A wall or panel has a thin concrete layer with a cross-sectional contour having protrusions and indentations forming other objects, such as stone work, brick or wood. A reinforcement layer may be affixed to the concrete layer to provide tensile strength and impact resistance to the concrete layer. A foam layer is affixed to the reinforcement layer to further reinforce the concrete layer, and so that the wall or panel is light weight. A second concrete layer or a rigid backing layer may be disposed opposite the concrete layer so that the foam is disposed therebetween. A method for forming the wall or panel includes spraying the concrete onto a mold surface which has indentations and protrusions for forming the other objects. The reinforcement layer is sprayed onto the cured concrete layer. The mold is closed and foam is introduced into the mold.

1. A method for forming a panel, comprising the steps of:a) providing a mold having an inner mold surface with macro indentations and macro protrusions; b) applying a wet mixture of concrete material to the inner mold surface of the mold to form a concrete layer including a cross-sectional contour corresponding to the indentations and protrusions of the inner mold surface; c) curing the concrete material until dry; d) applying a layer of elastomer material to the concrete layer to form an elastomer layer secured to the concrete layer; e) introducing foam into the mold to form a foam layer secured to the elastomer layer; and f) removing the secured concrete, elastomer, and foam layers from the mold.
