Pros and Cons of MIVAN Aluminium Formwork
MIVAN technology is an aluminium formwork system that was originally developed by the Europeans. The name “MIVAN” was derived from the company Mivan Company Ltd based out of Malaysia, as they were the debutants in the manufacturing of these formworks and the prevailing one.

MIVAN in India:
The use of this technology was not popular and extensive in the past, but the trend is changing. High rise projects by prominent builders are constructed with the aluminium formwork to meet the growing demand for housing units by the people in the country.
Being extremely popular in rich Gulf countries, developed Asian countries and all over Europe, the technology is not really new in a global scale. However, with the recent need to cover affordable housing for all the people in India, the technology is being implemented to ensure fast and quality construction that coordinates with the growing demand. Even in Chennai, there are flats for sale in Pallavaram Thoraipakkam Road that are being constructed in this method to counter the growing demand of housing units in the city.
The process of MIVAN construction:
- At first, a wall reinforcing steel is set up to give form to the structure and support the concrete till it arrives at half of the necessary strength value. Formworks made of rugged aluminium are cast intricately around a factory-made mesh made of steel.
- Then, prefabricated slabs and walls are erected along the prevailing reinforcing steel. These easy to handle slabs are made to perfection with aluminium alloy. Other spaces for doors, windows, stairways, etc. are incorporated in the structure and the forms are connected using pin and wedge method.
- At the third and final stage, concrete is poured into the casts. After the concrete gains shape and form, the cast is detached to result in a structure of concrete reinforced with steel.
Pros of using MIVAN technology:
- By using MIVAN technology, one can ensure fast and efficient construction process without compromising on quality. The pace of the construction technique is extremely quick when compared to conventional construction methods, especially in high rise structures.
- The quality of the final structure is excellent because of the simultaneous process of casting the structure and supporting walls. The lifetime of structures built with MIVAN exceeds than that of conventionally built structures. Earth resistance of these structures is also higher than regular ones. Apartments in Pallavaram Radial Road being built by Alliance Group has an expected lifetime of 99 years owing to this strength and quality in construction.
- The finishing on the resulting structures is always smooth in this construction method. Smooth finishes look aesthetically pleasing and also ensures good quality of the structures.
- With no brickwork needed, MIVAN requires fewer workforces and it also requires fewer materials as they allow reusing and recycling.
- Structures formed using these aluminium formworks are so strong that they do not necessitate regular repair works. Maintenance costs for these structures are cut down considerably because of the same reason.
- The formwork made of aluminium allows reuse and they can be used for more than 200 times. They can also be recycled into other products after repetitive usage owing to their strength and versatility.
Cons of using MIVAN technology:
- The aluminium formwork construction method is expensive than conventional ones as the initial cost of the process is very high. But the reduced time, quality of construction and need of fewer workforce balances the cost.
- The method can only be implemented in structures that are uniform and symmetrical in type. Alterations cannot be made in different floors according to different wishes and needs.
- At the beginning of the construction process, the initial setup takes most of the time. The ground floor/stilt levels of high rise buildings take a long time when they are constructed using aluminium formwork method.
- For precise alignment and safe construction practices, only skilled labour can be used in this type of construction.
- Wall tie holes need grouting with GP2 material to prevent leakages in the columns of the structures.
