The big and the best. Strong Built HD XL features detailed styles with an embossed grain pattern, and an enhanced four sided bevel for the look, feel and detail of real hardwood floors. A rigid core made from limestone and virgin PVC, results in a 100% waterproof floor that can be installed in wet areas and will never warp or swell when exposed to excessive moisture or large amounts of water. An attached pad underlayment results in a quieter, warmer vinyl floor that is naturally resistant to odor causing mold and mildew. Don’t pay more for less, Strong Built HD XL is the only waterproof vinyl plank for those who want the best flooring at no compromise.
