A vapor barrier will protect your floor from moisture coming up through your concrete. If you have concerns about too much moisture coming from below, we recommend either sealing your concrete with GBS Penetrating Concrete Sealer or using Quiet Walk Plus as your underlayment, which wicks out moisture as it arises.If you are concerned about moisture coming from above your floor, this is virtually a non-issue provided you clean up spills as they happen. If your space is prone to a lot of moisture (flooding, dishwasher exploding often, overflowing sinks and bathtubs, etc.) then we would recommend you go with glue down floors that can handle high moisture, such as Amorim Waterproof Cork Flooring or Forbo Marmoleum Sheet Goods https://www.greenbuildingsupply.com/All-Products/Sheet
