<p>ROGERS, BERESKIN /A PARR TITLE: IMPROVED METHOD FOR ROCK REPRODUCTION INVENTOR: PHILIP DI GIACOMO This invention relates to improvements in methods for reproducing natural rock surfaces which are used as decorative faces for walls, facings, shorelines and the like. A rock surface to be reproduced is coated with latex and the latex is then coated with urethane resin to form a mold panel. The mold panel is removed from the rock surface and its inside is coated with a thin layer of sprayed concrete to form a concrete rock panel. The rock panel is removed from the mold panel and is used to form a cast-in-place reproduced rock wall. Tha concrete rock panel so formed is of sufficient strength to maintain its proper profile while concrete is poured behind it. Because of the concrete rock panels strength and rigidity, it can be readily supported in place by a simple framework. In the case of larger surfaces mold panels can be made of various portions of the natural rock surface, and trimmed along natural panels formed from the mold panels can be overlapped and the edges grouted together to reproduce the entire natural rock surface. The joins are substantially invisible since they occur along the fissures.</p> |
