Monolithic domes are constructed by laying a concrete ring foundation, inflating an airform, coating its interior with three inches of polyurethane foam, attaching a gridwork of steel rebar, and covering the rebar and polyurethane with three inches of shotcrete, a sprayed concrete. The exterior is coated with paint, stucco, ceramic tile, polyurea, sprayed concrete, metal, or cultured stone. The result is an extremely strong, pest-proof, and well-insulated structure.
