The Coretec Pro Plus Enhanced Lyric Oak Luxury Vinyl Collection features enhanced painted bevels for ultra-realistic wood and stone looks, as well as a rigid core construction. These features make this collection suitable for both residential and commercial use and can be installed in high-traffic and high-moisture areas. Constructed from a high-density composition with special top and bottom layers for added stability, the rigid core provides superior impact and dent resistance. The patented COREtec technology makes them 100% waterproof. They can be installed in wet areas and will never swell when exposed to water. All COREtec floors are dimensionally stable, and will not expand or contract due to temperature or humidity under normal conditions. Plus, COREtec never needs expansion strips in large rooms. Each COREtec Pro Plus Enhanced plank or tile has an attached cork underlayment for a quieter, warmer floor that is naturally resistant to mold and mildew that can cause odors.
