Formworks might not be a foreign term for those who actively follow innovations and technologies used in construction. Some popular formwork types that you might have heard of or are aware of are climbing formwork, plastic formwork, slab formwork, and, of course, wall formwork. Believe it or not, many times, it goes unnoticed by others as just another aspect of construction projects. However, for those who don’t know this, formwork is far more critical than it might seem at first glance, especially wall formwork.
Wall formwork is crucial for any construction project. It is because of the wall formwork that you get to see tall and strong walls that can withstand the pressure. Be it the walls of your house, pillars, or the building sides of other structures, all of these rely on wall formwork.
Wall formwork not only ensures your walls are stable and secure but also makes sure your wall looks visually appealing to the viewers. It helps in structuring the wet concrete till it hardens and can stand on its own.
This guide discusses what exactly wall formwork is and why it is important for the construction process.
What is Wall Formwork?
Wall formwork is nothing but a temporary mold used to support and shape wet concrete. This temporary structure helps the wet concrete hold and support itself until the concrete hardens into a stable and strong structure.
Therefore, without actually using the wall formwork, it is nearly impossible to build walls.
The wall formwork is responsible for ensuring all the walls are of the same thickness and are straight. This helps meet precise specifications and requirements.
Different Types of Wall Formwork Used in Construction
Wall formwork typically comes in various sizes and shapes. In construction, mostly timber, steel, aluminium, or plastic are used to make walls.
Here are some of the common types of wall formwork that are used in modern construction:
Timber Formwork
It is one of the oldest and most conventional forms. The formwork is made using wood or plywood. Moreover, timber formwork can easily be cut into any shape. They are highly customizable, which makes them ideal for both simple and complex designs.
Timber formwork is also lightweight, which increases the speed of the construction process. However, certain disadvantages that make timber formwork less appealing are their shorter lifespan and low tolerance to moisture.
Steel Formwork
Another popular formwork used during the wall construction. Steel formwork is one type of modular formwork; it is based on a prefabricated system. Due to the prefabricated system, the assembly and disassembly processes are quicker and easier. It is commonly used in large projects where it is essential to meet durability and high-quality finish benchmarks.
However, keep in mind that because of its advanced features, steel formwork is more costly than timber formwork. However, this cost is justifiable considering the longevity and durability offered by steel formwork.
Aluminum Formwork
Another form of formwork is somehow similar to steel; however, aluminium formwork weighs less than steel. Because of the aluminium formwork’s lightness, it is comparatively easier to handle and install, reducing the overall installation and labour costs.
Furthermore, aluminium forms do not rot or get rustic, which makes them ideal options for more prolonged use. Just like steel formwork, aluminium formwork has a higher initial cost, which makes them not-so-ideal options for small-scale projects.
Plastic Formwork
Another renowned and well-known modular formwork is plastic formwork. It is a more sustainable and environmentally friendly option as it is processed using recycled plastic material. This reduces the overall construction waste. Not to forget, because of its modular plastic panels, the setting and removal process is quicker and more seamless.
Because of the plastic formworks’ high reusability and durability, it can be used repetitively in different projects. However, plastic formwork is not meant for high-load projects. They are not as durable and strong as steel and aluminium.
Importance of Wall Formwork
Wall formwork is fundamentally essential for constructing a solid wall. Here are some of the reasons why wall formwork has a necessary place in the construction process.
- Wall formwork is helpful in providing the necessary support to the wet concrete. It helps shape the fresh concrete into strong walls that are capable of bearing the load and weight of the structure. While constructing a multiple-store building, wall formwork ensures each floor’s and each room’s walls are sturdy and aligned correctly.
- Moreover, wall formwork makes it easier to meet simple to complex design requirements. Correct shape and preciseness are essential for the aesthetic appeal and functionality of the structure.
- Wall formwork can be easily assembled or disassembled, depending on the type of material and wall formwork you are going with. Modular formwork materials like plastic and aluminum are easier and quicker to set up. It can also be reused in different construction projects as per the requirements.
- The wall formwork also ensures smooth finishes. All of these depend on the type of formwork material you are choosing. Formwork that is made using high-quality materials provides smooth and defect-free finishes. This minimizes the need for additional work like plastering and painting to achieve a flawless finish.
Advantages Of Wall Formwork
Multiple benefits highlight the need and importance of wall formwork in the construction process.
For instance, wall formwork ensures your concrete wall is of the same shape and size that is required accordingly. Basically, it ensures uniformity among all walls.
By using wall formwork, your construction process efficiency increases significantly. It speeds up the entire process, which is very beneficial when working on large-scale projects. In addition to all of these, wall formwork ensures that a stable structure is built that reduces the risk of accidents. This stability is essential when building structures like bridges or tall buildings.
Another prominent feature of using wall formwork is that it provides high-quality finishes. Some forms are also eco-friendly and contribute to greater sustainability. In addition, these formworks can also be recycled at the end of their lifespan, which reduces the construction waste that often gets dumped into landfills. This overall has a positive impact on the environment.
Are There Any Challenges Associated with the Wall Formwork?
Yes, there are certain challenges that come with wall formwork.
Like wall formwork made up of plastic, steel, and aluminium, it has a higher initial cost. This can be expensive for small-scale budget projects. But this cost can be offset by reusability and longevity.
Secondly, to set up the wall formwork, it requires skilled workers, which is quite a daunting task. This adds up to the operational cost of installing and training workers. Furthermore, taking care of and maintaining wall formwork is not an easy task. Improper maintenance can cause warping, affecting the performance and efficiency of the forms.
Moreover, transferring large wall panels can be challenging. This can add up to the overall expenses for transportation and handling. Also, when the wall formwork is set up, it is not easy to change designs or dimensions, which will be difficult and costly.
While certain wall forms can be eco-friendly and sustainable, others are not so environmentally friendly. This can have a negative environmental impact. Wall formwork can also be susceptible to wear and tear if left in or used in harsh weather conditions. This reduces effectiveness, which leads to less precise forms and leaks during the curing process.
Conclusion
Overall, wall formwork plays a crucial role in the construction process.
It is not just useful for shaping the concrete but also ensures the stability, strength, and preciseness of the concrete. Wall formwork guarantees all the walls are uniform, sturdy, and aesthetically pleasing.
Though there are certain challenges, like a higher initial cost, the need for skilled workers to set up, and complex maintenance, looking at the myriad benefits, it outweighs these issues, making it ideal for large-scale projects where durability and quality matter a lot.
Thus, by carefully choosing the suitable wall formwork, you can enhance the productivity and efficiency of the construction process.
