Jazzee,
I have had no problem at all with the tiles and moisture. The gap they leave with the honey comb under them is not air tight and moisture can escape. In fact, shortly after I installed mine I ran the washing machine over while I was gone. When I came home I had water and soap suds about half way across the garage. I just wiped the top off and thought I will wait a couple of days as it is hot and see what happens to the water that went through the seams. About a week later I took up the line of tiles closest to the washing machine and there was a little water left, but most of it was gone. So while I had the tiles up I just took a rag and wiped the little that was left up. And out about 2 feet out from the machine it was already dry. I am sure that the weather and humidity will cause a difference in the way this would have dried as it was quite hot here at the time.
