How to calculate formwork for a retaining wall?

The construction process cannot function without additional support tools, as well as consumables. This applies especially to wall formwork, without which it is difficult to imagine any concrete wall structure. One-sided formwork is used for building retaining walls, columns, and foundations. Its design features consist of the availability of a modular frame system (buttress): when one-sided concreting is done pressure of concrete is transmitted to the base through the retaining frame. The buttress element facilitates transportation, installation, and operation of one-sided formwork, allowing the accomplishment of work in the shortest time and with less effort.

The difficulty of calculating formwork largely depends on the shape of the concrete form you’re supporting. While a square or rectangular form will be straightforward to calculate and suitable for modular formwork, round or irregular forms may be more challenging and needs to be custom-made.

If we use plastic formworks which can be used several times on the same project or on different projects, this will lower the overall cost. However, the measurements need to be precisely the same each time. Plastic formwork can be reused multiple times, but wooden formwork may not stand up to reuse, especially over long periods.

Formwork is needed to support vertical concrete forms such as walls, columns, pillars, etc. For wall forms, calculate the perimeter of the base and multiply it by the height. Nova Formworks is known for its modular formworks system. Connect with us for your next project!

Plastic Shuttering – The new trend in Construction

Formworks are temporary moulds into which concrete or similar materials are poured. In the context of concrete construction, the falsework supports the shuttering moulds. In the past aluminium, steel and timber formworks were used but they have their own disadvantages. The construction of formwork takes time and involves the expenditure of up to 20 to 25% of the cost of the structure or even more. 

Formwork systems are among the key factors determining the success of a construction project in terms of speed, quality, cost and safety of the works. Nowadays, most projects are required by the client to complete in the shortest time possible as a means to minimize costs with safety. Plastic formwork systems have been creating a buzz in recent times with their advantages including flexibility, durability and cost-effectiveness.

Plastic Formwork in India is a crucial part of the construction industry, it is used as a mould for a structure. Into this mould, fresh concrete is placed so that it can gain enough strength. The Design of these temporary structures is made for economic expenditure. The operation of removing the formwork is known as de-shuttering. 

Conventional formwork made of wood, steel and aluminium bore many detriments, which outweighed the benefits. Wood consumption has a huge and massive environmental impact- deforestation and high price. Moreover, compared to the reusability of plastic, it is very less. Although the reusability index of aluminium forms is satisfactory, the cost factor makes it an unworthy choice. We at Nova Formworks take pride in our plastic formworks, why not try it for your next project?

Let’s Get Into The Details Of Column Formwork!

Formwork is an important part of the construction industry. Column formwork has evolved in the years with so many different types and materials. Column formwork is shaped and sized to the needs of a project, it can be either square or round-shaped. In order to help facilitate quality control during the pouring stage of using column formwork, clamps, which are horizontal and made of either steel or timber are often used in conjunction with column molds. Column formwork’s head is frequently employed to support beam formwork, or column formwork is cast to the bottom side of beams. The use of column formwork in conjunction with beam formwork allows for quick and precise construction.

Two of the major benefits of using column formwork include that it is quick and simple to assemble and that it reduces the amount of labour and equipment needed to successfully produce uniform and strong vertical concrete shapes of desired dimensions. 

Column formwork is used in any type of building construction, retail building construction, residential building construction, industrial construction, bridge construction, power plant construction, infrastructure construction, and sewage treatment plant construction, to name a few areas where it’s applicable. 

Once the concrete sets in column formwork, it is necessary that it is thoroughly inspected to ensure it meets the necessary standards of the project in terms of factors such as appearance and strength. As concrete is being poured, column formwork is often bolstered with the help of falsework. Falsework includes poles or other stabilizing elements that keep the column formwork in place until the concrete dries.

Currently, plastic formworks are the best in the construction industry. They can be reused 100 times and are completely eco-friendly. Nova Formworks is known for its plastic formworks, so what are you waiting for? Let’s reach the height of construction with Nova Formworks.

How Are Drain Formworks Used?

The formwork used when building concrete structures has a significant influence on the quality of the concrete’s surface because it imprints its own texture. The poor quality of formed concrete surfaces is a problem that is widespread in civil engineering and architectural works. In addition to creating an esthetic problem, this irregularity of the surface renders it more vulnerable to elements in the immediate environment. This phenomenon is even more common with structures exposed to harsh weather.

When pouring concrete, the operation which consists of uniformly spreading the mix inside the formwork through the use of vibrations leads to a migration of excess water to the surface, which weakens the primary layer. Often watertight, the formwork does not allow for the drainage of bleeding water that remains on the periphery.

Drainaform is composed of a single textile layer with two different surfaces. The smooth side, which is in contact with the concrete, serves as a filter and prevents the washout of fine cement particles. The fibrous side acts as a drainage component to remove excess surface water and air. Helping to maintain the water-cement ratio and minimize laitance problems, it also helps to improve the strength and durability of the top concrete layer, in addition to giving it a more uniform appearance. In short, Drainaform helps to effectively protect the concrete against aggressive elements such as water, de-icing salts, and freeze-thaw cycles.

Nova Formworks provides the best quality drain formworks. We are known to be one of the best Formworks providers in the industry, this company’s inception dates back to 2004. Connect with us for your next mega project.

