Under-slab vapor barrier
The project I am working on has a 10 mil vapor barrier spec'd. It has come to my attention that standard 10 mil poly from the supply yard is not technically rated for under ground use as the content of the plastic may contain recycled material that will not hold up over time. A product such WR Meadows Perminator (http://www.wrmeadows.com/perminator-underslab-vapor-barrier-retarder/) should be used (there are others out there). What do you think?
Secondly, does anyone have experience with Grace PrePrufe 300 self adhering under slab waterproofing?
Thanks for any feedback
