vapor/moisture barrier necessary?
Hi Gevans17, thanks for taking the time to offer your help.
I'm planning on laying the Advantech over the insulayment that is already down & then nailing/stapling the Bamboo to the Advantech. The insulayment doesn't appear to be a moisture/vapor barrier, just a noise dampener, so I'm worried about moisture coming up from the concrete subfloor, going thru the insulayment & & either causing mold or warping the bamboo.
I know the concrete subfloor is above grade but I can't find information online about whether above grade concrete subflooring needs a vapor/moisture barrier or not.
Again, thanks for any help you can offer.
