I have a 9 year old tri-level. The other day it was 97% humidity and the garage flooring was a mess, as was all of the neighbors.....wet, dark and ugly. Well when we went downstairs in the evening, the basement carpet was wet in selected areas, nothing next to a wall or piping. We pulled the carpet away and found nothing......no puddle, just a soggy matting......no pipe broke, just regular cracks in the cement. What treatment should i do before putting down the new mat and relaying the carpet?
