I have a promblem with the humidity in the summer and it sure does draw alot of moisture up through my floors. I also have poor ventaltion. We have built a basement with the intentions on biulding a house on top. 2 years later we still havent got the house built on top. Right know we are living in a basement home.Are concrete floor only gets wet when the humidity is high. I would really like some info. Every one that i talked to has pretty much said tough.
