PROBLEM TO BE SOLVED: To provide a method of stabilizing a revetment back face greatly contributing to the improvement of workability and reduction of a construction cost, not to speak of sufficiently stabilizing back-fill and the back face ground against permeate flow and overflow to the back of a dam body. SOLUTION: A recessed part 4a is formed on the upper face of the back-fill 4 at the back of a caisson (the dam body) 3 constituting a revetment, and a net 12 is laid on the top end of the back-fill 4 including the recessed part 4a, and the dam body 3. Stones 11 are then thrown onto the net 12 in the recessed part 4a and piled up almost by the depth portion of the recessed part 4a. The free ends of the net 12 facing in orthogonal directions in the normal direction of the revetment are wound on the piled stones 11, and the free ends are mutually consolidated by a binder 13 to construct a stone aggregate 10 long in the normal direction of the revetment.
