Abstract
An apparatus for molding dry cast products having a textured side surface is disclosed. The apparatus comprises an open compartment for receiving a dry concrete mixture and a plurality of walls laterally enclosing the compartment. At least one of the walls has a multilevel surface with a plurality of sections in an overhanging relationship with each other and transitional curvilinear steps bridging adjacent one of the sections to impart a textured side surface resembling a natural rockface and allowing stripping of the dry cast products from an open bottom side of the compartment.
