Engineered hardwood is strongly preferred over solid hardwood for Austin homes because its cross-ply core resists moisture-related expansion and it can be installed directly over concrete slabs. Solid hardwood is highly vulnerable to cupping and gapping on concrete without a built-up subfloor and strict HVAC management maintaining 35-55% relative humidity.
In Central Texas, where concrete slab foundations are the norm for homes built after 1980 and indoor-outdoor humidity swings can range from 30% to over 80%, solid hardwood is highly vulnerable to cupping and gapping without a built-up subfloor and strict HVAC management. Engineered hardwood is strongly preferred for Austin homes as its cross-ply core resists moisture-related expansion and it can be glued or floated directly over concrete slabs.
