PROBLEM TO BE SOLVED: To provide an existing revetment repairing method which is applicable to joint repair of a gravity revetment of a different type. SOLUTION: According to the existing revetment repairing method, bagged mortar 10 is placed into a back-filling layer 2 on a rear side of an L-shaped block 1 constituting the existing gravity revetment 3, by using a sheath pipe along a joint 4 between the blocks 1, and the bagged mortar 10 functions to block a gap at the joint 4 between the blocks 4. According to the method, the gap at the joint 4 is blocked on the rear side of the blocks 1, and therefore the joint 4 can be effectively repaired even if the method is applied to a revetment structure having only a thin wall thickness like the L-shaped block 1 or a revetment structure having a wave absorbing section of a permeable structure on a front surface.
