The Cobiax Technologies Group, headquartered in Effretikon, Switzerland, is an internationally recognized specialist for innovative void former systems in reinforced concrete slabs. After founding the company in 1997, chief executive Dr. Karsten Pfeffer invented an unprecedented spherical void former module, which led to the breakthrough and paved the path for the distribution of this outstanding new technology and further innovations by the Cobiax team. The idea became market-ready in 2005 – since then they have continued to further develop it into an internationally patented and multiple award-winning technology in building construction, which they have been further researching and defining for years. From 2005, Cobiax-Iran has become the licensed partner in Iran and neighboring countries.
