An interior mold form is disclosed, which creates arch-shaped hollows inside a cast material. The form may be used to cast the material into structures as strong as solid structures, but having less weight. More efficient use of material saves on material costs. The mold form creates arch-like hollows in two perpendicular directions within the material, to provide strength against stresses in multiple directions. A process of casting, using the mold is described. An exemplary mold formed of polystyrene is applied to concrete casting. Structures, including those cast of concrete, using the mold and process are also disclosed.
