Each of the walls is made of cast concrete reinforced with a rebar cage having a plurality of longitudinally spaced pairs of parallel rebars extending radially from the central hub to an end rebar that extends perpendicularly relative to the parallel rebars. Each end rebar is connected to radially outer ends of one of the pairs of parallel rebars. A seawall comprises a plurality of the walls connected together end-to-end with a cable, and connecting plates fastened to adjacent sections. A form for manufacturing the wall encloses connected rebars and is filled with concrete.
