We have been protecting old building structures from capillary moisture since 1983, when Stevan Oberknežev founded his first company "HIO-HidroIzolacija Oberknežev". After 15 years of experience in work with handsaws and bitumen insulation, in 1997 Stevan started development of the new, revolutionary HIO-technology®. In cooperation with an outstanding team of operatives which gave their suggestions for its implementation improvements, the technology has been completely perfected by the middle of the 1998. Soon enough, it became an all-inclusive protection system of old building structures from capillary moisture. Nowadays, our company operates in the entire region, with our companies in Serbia, Hungary and Romania, with more than 260 churches and hundreds of significant referent objects. Today, our technical proficiency and workload capacity make us completely qualified for doing business on the EU market.
