Some engineered wood flooring products are designed for a glue down application when installing flooring over a concrete slab.
That being said all wood flooring is a natural product and will move with varying moisture and humidity levels and solid wood flooring will move more than engineered because it is not stabilized by alternating directional layers.
As a result it will reduce moisture vapor transmission through concrete.
Other products are better suited for a nail down installation where they are secured to a wood subfloor with nails or staples.
