Vandervort admires Squak Mountain Stone for its good looks and “upcycling” attributes. Made from low-carbon cement, recycled paper, recycled glass, and coal flyash, the material “resembles soapstone or limestone,” he says, “and provides a beautiful alternative to concrete.” Slabs come in five colors and measure 56 inches wide, 96 inches long, and 1 3/8 inches thick.
