Claim:
A composite wall for retaining a body of water, comprising: a plurality of corrugated metal sheet piles, driven into the ground and connected together to form an undulating wall structure; a base connected to said wall structure and extending therefrom horizontally, said base comprising a steel base frame that is connected to the wall structure and extends away from the wall structure; a backing plate secured to the wall structure and having a vertical surface facing away from the wall structure, said backing plate closing said undulating wall structure, forming spaced apart, vertically extending voids between said undulating wall structure and said backing plate; a plurality of blocks stacked directly on top of said base, such that a weight of the blocks bears directly on the base frame, and forming a facade adjacent said vertical surface of said backing plate; and a first setting material filling said voids formed between the undulating wall structure and the backing plate, preventing water from penetrating into said voids through an upper end of said voids.
