It is not recommended to install solid wood flooring over a concrete slab. Although this is the general rule, there have been successful installations of solid wood flooring installed over dry, concrete slabs. This entails several additional steps. A plastic barrier is set over the slab and taped at all seams. Then some sort of moisture-resistant wood subfloor (marine plywood) is built on top of the plastic film. Then the flooring is nailed to the wood subfloor. If you decide to take the chance be sure to consult with the manufacturer as to their recommendations. Be aware, you may be voiding your warranty. There is a new synthetic underlayment product on the market (called Sika AcouBond) that may allow for installing solid wood flooring over a dry slab. Check with the manufacturer of the wood floor to see if they will warranty this type of installation and what their recommended installation procedures are for this type of installation.
