In one of the oldest chemical plants in Poland are two reinforced concrete towers for fertilizer granulation which were built in the nineteen-thirties. These towers have operated continuously in a very hostile environment for about fifty years. The authors of this paper have used ad hoc methods of repair and protection with varying degrees of success for several years. In 2012, the renovation of one of the towers was designed and implemented with a view to its continuous use over a period of twelve years. A new comprehensive method of protecting the tower was applied due to its relatively long-term use. The resulting tower damage, the results of chemical and structural analysis of the concrete and coating stress are presented in this paper. Furthermore, security methods applied by them and their functionality after a few years of use as well as material and construction details relating to works performed to make the tower operational over the next twelve years are presented.
