IBZ-Salzchemie GmbH & Co. KG was founded in 2003 by Dipl.-Chemist Gabriele Ziegenbalg and Prof. Dr. rer. nat. habil. Gerald Ziegenbalg. Since that, we are acting worldwide and have served clients from all continents. We are an interdisciplinary team of nine scientists, engineers and technicians with broad experiences in applied research and development as well as special analytics. Our experiences cover inorganic chemistry, chemical engineering and chemical technology as well as geochemistry and geotechnics. Based on several years of own research and development in 2010 we brought our CaLoSiL® products on the market, which is a new generation of materials for stone consolidation on the basis of nanolime (nano Ca(OH)2). Today, several types of CaLoSiL® are produced together with special lime based paints, mortars and injection grouts. The product range is completed by our ecological mildew and algae remover CaSoPaL®.

While in the start phase we used rented rooms and laboratories, in 2011 it became possible to move into our own company building. On a total area of 650 m2 we have now 8 laboratories with sophisticated equipment available for Research & Development as well as for production. Thus, we are able to realize small scale laboratory tests as well as investigation in the pilot scale range. Our philosophy is to carry out all R&D and consultancy in strong partnership with our clients on the basis of absolute confidentiality.
