"... I purchased this product because it had the most realistic look and the ease of installation. The panels are light weight and can be easily cut to size. I've installed cultured stone many times and GenStone is by far is much easier to use. I would recommend this product to anyone looking to install cultured stone."
~ Walter – Reading, MA

“Choosing MoistureShield® was the best decision ever. Walking onto our porch we had a area that always stayed slippery. No matter how many times we bleached and cleaned it nothing worked until we used MoistureShield®. It's now safe to walk on when it's wet.”
~ Ada Miller
