Things you should know about Wall Formworks
On-site concrete buildings are now often constructed using industrialized vertical formwork. In comparison to conventional formwork, they enable quick and well-defined production cycles and offer higher operator safety during assembly, concreting, and stripping. For concrete wall formwork, a faster concrete filling speed generates greater pressure on the formwork. When using more fluid concretes at significant heights, it is essential to maintain a low filling speed, which the formwork supplier must indicate in dedicated tables.
The vibration of the concrete, which makes it fluid, maintains pressures, and delays setting, is another consideration. The concrete wall formwork may be subjected to extremely high loads by deep vibrations. For instance, it is more challenging to shake the concrete with the typical on-site needle vibrator above 6 m in height. Therefore, external wall-mounted vibrators are utilized, whose location needs to be carefully considered.
Wall formwork can be divided into the following types:
- Traditional- mounted straight on-site using panels and/or wooden strips with steel spacers.
- Steel and/or aluminium prefabricated- modular elements varying in size, assembled using
- closing and clamping accessories.
- Timber prefabricated- used for smooth fair-faced concrete.
- Plastic prefabricated- suitable for the construction of concrete columns, pillars, walls, and plinths.
Uses for the wall formwork system:
1- Residential and commercial structures
2- Walls that support loads
3- Building of reservoirs
4- Construction of shear walls
5- Construction of corner walls

Impact on Construction Sector by Plastic Formworks
Any civil engineering construction includes formwork as a key element. Formwork construction is labor-intensive and can cost as much as 20 to 25 percent of the overall building cost, if not more. Such a formwork is anticipated to be more productive and usable for a greater number of cycles. The Indian construction sector has expanded rapidly, and with the opening of the country’s economy to foreign investment and the arrival of foreign construction firms, it is now essential to have accurate and timely construction projects.
With their benefits including flexibility, durability, and cost-effectiveness, plastic formwork systems have gained popularity recently. The only viable answer to this issue is plastic formworks since it is recyclable, reusable, and environmentally beneficial. The formwork business has recently introduced plastic formwork, which is renowned for its low weight, quick construction, and high level of quality control and assurance in the finished product. This method works well for projects that need to be finished quickly and when the sizes of the columns, beams, and slabs are uniform. These technologies show that this technique is ideal for the building project since it produces better outcomes with more precision and high construction quality in less time and at a lower cost.
Steel and wood are the primary building materials utilized in conventional formwork systems. Time lag and lower precision are the key restrictions of the wooden formwork technology. In a wooden system, the installation and disassembly times are particularly long. Although precision in work may be reached with a steel formwork system, the large weight of the material necessitates the use of a crane, which adds time to the process. Additionally, wood and steel formwork can only be used 10 and 60 times whereas plastic may be used more than 100 times, respectively. Nova provides plastic formwork that is easy to handle and transport on-site, increasing labor productivity.
Thus, it can be concluded that the employment of plastic formwork technology on significant construction projects is cost-effective. It increases building speed and labor productivity. Repetition is far more effective than conventional formwork methods and a greener option than a timber formwork system because it is recyclable. The use of plastic shuttering materials in the Indian construction and building sector has been driven mostly by their affordability, re-usability, ease of use, and that it is lightweight.
Let’s talk about the Column Shuttering
Column shuttering is vital because it aids in the creation of a smooth concrete finish. After the concrete cures, the shuttering oil allows the column formwork to be easily removed. It also increases the number of shutter repetitions.
Column formwork is fashioned and scaled to fit a project’s demands. Clamps, which are horizontal and formed of either steel or lumber, are frequently used in conjunction with column moulds to aid improve quality control during the pouring stage of employing column formwork. The head of column formwork is often used to support the beam. The combination of column formwork and beam formwork allows for speedy and precise construction. Column formwork has two key advantages: it is quick and easy to install, and it decreases the amount of manpower and equipment required to make homogeneous and strong vertical concrete forms of the specified size.
Before fastening the concrete shuttering, a concrete pad called a starter is poured to keep it securely in place and to ensure perfect alignment. The thickness ranges from 45 to 60 mm, and the dimensions are identical to those of the planned column. The starter should be cured for a day or two so that the shuttering surrounding it may be fixed.
Plywood or steel sheets with suitable stiffeners are used to construct the column box or shuttering. To make it easier to remove the column once the concrete hardens, a thin coating of oil or grease should be added to the inside surface of the shuttering. Nova wall panels are multipurpose and are used to make column formwork as well. We offer a conclusive range of sizes which can be added to make any size of columns.
To name a few applications, column formwork is used in corporate, retail, residential, industrial, bridge construction, power plant construction, infrastructure construction, and sewage treatment plant construction. Column formwork is used in most construction projects that involve the development of vertical concrete columns because it helps to build clean, accurate, and robust concrete columns. Once the concrete has been set in the column formwork, it must be extensively examined to verify that it fits the project’s requirements for aspects like aesthetics and strength.
Types of formwork – Pros and Cons
The term “formwork” refers to a mould into which wet concrete is poured to achieve the required shape. It is built from a variety of materials such as wood, steel, fibre, plastic, plywood, and so on, depending on the design, construction, budget, and usage requirements. The main criterion of such a mould constructed of any material is that it must be sturdy enough to handle enormous loads, have leak-proof seams, and not harm concrete, among other things.
The pros and disadvantages of various materials used to create a needed mould are addressed below:
Timber: Timber is one of the most prevalent materials used in the construction of formwork. Timber has been used as a material to manufacture moulds since ancient times as timber, logs, and other items, and it is one of the most cost-effective possibilities when compared to other materials.
Advantages: Because timbers are light in weight, they are easy to handle on building sites; they are also simple to cut to various sizes as needed, and moulds built of timber are simple to deconstruct.
Disadvantages: Moulds made of wood are not as robust as metal moulds since the life of a timber mould is relatively short, thus it cannot be used for a long time.
Plastic: Plastic moulds might be employed in regions where the structure design is intricate. Moulds composed of glass-reinforced plastic are routinely employed in such situations. In other circumstances where the concrete structure is particularly intricate, vacuum-formed polymers are also utilised.
Advantages: Plastic is lightweight, resilient, and long-lasting; complicated design moulds may be easily created from plastic, and old plastic moulds can be recycled and reused. Plastic formworks are also easy to install, easy to dismantle and leakproof.
Disadvantages: Plastic moulds are more expensive than plywood and wood.
Steel: Steel is the most costly material utilised in the construction of formwork. When compared to other types of mounds, this one may be utilised the most times. Moulds of this type provide an extremely smooth and consistent finish. Steel moulds are often utilized in large construction projects such as bridges and dams.
Advantages: Steel formwork has several advantages, including the ability to support a big weight, the ability to be reused a large number of times, and the ease of installation and removal.
Disadvantages: Steel formworks are highly costly; they cannot be framed to the appropriate shape and size; and, since they are composed of steel, they are prone to rust.
