Types of Slab Formwork

Types of Slab Formwork

Slab formwork is a key component of construction projects that involve the pouring of concrete. It is used to firmly contain the concrete until it hardens enough to support the weight of any structures that may be constructed upon it. The design and layout of slab formwork can vary according to building requirements and site conditions. However, in general, a slab formwork system will comprise facings, crossings, and girder stringers on props or shoring towers.

The use of slab formwork helps to speed up construction times by allowing workers to enclose buildings more quickly and allow interior trades to begin their work. It also ensures that the structural integrity of a structure is maintained throughout its lifecycle. Choosing the right type of slab formwork for your project will depend on your unique needs, but it should always be durable and strong to ensure a high-quality finished product.

There are several types of slab formwork available on the market, including plywood, timber, and steel systems. Each has its own advantages and disadvantages, with the choice ultimately relying on your preference for upfront cost, lifespan, and labor efficiency. Plywood systems are relatively cheap but have a limited lifespan and are vulnerable to moisture damage, prompting many developers to seek the durability and lower lifetime costs of engineered materials like aluminium or steel systems.

Modular panel formwork systems offer standardized components that can be easily assembled and dismantled on-site, drastically reducing labor costs. They typically consist of primary panels, quick-release dropheads, and lightweight aluminum or timber beams that are designed to interact seamlessly. These systems are commonly employed in large-scale construction projects with the same slab dimensions repeated dozens or even hundreds of times, and their unparalleled speed and efficiency allow them to dominate the modern high-rise construction sector.

In comparison, shoring system slabs are designed for more permanent applications and are typically made from corrugated metal decking or other similar systems. These systems have a much longer lifespan than reshoring, but they do require regular maintenance and repair to ensure continued functionality. A combination of these two types of slab formwork is typically used in high-rise buildings, as they offer the best of both worlds: a rapid installation process and long-term durability.

Slab formwork must be capable of delivering a high-quality finish, and this is where aluminium and steel systems excel. They are highly resistant to corrosion, ensuring a durable and robust final product that can stand up to the elements. They can also be re-used for multiple concrete pours, increasing the overall efficiency of your project. This makes them a popular choice for concrete contractors of all kinds, from small projects to massive infrastructure and high-rise developments. They are also lightweight, making them easy to transport and assemble on-site, further reducing labor costs.
