulin to prevent excessive moisture accumulation. After several days, wooden formwork can be pulled out of concrete. This task is usually relatively easy, although in some cases the wood can stick to concrete, which requires additional effort or tool to pull it out.
wooden formwork is used instead of metal formwork because it is cheaper, lighter, easier to move and usually easier to store. The disadvantage of wood is its tendency to deform or bending. Concrete finally takes the shape of the wood so if the formwork bendsA or deformation, concrete may not be straight. This can be a significant problem for some types of building processes; If straightness is a very important problem, it is usually best to go with more expensive and heavier metal forms.
