What is a good carpet and pad for a room with a concrete floor? The room is a sunken room (3 feet lower than that rest of house). The land under it sloped from nothing down to 8 feet, so it was filled with alot of large rocks and dirt until it was level. then the concrete was poured on top. This was done about 20 years ago. I don't know if underground moisture would be a problem since it is not part of the regular ground.
