Hi Pdayton,

You may install Shaw engineered flooring over a concrete sub floor. Below I have included Shaw's installation
instructions for concrete sub floor installation:

Concrete Sub floor Guidelines

Concrete slabs should be of high compressive strength and constructed to prevent groundwater from permeating the concrete. Engineered hardwood flooring can be installed on, above, or below-grade. In addition, it can be installed over above-ground, suspended concrete floors. The suspended concrete must be a minimum of 1 1/2 inches thick and must be structurally sound.

The exception to this is lightweight concrete (which usually contains high amounts of gypsum) having a density of 100 pounds or less per cubic foot. Test for lightweight concrete by using a nail to scratch the surface of the concrete. If the concrete crumbles or turns to powder, it is not sound and you should NOT install the hardwood flooring. Use the floating installation method (products 3” or wider) only for lightweight concrete sub floors.
