RO water or pure water is water in which there are almost no salts and it is used to cool down some parts of the Mobarakeh Steel Casting Unit. The storage place of this water is a reinforced concrete tank, which a large number of water leakages were visible in the sidewalls and horizontal surfaces around the tank. Therefore, to solve these problems, retrofitting the cracks, finding the cause of the problems, and finding the most appropriate method for complete sealing of this reservoir, extensive studies were carried out by the experts of Kooshe Sazan Mana Company.

For this purpose, after performing analyzes related to the structure and corrosion of concrete and fully identifying the cause of the damage, the feasibility of using different sealing options was investigated. Finally, by performing estimates related to execution, including scheduling and estimation of execution costs, the most appropriate option for sealing and repairing the tank was finalized.
