Cork is harvested from the bark of the cork oak tree, Quercus suber. As a material, cork consists mostly of suberin, a waxy substance that functions to prevent water from penetrating the cork tissue. Because of this property, cork in flooring provides resistance to water or moisture, and makes it possible for installation in places where other flooring types are not advisable.
