Bill,
I agree with you about the tiles. In some places they would not be the best. I had two professioonal floor companies come in and do my garage with the 2 part epoxy and all the prep work. One time it lasted about 2 years. The 2nd company told me the first one did it wrong and they did it right and charged me twice as much. Theirs lasted almost 3 1/2 years and I had spent enough on those two floors to build a garage twice the size of mine. So in my case, the tiles have been a great thing as we don't have a lot of snow around here, but do have tons of rain. But as I said, in a humid and damp area I don't think they would be as good as the epoxy, and especially if you don't have to have it done over every two or three years. I am in no way pushing the tiles over the Epoxy or the other way around. I would have had an Epoxy floor if they could have made one last. I haven't had a problem since I put in the tiles and I can take them out easily if I want to.
