Types of Formwork for Concrete Structures

There are several types of Concrete Formwork Melbourne provides in the construction of concrete structures. They include Stay-in-place structural formwork, wooden formwork, and shuttering. The most commonly used type is steel formwork, which is composed of thin steel plates and small steel angles attached to a timber frame. Steel formwork is much stronger and more durable than timber formwork and does not warp or shrink during construction. Plywood formwork is made from resin-bonded plywood sheets and attached to timber frames. This formwork type is less expensive than steel formwork.


The construction of large concrete structures requires shuttering. Plastic shuttering is the most common type of shuttering. However, concrete shuttering is also necessary for large projects. Formwork is used to create temporary or permanent molds of the concrete structure. These molds can be reused later. These formwork structures help in retaining the shape of the structure. This type of shuttering is also highly durable. Here are the benefits of shuttering for concrete structures:

This is a crucial part of the construction process. The shuttering used should be strong enough to bear the loads during the operation and hold the shape of the concrete until it hardens. Shuttering works as moulds that support the concrete structure and hold it in shape until it hardens. A shuttering mould should be made of a material that does not warp or deform when exposed to the elements. The shuttering joints should be sealed with cement grout to avoid leakage.

Stay-in-place structural formwork

Using stay-in-place structural formwork as a fire-safe and lightweight alternative to steel stirrup reinforcement has potential benefits for building industry. Existing combined systems are not lightweight and fire-resistant, which makes the use of this method more attractive. To address these issues, we investigated the use of high-performance textile-reinforced cement composite (TRC) in the building industry, with particular interest in shear reinforcement of concrete beams. This paper describes the preliminary analysis of TRC and the feasibility of structural stay-in-place formwork.

The benefits of SIP formwork are numerous. For one, it is lightweight, while at the same time it has high-tensile strength. This means that the stay-in-place structural formwork is compatible with a wide range of structures. Moreover, these solutions can withstand large forces and heavy loads while being extremely lightweight. Furthermore, they are a viable solution for projects where a significant amount of concrete is required.

Re-usable plastic formwork

Re-usable plastic formwork is a lightweight alternative to traditional wooden panels and is ideal for concrete constructions. It offers numerous advantages over traditional forms, including a reduced carbon footprint and easy transportation. The reusable plastic formwork is fabricated from two filtering grids connected with articulated connectors. It is easy to use, durable and lightweight, and has excellent mechanical properties. It also eliminates the need for extra cleansers and labour.

Plastic formworks are versatile and can be used for any type of building, from residential to commercial complexes. They are especially beneficial for construction projects in damp and dark areas, where traditional materials could potentially leak or damage the structure. Moreover, they are easier to transport and handle, which makes them the perfect option for building infrastructure. It also saves on construction time. These advantages make reusable plastic formworks the ideal choice for a wide range of construction projects.

Wooden formwork

Choosing the best timber for a concrete structure’s formwork can be a difficult task, but there are several factors to consider. For one thing, lumber tends to absorb water from the concrete, reducing the strength of the structure. Additionally, lumber that absorbs water is also more susceptible to cracking when it shrinks. Other alternatives to wood formwork include plastic, aluminium, and engineered wood. Depending on your budget, you might want to use an engineered wood product rather than plain timber.

Using wooden formwork is a great way to build a structure without having to use steel. For one thing, steel formwork does not need to be refinished. Furthermore, it can be reused. Another benefit of steel formwork is that it is smoother than wooden formwork. Lastly, unlike wood, steel shuttering does not absorb the moisture from the concrete. Steel formwork is also easier to install and remove.
