A method and article of manufacture for building waterproof concrete structures. An integral casing comprised of a rigid plastic shell with an armature attached to its face is covered with concrete. The shell is formed either in the shape of a desired structure or in a generic shape to be used to splice together a larger custom structural shape in a mosaic fashion. The shell acts both as a form to support the wet poured concrete and becomes an integral part of the finished structure to provide waterproofing.
