RH in Concrete for Wood Floor with Vapor Membrane
I am looking for advise on establishing a RH for a wood floor system. (special system from Europe very dimensionally stable)

The flooring has a RH limit of 90% over 6-mil poly that has a perm of 0.06.

I want to put the flooring down over 15-mil poly with a perm of 0.018-0.01. (83% less)

What RH should the concrete be? perhaps 83% of the difference between 90 & 100? So that would be 98% rH? I don't think it is a sliding linear scale though.
