COREtec is a great alternative to glue down LVT, solid locking LVT, or laminate flooring. The patented construction of COREtec features our innovative COREtec core structure, which is an extruded core made from recycled wood and bamboo dust, limestone, and virgin PVC. Since COREtec is 100% waterproof, COREtec floors can be installed in wet areas and will never swell when exposed to water. COREtec is inert and dimensionally stable; it will not expand or contract under normal conditions. Further, COREtec never needs expansion strips in large rooms.
