    Abstract: A flow-through concrete edge forming system utilizes a body member that has perforations thereon. The body member is placed at an elevation transition area of a monolithic slab as an edge forming form. Once the slab is poured, a parge coating is placed on the outer surface of the body member such that the parge coating either binds to the outer surface or penetrates the body member through a series of perforations on the body member in order for the parge coating to bind with the concrete of the slab which has yet to set thereby producing a clean and solid finish of the outer surface of the slab at the transition area. The body member may have either a rectangular profile, a keyhole profile or may have the perforations on a series of inwardly directed deformations.
