Quartz (aka Engineered Stone) is a composite material made of crushed stone bound together by a polymer resin. Typically less porous than natural stone, it is more resistant to mold and mildew… making it a great choice for kitchen countertops or vanity tops. We offer some of the most popular brands of engineered stone including Cambria, Silestone, and Viatera. (Note: Quartz slabs available in CT only.)
