Here in South Africa, we have a wide range of options when it comes to the building- and construction industry, from building teams to widespread contractor companies. These make it much easier for homeowners seeking professional restoration and renovation teams to help them achieve their dream homes (or other structures).

But before visual aesthetics can be enjoyed (i.e. a beautiful house), the mandatory construction phase has to be implemented, which costs time and money. And impacts just about everyone, from the client and professionals working on the project to the environment. 

But have you heard about the Voidcon system? And how it has taken the construction industry in our country by storm?

You are about to…  


1. What is Voidcon?

The new concrete system Voidcon is a permanent formwork system made from galvanised steel profiles that is designed, manufactured, and distributed in South Africa. After these are laid into position on a building site, concrete is poured into them. While the concrete ensures sturdiness, the steel takes care of stability for the structure. 

It was introduced into the market in 2004 already and has been growing in usage and popularity from day one.  

Part of its appeal is the fact that it is suitable for use in the industrial, commercial, and residential industries. And let’s not overlook the fact that it can help to cut concrete costs by up to 60% to save expenses for the client (depending on the type of design), uses considerably less steel and concrete (which are harmful to the environment), and increase turnover rates while reducing project time.

Versatility definitely plays a role in Voidcon’s usage and popularity, seeing as it can be used on any design – curved or straight. All the professionals require are the exact measurements of the project / site in order to ensure tailor-made results for the client. 

The Voidcon system has been implemented in a variety of structures such as factories, warehouses, shopping malls, schools, office blocks, blocks of flats, and residential houses.

4. What makes Voidcon different?

Apart from the list of benefits we just explained, the Voidcon suspended permanent formwork system is also easier and much quicker to install than any other suspended concrete slab system available on the market today. Its appeal is also further enhanced by the fact that it uses at least 30% less cement than other systems, making it one of the more “greener” options for the 21st century. 

The Voidcon system also supplies all the necessary elements itself for every process. Clients are assisted throughout the entire duration of the project, and since there are vendors available in every province in the country, it means client support is always close by. 

5. The three outstanding features of the Voidcon steel decking system

• Permanent Decking: Provides a simple interlocking deck which supports mass wet concrete and other construction loads.

• Composite Action: Acts as permanent shuttering and serves as tensile reinforcement. This results in a composite action with the concrete.

• T-Beam System: The profile design is based on a T-Beam system that provides beams and voids for large reduction in in-situ concrete volumes.
