What Is Wall Formwork?
As its name implies, wall formwork is a type of formwork used to construct walls in numerous types of construction applications. Wall formwork can be made of timber, steel, aluminum, or other materials. Steel and aluminum wall formwork are typically prefabricated to particular specifications and can be re-used several times after their first use.
Wall formwork is often modular and comes in various shapes, sizes, designs, and configurations. Wall formwork is frequently engineered according to factors like desired concrete finish. It can be used for small-scale residential projects to large-scale heavy civil projects and for everything in between. Below you’ll find some of the popular applications for wall formwork:
Construction of walls for industrial and residential buildings
Construction of different types of load bearing walls
Shear wall construction
Corner wall construction
Foundation wall construction
Wall construction in existing buildings
Bridge abutment wall construction
In the case of shear wall construction, wall formwork allows for the creation of concrete structures that are able to counter the effects of lateral loads that may act on those structures, including seismic and wind loads.
Modules of wall formwork can be linked together horizontally using clamps for quick and efficient erection of a building or other structure’s walls all at once. Depending on the type of wall formwork, modules may also be linked vertically using clamps to reach desired vertical heights. Wall formwork is often used in conjunction with column formwork and other types of forms to quickly create multi-purpose concrete structures.
High-quality wall formwork should have both high rigidity and stability while also being fairly lightweight. Lightweight wall formwork is useful because it simplifies transportation and use. Rigidity and stability are essential to achieve desired forming results. As mentioned, wall formwork may be prefabricated before arrival to a jobsite, or it may be constructed on site to meet certain requirements of a project.
Timber vs. Steel or Aluminum
While steel and aluminum are often preferred for their efficiency and overall durability, timber formwork may be the preferred choice for wall shapes and sizes that are unique since timber formwork is often built to necessary configurations on-site. As mentioned, steel and aluminum forms can be re-used (sometimes for hundreds or thousands of cycles). Timber formwork is often only used once. Although the upfront cost of steel or aluminum wall formwork is a bit more, these types of forms are actually the wiser choice financially if you plan to use them multiple times or sell them.
Steel and aluminum wall formwork should be properly maintained to retain its value. Proper maintenance includes the use of release agents prior to and after use as well as the removal of concrete residue after use. Additionally, steel and aluminum wall formwork should be stored in a covered, protected area when not in use.
As you can probably tell, wall formwork can play a vital role in various concrete construction projects. It creates precise and strong concrete structures, minimizing errors and speeding up construction. When used in conjunction with other types of formwork, it can considerably enhance the efficiency of a project.
