What is Quartz Flooring? Quartz flooring is an all natural flooring solution comprised of a combination of quartz sand and calcium carbonate. As one Earth’s hardest materials it is virtually indestructible. Quartz is a perfect flooring solution for commercial spaces that receive heavy traffic and excessive daily wear and tear. These floors typically have a non-slip finish and are suitable for pool decks, bathrooms, food processing facilities, and often spec’d in commercial grade kitchens.
