The type of formwork you choose to use should be in line with the type of concrete structure you want to build. Different types of formwork are made from distinct elements like timber and steel to meet the needs of specific structures. For example, the type of formwork used in the construction of walls is not the same as the one for slabs.
These modifications on formwork are usually made to increase the safety standards and the durability of the concrete structures. The main blunder that concreters make is the use of wrong formwork in the construction of concrete structures. To avoid making unnecessary mistakes that can cause you tremendous penalties and even human lives, it is better to read and understand the following expert’s advice on the type of formwork that will suit the concrete project you have at hand.
1. Steel Formwork
This type of formwork is great for big projects. Here, a large amount of concrete is poured on the plates tightened with bars also known as falsework. This technique makes steel formwork the best choice for building bridges and tall structures like skyscrapers. The steel makes this type of formwork very powerful in terms of carrying weight. Steel formwork is resistant to cracks, splitting, and warping. So if you are looking for a permanent type of formwork that will be perfect to build bridges, parking buildings, skyscrapers and other large concrete projects, then steel formwork is the best choice for you.
However, this doesn’t mean that it is entirely perfect, steel formwork also has its shortcomings too. Steel formwork is;
- Not easy to transport from one place to the other
- Difficult to store
- Might need modifications to achieve other concrete layouts
- You might need the help of heavy machinery to construct tall structures
Why steel formwork? Even though purchase this type of formwork can be very exorbitant, the best thing about it is that you can reuse it as many times as you want. It is very easy to install and remove.
2. Aluminium Formwork
The Aluminium type of formwork has a lot of similarities to the steel type. This type of formwork is great got builders who want the same effects of steel formwork on concrete structures but in an affordable manner. The main difference that this formwork has from the steel type is that aluminium lighter. You can easily transport and use it when compared to steel formwork.
The only shortcoming that this type of formwork has is that once put in place there is no going back, it is permanent. It is perfect in the construction of tall buildings, and bridges.
3. Fabric Formwork
This type of formwork is perfect for building complex concrete structures that have sophisticated shapes like mosques. Fabric formwork is preferred for these types of concrete structures because of its ability to flex. So if you’re looking for a type of formwork that can produce concrete structures with beautiful curves and corners, then fabric formwork is the solution to your problem.
Experts recommend doing comprehensive research on the type of formwork you want to use before using it.
