Formwork Contractors Articles

Formwork holds liquid concrete in place, while falsework carries a structure's vertical load until it is strong enough to support it. These temporary structures are crucial elements for building reinforced concrete. Are you planning to start your residential construction project very soon? Do you need some information to differentiate between formwork and falsework? Relax - we're here to help you out. In this article, you will learn how formwork differs from falsework, their usage in construction work, etc. Site engineers are responsible for checking the formwork design and ensuring project safety. Weak materials used for formwork and falsework may lead to failure to carry the load.

What is formwork?

Formwork is a temporary structure or mould that keeps liquid concrete in place and provides the desired shape. It supports the reinforced concrete structure until it solidifies and is able to carry its load. The construction of a formwork structure depends on different factors, such as the weight of the concrete and the length of the structure. Engineers consider these factors to calculate the pressure on the formwork structure.

When do you use formwork?

Formwork is used to build a reinforced concrete structure. For example, building columns, piles, slabs, or reinforced concrete staircases required formwork. At first, formwork structures are built to give the desired shape to the reinforced structure. Next, liquid concrete is poured into the formwork mould to dry off and become solid. Reinforced concrete structures are significantly strong to carry the load of the building, maintaining its structural integrity.

What materials are used for formwork?

Different types of materials are used for formwork, including timber, plywood, steel, aluminium, plastic and fibreglass. However, using these materials depends on concrete load, weather and the concrete element of the building. Timber or plywood can be suitable for lightweight reinforced concrete structures. On the other hand, steel, aluminium, and fibreglass have higher load-carrying capacity and are hence suitable for heavy-weight reinforced concrete elements. Aluminium or steel formwork is far more sustainable to use in construction.

What is falsework?

Falsework is a temporary structure used in construction projects to support concrete structures that cannot support itself. Generally, this type of structure is used to carry the vertical load of concrete structures. For example, formwork supports the structural load of bridges, roofs, concrete beams, etc. Like formwork carries the lord of the concrete poured into it, falsework carries the entire load of concrete along with formwork materials. Engineers must carefully measure and determine the exact placement of falsework elements to make them strong enough to carry loads.

Why is falsework necessary in construction?

If concrete bridges are suspended on two points, the falsework supports their load during casting. Similarly, during the casting of concrete roofs, falsework helps to carry the horizontal load of the liquid concrete. Without the support of falsework, concrete beams, columns, roofs and bridges can not be cast. Falsework helps the liquid concrete to settle and dry to become solid.

What materials are used to build a falsework?

Steel, timber, and plastic are common choices for falsework. These materials are strong enough to carry the vertical load of a concrete structure and provide temporary support until the concrete solidifies. Steel falsework is more sustainable for construction because it is more damage-resistant than timber or plastic. However, timber is a more economical choice. It is also strong and durable enough to carry the vertical load of concrete structures.

What are the primary differences between formwork and falsework?

Formwork and falsework are integrated parts of concrete construction. However, there are a few differences between these two elements.

1. Formwork works as a strong mould for reinforced concrete structures; it helps to give the desired shape to the concrete. But, falsework does not work as a mold. Instead, it supports the vertical load of the concrete structure along with formwork materials. It provides stability to newly cast reinforced concrete. VC

2. Formwork is directly attached to the concrete; if it is not strong enough to carry the concrete load, liquid concrete may leak through. On the other hand, a lack of string falsework structure may lead to the collapse of the entire structure.

Conclusion

Formwork and falsework both help in the construction of reinforced concrete structures. But formwork works as a mould to liquid concrete, helping it strong and solidify. At the same time, falsework supports concrete's vertical load when cast along with the load of formwork materials. If you plan to carry out a reinforced concrete construction project, leave the form and falsework with us. We at Formwork Contractors can professionally handle the formwork and falsework tasks.

Formwork contractors have professional expertise in constructing formwork plates on a construction site. Formwork must be placed on the site to carry its loads and loads of concrete. Are you trying to understand the importance of professional formwork contractors in construction? Are you willing to know how hiring professional formwork contractors can be beneficial? This article is for you. We will discuss the role of professional formwork contractors in the UK. We will also discuss how contractors can assess the needs of different types of formwork in construction. Let’s begin our discussion.

What is a formwork contractor?

A formwork contractor takes care of the installation of formworks on construction sites. The installation process of formworks involves professionalism and years of expertise. Professional contractors ensure the safe and secure installation of formwork on-site. Liquid concrete may leak through if there is a gap between formwork plates during installation. Metal formwork plates are to be maintained properly. Contractors regularly maintain the quality of formwork plates to offer you a solid concrete structure. With years of expertise, professional contractors can select different formwork types to construct a building.

Why are professional formwork contractors beneficial in concrete construction?

Professional formwork contractors are an irreplaceable part of the construction industry. They are experts in designing and installing formwork on a construction site to construct slabs, columns, foundations, and walls. Their expertise ensures that the formwork system is strong enough to carry the loads of the concrete. A reliable formwork contractor makes it easier to work with. They have expertise in all areas of construction - engineering, aesthetics, and safety regulations. If you work with a reliable, professional formwork or shuttering contractor, your work should progress smoothly.

What are the different types of formwork?

Formwork types are differentiated based on their materials. These are: Steel formwork, Aluminium formwork, Timber formwork, Plywood formwork, Plastic formwork. The five types of formworks are used in construction to build columns, slabs, foundations, and walls. With that being said, all of these formworks have advantages and disadvantages of their own.

