A sealed wall structure includes at least one sealed plate ( 10 ), the plate ( 10 ) being corrugated with at least one first series of corrugations and a second series of corrugations ( 6 ) of secant directions, the corrugations protruding toward the internal face of a tank. The structure includes at least one reinforcing ridge ( 11 ) made on at least one corrugation of a series in its portion lying between two successive intersections ( 8 ) with corrugations of the other series, each ridge ( 11 ) being generally convex and made locally on at least one lateral face ( 6 b) of the corrugation that supports it.
