Our combination of state-of-the-art CAD systems, high-tech equipment and technical plastering expertise provide us with all the assets to meet any need. Our focus is on supplying the best available element for any application. Our key people have been involved in the plastering and EPS business for a combined sixty years of experience. From the Fairmont Hotel in San Francisco, the R&D campuses in the Silicon Valley, the casinos of Las Vegas to the thousands of houses, which have added quality and value through architectural elements, have all benefited by our expertise to provide quality elements that work.

The wide range of coatings and finishes, which provide durability and beauty, are many and varied. Our foam is now being used to provide the look and durability of wood, concrete, gypsum plaster and stone. Every day we deliver another product that makes us proud of our abilities, and we strive to make you proud for choosing BayStone.


The only way to achieve high quality trim and detail work has been with inordinately expensive, slow and heavy stone or cast concrete moldings. There is now a superior alternative... Baystone.

Pre-Coated EPS

Expanded polystyrene (EPS) is a rigid, closed-cell insulation material that is white in color. It is a nontoxic material that provides Class 1 flame spread rating (25 or less) and is environmentally sound. Initially made from a petroleum byproduct, virtually all of our scrap is recycled into other post-consumer uses or back into the manufacture of other foam products.


Fiber Reinforced Plastic (FRP), Glass Fiber Reinforced Concrete (GFRC) and Glass Fiber Reinforced Gypsum (GFRG) offer superior performance in many situations. BayStone offers a full line of custom shapes to meet any need.