Useful Construction Tips for Concrete Column Formwork

To retain the concrete shuttering tightly in proper position and for correct arrangement, a concrete pad known as a starter is cast before settling the formwork. The density will be approximately 45 mm to 60 mm and the dimensions will be exactly equivalent to the dimensions of the projected column. The starter is to be cured for a day or 2 so that it becomes strong to set the shuttering around it. Formworks for columns are formed with plastic, plywood sheets or steel sheets fabricated with plenty of stiffeners.

A thin film of oil or grease should be included with the inner surface of the formwork so that the column can be detached smoothly once the concrete gets solidified. Shuttering should be arranged perfectly and vertical. The diagonals should be examined to verify whether the dimensions are correct.

Formwork should be comprehensively supported with props size before pouring the concrete to resist its movement horizontally or vertically throughout concreting. The gaps close to the shuttered joints should be sealed so that there is no leakage of slurry. Column formwork is shaped and sized to the needs of a project. In order to help facilitate quality control during the pouring stage of using column formwork, clamps that are horizontal and made of either steel or timber are often used in conjunction with column moulds. Column formwork’s head is frequently employed to support beam formwork, or column formwork is cast to the bottom side of beams. The use of column formwork in conjunction with beam formwork allows for quick and precise construction.

Appropriate space should be arranged in the inside face of the shutter and reinforcement by setting up cover blocks of about 40mm. The formworks should be detached after a day of casting and if it is required to detach them previously, they should be kept up to at least sixteen hours.

Two of the major benefits of using column formwork include that it is quick and simple to assemble and that it reduces the amount of labour and equipment needed to successfully produce uniform and strong vertical concrete shapes of desired dimensions.

Types of Formwork Shuttering for Concrete Construction

Concrete is one of the most widely used construction materials, thanks to its exceptional properties. However, to create building elements with concrete, it must be poured into a specially designed mold. This is known as formwork or shuttering.

Concrete Formwork can use temporary or permanent molds, which hold the poured concrete in shape until it hardens and achieves enough strength to support itself. Formwork can be classified in many ways:

• Type of material used
• By the concrete element supported
• Removable or permanent

Formwork has a fundamental role in concrete formwork. It must have enough strength to bear all the loads present during casting operations, and must then hold its shape while concrete hardens.

When selecting formwork it is important to consider the type of concrete and the pouring temperature, since both affect the pressure exerted. Also, Concrete formwork must be capable of resisting the loads of wet and dry concrete.

Concrete Formwork requires structures such as poles and stabilisers to avoid movement during construction procedures, and these are called falsework. To ensure high quality when working with concrete, a qualified workforce and adequate supervision are necessary.

Types of Formwork Shuttering 

Steel formworks:

Steel forms are stronger, durable and have longer life than timber formwork and their reuses are more in number. Steel forms can be installed and dismantled with greater ease and speed. The quality of exposed concrete surface by using steel forms is good and such surfaces need no further treatment. Steel formwork does not absorb moisture from concrete. Steel formwork does not shrink or warp

Aluminum formworks

Often used in prefabricated formwork, that is put together on site. Aluminum is strong and light, and consequently fewer supports and ties are required. The lighter sections will deflect more, but this can be avoided by simply following the manufacturers recommendations.

Plastic formworks

Glass reinforced plastics and vacuum formed plastics are used when complicated concrete shapes are required. Although vacuum formed plastics will always need support, GRP can be fabricated with integral bearers making it self supporting. Like steel, plastic formwork can be reused many times, as long as care is taken not to scour the surface whilst vibrating the concrete.

Steel Concrete Formwork for Concrete Wall, Beam, Column

Steel formwork features large steel plates secured together with bars and couples known as falsework. Using steel is a good choice for builders because steel will not bend, warp, or otherwise become misshapen during the concrete curing process.
One of the most exclusive applications of Nova Formworks is our concrete cast in situ systems. This involves the process of manually pouring concrete in liquid form into our plastic moulds to create rigid concrete on site. The reinforcements can be customised to suit the requirements of the clients. Our panels can be attached to each other with locking wedges and pins without any gaps and are very sturdy. Hence, there is no leakage of concrete and the finish is very smooth.
Steel formwork can save costs and bring environmental benefits to the construction process.
Creating steel formwork requires a minimal production process. There are many ways to make steel, one of which is computer modelling. The digital modelling process ensures that the steel is formed correctly the first time it is created and formed, thereby minimizing rework. If the steel formwork can be manufactured quickly, the speed of fieldwork will also be accelerated.
Due to its strength, steel is suitable for extreme environments and severe weather conditions. Its anti-corrosion performance reduces the possibility of accidents for building builders and residents, thus providing a safe environment for everyone.

Beam formwork – All architecture and design manufacturers

Formwork in concrete construction is nothing but a mold for a structure where fresh concrete is poured with the purpose of solidifying it consequently. Types of formwork for concrete construction are based on the material of formwork as well as the type of structural element.

Formworks are also categorized based on the type of structural member construction like slab formwork to be applied in the slab, beam formwork, and column formwork to be applied in beams and columns respectively.

Beam formwork is generally formed with either timber or metal panels. In this type of formwork, the process is to produce a box surrounded by frames at the perfect size of the beam and fasten it firmly on the kicker left from the base or at the last phase of beam concreting. The box is held in an exact position with steel column clamps or bolted yokes and supported with timber studs or props.

Wellmade beam formwork is a type of steel formwork material.  It is formed from high-strength steel. This type of steel beam formwork is designed for peri formwork. It is used in both slab and beam shuttering in construction.

You can find all components and accessories of the modular beam formwork system here including beam angle brackets, adjustable forkhead jacks, etc.
