RH Numbers Rising

[CC Solutions]

It has been my experience that the vapor retarder moves with the slab. I'm sure that there are no absolutes, so I won't say it always does, and in those cases, yes there would be a transportation medium available for moisture to move laterally.

I think I should just put a Koester MMS on every slab and the world would have no more worries!

I've worked in Washington, Seattle to be exact, and actually enjoyed many sunny days (lucky me ) Beautiful country out there! Vapor retarders must be on direct contact with the slab, and with all the rain it is hard to dry anything out before a roof is on and the windows are installed. Even then you have hundreds of workers tracking water in with boots in the main hallways.

I always seek out the coffee shops in Seattle.... They have fantastic coffee and seafood. Anybody have a moisture issue in Seattle that maybe needs me to take a look at??
