How are the replica boulders made and shipped?
Molds for the reproduction boulders are meticulously taken from actual rocks found in nature so our customers are guaranteed a finished product that looks and feels like the real thing…even from inches away. The latest technology is then used to spray an industrial-grade, UV-protected 98% “closed-cell” structural polyurethane composite–the same material used for high-impact bumpers in the automotive industry and a variety of other common product–into the castings to capture the original surface detail and to create rugged, hollow replicas that are open at the bottom and approx. 2-3 inches thick. Our faux rocks won’t chip, crack, break or wear down due to the elements. Because they’re made from a 98% closed-cell polyurethane, they are waterproof. They have a high R-4.5 per-inch-of-thickness insulation value (also beneficial for noise-reduction of motors), are extremely impact resistant and are one of the most durable products on the market today. The rocks weigh between 15-60 lbs. d
