<p>A flow-through concrete edge forming system (10) utilizes a body member (12) that has perforations (20) thereon. The body member (12) is placed at an elevation transition area of a monolithic slab (S) as an edge forming form. Once the slab (S) is poured, a parge coating (P) is placed on the outer surface of the body member (12) such that the parge coating (P) either binds to the outer surface or penetrates the body member (12) through a series of perforations on the body member (12) in order for the parge coating (P) to bind with the concrete of the slab (S) which has yet to set thereby producing a clean and solid finish of the outer surface of the slab (S) at the transition area. The body member ( 12) may have either a rectangular profile (1 12), a keyhole profile (214) or may have the perforations (20) on a series of inwardly directed deformations (18).</p> |
