One of the main issues in the construction, maintenance and operation of reservoirs is the problem of sealing and solving problems caused by fluid leaks in the reservoir. Large volume tanks, in terms of the type of structure, are divided into two categories of concrete and metal tanks. Depending on the structure of the reservoir, various methods are used to prevent leakage. Leakage in reservoirs leads to waste of costs as well as damage to reservoir structures and surrounding structures. Timely correction of leaky weaknesses and damage to resulting instruments can prevent general damage, human injury and rebuilding costs. The general method of sealing the reservoirs involves checking the cracks, finding the cause of creating fluid spill springs around the reservoir, and providing a suitable method for complete sealing of the reservoir. One of the main problems of fluid leaks, especially water, is the formation of corrosion in structural elements such as steel sheets and reinforced concrete reinforcements, the structure of the structure of the reservoir and surrounding structures, the volumes of invading ions in the structure. Avoiding the use of temporary non-standard methods and the use of world-wide techniques and techniques, taking into account the effects of fluid in the reservoir on the sealing data, can reduce the cost of sealing, the reliability of the method during the operation time of the structure Greatly increase.
