摘要: A unitary assembly facilitates constructing concrete foundation pads made of poured concrete, the being useful to support a structure or building. The apparatus comprises existing planar forms connected by taper-shaped corners using wedge connectors define an upwardly-tapered cavity shaped hold until cures. is sufficiently rigid and are held at angle sufficient for self-release from cured without disassembly when lifted/moved vertically off concrete.
