ABSTRACT:
Multiple layers of polymer foam form structural concrete into a desired planar shape that retains a foam panel when flat or upright. The polymer foam has a planar shape and an exterior surface with multiple channels into the panel. The channels are generally wider at the bottom and narrower towards the top, preferably a trapezoidal shape. In use, the panel is placed flat within a forming frame, exterior surface upwards. Then concrete is poured upon the exterior surface and into the channels. The trapezoidal shape of the channel prevents removal of the panel from the concrete. The concrete panel can then be used flat or upright as specified for a construction project.
