We have a split-level house. Lower level is all concrete. 1/2 of that concrete lower level, is covered with pad and carpet. The remaining 1/2 is exposed concrete floor (garage, laundry room & storage room). Part of the 1/2 that is covered with pad & carpet, we use as our home office. This carpet over concrete office is a room 13' X 20'. The carpet in this room is more than 25 years old! We want to replace the carpet with a new hard surface flooring. My wife likes the idea of vinyl planking/tile. However, when I did research in to vinyl planking/tile, there are warnings against ---"rolling things across it." ...Since I would like to feel free about rolling wheeled office chairs from place to place, in the office, I worry about heavy usage and vinyl (e.g. moving chairs). Also, some vinyl manufactures warn against women walking across the floor with spiked heeled shoes! Which leads me to question if this is the right flooring for a heavy use office area. --I was thinking of regular 3/4" oak floor (tuff stuff). ---My wife counters with concerns about the cement floor moving and the possibility of moisture under any oak that we might install. Ok, I need some thoughts and recommendations. Any help would be most appreciated. ---Jaes.
