COREtec Plus is a great alternative to glue down LVT, solid locking LVT, or laminate flooring. The patent-pending* construction of COREtec Plus features our innovative COREtec core structure, which is an extruded core made from recycled wood and bamboo dust, limestone, and virgin PVC. Since COREtec Plus is 100% waterproof, COREtec Plus floors can be installed in wet areas and will never swell when exposed to water.