Steel formwork

Steel formwork is the most durable of the five types and comprises thin steel plates. These thin plates are joined at the edges with the other plates to create a formwork system. Professional formwork contractors use nuts, bolts, and clamps to join them together. The initial cost of steel formwork is higher than that of timber or plywood formwork. However, steel formwork becomes economical after a long period of usage. Professional contractors use it to support heavy loads of concrete and construct columns, slabs, etc. Steel formwork supports curved or circular concrete structures. However, over time, steel plates can be damaged, making it difficult to use.

Aluminium formwork

Aluminum formwork is similar to steel formwork. Both are durable and can carry heavier loads of concrete. However, aluminum plates are light and can not carry much heavier weights. Their lightweight makes them easier to carry to the construction site. Professional formwork contractors can use aluminum shuttering plates as an alternative to steel or timber. The smooth surface of aluminum plates builds a smooth-looking outer surface of the concrete.

Timber formwork

It is the most traditional way of building a formwork system for construction. Timber is lightweight and can be carried to the construction site easily. Professional formwork contractors prefer to use timber to support lightweight construction members. Wood's benefit over steel is that the former is more flexible to use in construction. It can be resized to support concrete structures of different sizes and types. That said, professional contractors can not use timber for a long time. It is vulnerable to termites and water. More extended usage in construction results in its decay.

Plywood formwork

Plywood formwork is relatively stronger than timber. Thin sheets of plywood are compressed together with glue to make plywood. It is a lightweight formwork material supporting concrete columns, beams, and other structures. Similar to timber, plywood formwork may not be long-lasting. Professional contractors use plywood because it is cheaper and available everywhere. The cost of carrying heavy steel plates is saved if plywood is used. However, plywood formwork may not be suitable for large-scale and heavier concrete construction.

Plastic Formwork

The latest advancement is using acrylonitrile butadiene sterrene (ABS) panels in formwork. ABS panels are durable and lightweight, which makes them the perfect formwork material. Contractors use them in construction efficiently. It does not stick to the concrete, making it easier to remove. ABS panels have an interlocking design for easier installation. One downside is its relatively low load-carrying capacity.

The role of formwork contractors in utilising different types of formwork

Designing and installing a formwork system is easier if you work with a professional formwork contractor. They can determine specific formwork material to support the concrete members. Depending on the size and weight of the concrete member, the contractor can choose among steel, plywood, timber, or aluminum formwork.

Conclusion

You should hire a professional formwork contractor to install the formwork system. They can advise you on choosing a suitable material for your construction work. Steel formwork has the highest load-bearing capacity, while plastic formwork panels are easier to carry and install. At Formwork Contractors, we provide bespoke formwork solutions.

Formwork is a temporary structure that builds strong structural elements. It is a mould used to build slabs, shells, columns, and beams. If you want to understand more about formwork in construction, read on. In this discussion, we will discuss what formwork is, why it is essential, the importance of formwork constructors, etc. Formwork contractors play a crucial part in construction. Different types of materials are used in formwork contractors supply them to the construction work. Timber, steel, plastic and fibreglass are used in formwork. Formwork adds flexibility to the building construction and helps design the building.

What is formwork in construction?

Formwork is a mould built with timber, wood, fibreglass and steel. It is flexible in design because it can be built on-site as per needs. Any type of shape and design can be built with formwork construction. After the formwork, liquid concrete is poured into the mould to take the structure's shape. The formwork structure is externally supported with timbers. Once the poured concrete becomes solid, formwork contractors remove external support and the formwork itself. Reinforced beams and slabs also use formwork to make them in desired shapes and sizes.

Why is formwork essential in construction?

Formark is essential in construction because it allows formwork contractors to implement architectural designs in reality. Formwork can be used to construct slabs, beams, and reinforced columns. A guide to formwork must mention that it helps maintain a building's structural integrity. Formwork contractors often use solid, removable metal structures to build strong formwork structures. Instead of using timber, metal structures can significantly reduce the wastage of formwork materials and reduce the cost of formwork construction.

What are the different types of formwork used in construction?

There are different types of formwork structures used in construction. Depending on their shape and functionality, they can be called column formwork, slab formwork, beam formwork, etc. These specific types of formwork structures help construct strong and stable buildings. This guide for formwork recognises that formwork helps build structures and improves building aesthetics as well.

Is steel formwork better than timber or plastic formwork?

It depends on the application of the formwork to build specific building structures. For example, steel formwork would be better if columns, beams, and slabs were manufactured using formwork. It is because they still formwork can still be reused in other construction facilities. It can also reduce costs. However, steel formwork limits the scope of creative designing of columns, beams and slabs. Timber and wood can be used to form specially designed columns and beams.

Is there any environmental impact of formwork materials?

The environmental impact of steel formwork is significantly lower than timber or plastic materials. Steel formwork materials can be used long to build beams and columns. There is hardly any waste material generated if steel formwork is used. On the other hand, plastic, wood, and timber cannot be used for a long time. After several uses, these materials do not remain useful. Hence, using new materials has an environmental impact. Formwork contractors prefer to utilise steel formwork for sustainable usage in the construction industry.

How formwork can be used to construct a curved wall?

Supporting a curved structure by formwork is a complex and challenging task. Formwork contractors carefully build a strong structure to carry the lord of curved walls. The structure should be flexible enough for the curved design. It should also have enough rigidity to carry the load of the structure. High-density plywood, aluminium, and steel are commonly used to build carved formwork. These materials have enough rigidity to carry the load of concrete. Formwork contractors can achieve the curved design by using steel.

Conclusion

Formwork is a complex but essential part of construction. Different formwork materials such as steel, timber, aluminium and plastic are used to build a strong structure. Formwork contractors prefer using steel materials to maintain sustainability and reduce costs. With the help of formwork, architects can implement creative structure designs. Flexible yet rigid formwork materials are used to construct curved walls. These are aluminium, steel and high-density plywood.
