We love click lock engineered hardwood flooring so much it is the only type we sell!
Click lock engineered wood flooring can be installed over a variety of subfloors, such as concrete and often times both above and below grade. Plus, click lock engineered floors help conserve the cherished hardwood on top, by using an alternate species of wood for the middle and back layers.
These layers called plys are bonded together. The top layer is what you see like Oak, Maple, Hickory etc.
