Solid hardwoods are typically 3/4" or 19mm thick, although some do come in 3/8" (10mm) or 5/16" (8mm) thicknesses. This type of hardwood flooring can be installed with a nail-down installation method over wood subfloors. This type of hardwood is also very susceptible to the effects of moisture and temperature, because hardwoods expand and contract with moisture and temperature changes in the atmosphere. Since hardwoods expand and contract in the width of the grain, this type of hardwood flooring is not recommended to be installed over a concrete slab, unless otherwise stated by the manufacturer. There are some instances where 3/8"-thick solid hardwood can be installed on a concrete slab.
