This study aims to develop a healing method of fractured rock by injection of cement powder and carbonated water to form carbonated minerals. The in-situ hydraulic tests were carried out to confirm the effect of their injection into rock. The decrease of hydraulic conductivity was recognized after the injection of both cement powder and carbonated water, whereas the injection of only carbonated water did not induce the decrease of hydraulic conductivity.
