Creating a vapor barrier in a basement
May 28, 2017 6:00 AM - Q. My wife and I are in the planning stages of finishing off half of our basement into a couple of bedrooms, and a small living/TV room. I am concerned about water and water vapor creating that mildewy basement smell once all of the construction is complete. To that end, before we start I am addressing any water entry into the basement, to which I believe I have been successful.
