The first rock caverns for oil storage in Japan have been constructed in Kuji, Kikuma and Kushikino. Although many phenomena could not maintain the necessary ground water level through some cracks and fractures which occurred during the process of actually constructing the rock caverns, we were able to complete the storage facilities into service by the various measures to render water-sealing effective. As a result, it was confirmed that the observation of the flow trends through water passage is most important to secure the water-sealing system. For this reason, we made the classification and evaluation system to be composed mainly of "Evaluating Water Passages" and "Geological Conditions such as Joint Spacing etc.", how to evaluate jointed rock masses with respect to water-sealing. This paper describes the outline of such classification for aiming and helping the development of water-sealing technology.
