COREtec® waterproof flooring offers unique and innovative visuals on a vinyl that enhances durability. The rigid core features special top/bottom layers for stability and is made from a high-density composition for extra rigidity, providing superior impact and dent resistance. Recommended for both commercial and residential use, and can be installed in high-moisture and high-traffic areas. Since COREtec is 100% waterproof, COREtec Pro Plus floors can be installed in wet areas and will never swell when exposed to water. COREtec will not expand or contract under normal conditions. Further, COREtec never needs expansion strips in large rooms. Each COREtec Pro Plus plank or tile has an attached cork underlayment for a quieter, warmer vinyl floor that is naturally resistant to odor causing mold and mildew.
