Abstract: A concrete structure system formed of pre-cast concrete may form a wall having a decorative surface treatment. The structure system may include a column portion and a panel portion. The column portion may include a slot for receiving a panel portion of an adjacent structure. The column portion may also include an opening for receiving a substantially rigid member for supporting the column portion in an upright position. The substantially rigid member may be embedded in or attached to a footing for supporting the structure. Various different techniques for attaching the substantially rigid member and/or column portion to the footing are disclosed.

Abstract: An apparatus for producing one or more pre-cast concrete structures. The apparatus may include partitions that may be positioned in a side by side arrangement. The partitions may be moveable with respect to each other to facilitate installation of reinforcing material and removal of the concrete structures from the apparatus after the concrete has hardened. Cavities may be defined by the partitions for receiving concrete to form structures having panels with integral columns. The columns may include slots for receiving an adjacent panel such that adjacent concrete structures may be joined together to form a continuous wall. The partitions may also include interchangeable liners such that different textures or finishes may be applied to the concrete structures.

Abstract: 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.
