ABSTRACT:
Apparatus and method for the fabrication of semi-flexible artificial rock sheathing; a one-coat silicone elastomer is brushed or sprayed upon the surface of a substantially flat natural rock formation to form a mold that is adhered to a wood-framed fiberglass cradle that hold the shape of the mold; when removed from the rock formation, the mold is sprayed with a thermoplastic elastomer to form a semi-flexible rock sheathing having the same characteristics as the natural rock surface from which the mold was formed; after the materials are fully cured, the sheathing sheet may be separated from the mold and used for the fabrication of rock, rock structures, by attaching sheathing sheets to the exterior of a framework, followed by cutting and forming different shapes.
