What exactly is formwork for? A formwork system is used in the building industry to envelope the concrete during casting and contribute to the grip and hardening, that is the two phases the material passes from the fluid to the solid state and develops the mechanical characteristics necessary to perform its function.

The invention of formwork dates back to the early days of our civilization’s construction activities when building materials were much simpler, such as clay.
People have always used formwork to build more or less complex structures, but it is only in recent decades that studies, techniques and materials have enabled us to develop advanced tools.
Over the construction sector you may find a number of different systems designed to meet different market demands and specific needs: formworks for walls, floors, curved walls, pillars and special designs.
In turn, formworks can be categorized according to the materials they’re made of – wood, metals or plastic compounds – and the technology they use: frame, beam and modular.
Frame formworks are composed of a panel and a perimeter, aluminum or steel as it may be, which guards and protects the edges from mechanical stresses. They stand out for their robustness and consequently for their reusability and durability over time. However, they are also easy to assemble thanks to the predefined mounting diagrams.
Beam formworks are composed of planks that support the deck and are adaptable to any project and ideal for surfaces without imperfections when the surface finish of the concrete required is “fair-faced” (béton brut). The assembly is more complex than frames with longer times, but it is also an alternative characterized by higher load capacity and high flexural strength.
Circular formworks are a very versatile category of systems consisting of pre-assembled standard modules that allow you to quickly assemble circular walls with any radius of curvature as happens with ramps, silos, tanks and purification plants.
Special formworks are tools made according to a specific project, where the dimensions fit right in the construction site as needed and more formwork systems can be integrated with each other to enhance their functionality.
The formworks can also be classified for the main function they offer, generally in formworks for vertical structures and formworks for horizontal structures.
Formworks for vertical structures, often also called wall formworks, are solutions adaptable to every need, construction site condition and use to create walls, pillars, elevator shafts, batteries, pulvini, bridges and foundations.

The choice of the most suitable formwork system for your business or single construction project is determined by a number of factors to be considered carefully and professionally: budget and costs, size of the company, number of uses expected, characteristics of the project, type of construction and conditions of the construction site, desired finish, experience of the workers, crane availability, time.
The following is something you should consider prior to commissioning any project:
It is best to always bear in mind every and all formwork types while in the design phase so that you can make the best and most valid decision.
When you are working on any construction project, be it residential or commercial, there is one important thing that you should always remember to do: choose the right type of formwork material. Many people might be wondering about the selection process of the right formwork material and what elements require careful consideration throughout your selection process.
Formworks function as temporary structures used to shape wet concrete into any required dimensions according to your needs. The formwork holds concrete structures until they reach sufficient hardening to support their weight independently. The formwork system provides strength and stability to a project while maintaining safety standards. So, selecting appropriate formwork materials becomes critical as they need to support the construction project’s base effectively. If, by any chance, you choose the wrong formwork material for your project, it could lead to disastrous situations like delays in the project, costly repairs, accidents, and compromises with safety.
There are many work materials that you can select from; each of them has distinct advantages and disadvantages that need to be used correctly. To enhance your understanding of traditional and modular formwork differences, we have curated this article, which will explore formwork types and essential decision-making factors.
Concrete shaping and support require a temporary structure known as formwork. This structure typically comes in two types:
Traditional formwork is the most basic formwork type, and this type of formwork is typically used in both small and large-scale projects. Unlike modular formwork, traditional formworks are built directly on construction sites, which provides it with greater flexibility and versatility. The popularity of traditional formwork is largely because it offers cost-effective and affordable solutions. Some of the common types of traditional formwork include timber, plywood, steel, and even bamboo. Traditional formworks are manually assembled by workers on the construction site, and they can only be used for a limited time period. The more it is used, the more wear and tear it faces.
Modular formwork, on the other hand, uses prefabricated systems, so there’s no need for on-site cutting. They come with a precast mold that makes it easier for workers to assemble the formwork. One of the key factors of modular formwork is that they are designed to increase the efficiency and productivity of the construction process, making it quicker, simpler, and faster. Materials that are often used in making modular formworks include aluminum, plastic, or steel.
In comparison to traditional forms, modular formwork comes in precast panels or molds, which makes them not-so-flexible options to go within complex projects. Their initial cost remains higher when compared to traditional formwork options. But the main advantage of modular formwork is its exceptional durability, which allows it to withstand more cycles compared to traditional formwork.
When selecting the right formwork material for your project, you must consider the project scale along with cost, quality, safety, and project speed. The following factors will help you choose the most suitable type of formwork material for your project.
The scale of your project dictates its size and duration, which, together with complexity, will influence your formwork selection. Projects of substantial size and complexity need formwork materials that combine durability with steel-like flexibility.
Your budget is also a deciding factor in choosing the formwork material. Although modular formwork systems are the most expensive solution available, they offer long-term cost savings, which makes them a worthwhile investment when your budget allows for it.
The schedule and timeline of the construction project serve as essential factors to consider. If your project needs to be completed quickly, time-saving formwork solutions like modular systems are ideal ones to go for. Traditional formwork systems take more time to assemble and operate, making them the right choice for projects with extended deadlines.
This is another key factor in making such formwork durable and strong enough to hold extra weight and pressure. For small-scale projects, going with traditional formworks like wood and plywood is not a bad idea, as they are durable and ideal for light applications. While modular formworks are durable and suitable for heavy applications, they are the best.
The key safety consideration in formwork selection is its strength and ability to provide stable support to concrete structures. Modular formwork systems provide the best option because they prioritize formwork safety during both assembly and disassembly, which minimizes accident risks.
Understanding all the factors that affect the price of formwork is required before considering its final cost. Traditional formwork options, such as traditional formworks, typically cost about ₹250, while modular systems generally range between ₹ 800 to 1,500 per square meter.
Traditional formworks prove cheaper initially compared to modular formworks, yet modular systems become more cost-efficient over time due to their enhanced durability and longer lifespan, which decreases the necessity for new purchases.
By selecting the right formwork based on your budget and project needs, you can ensure efficient construction while optimizing costs.
Choosing appropriate formwork is vital for achieving success in any construction project. A suitable formwork system that boosts both efficiency and structural integrity becomes apparent when you evaluate project scale along with budget constraints, timeline needs, durability requirements, and safety considerations. Traditional construction materials, such as wood and plywood, function well for modest-sized projects, but modular and plastic formwork systems deliver enhanced durability and reusability while being easier to handle, which translates into long-term cost savings.
