Valid points for your neck of tbe woods. The combination of site conditions here are rather unique in some regards and common in others. I'm convinced it's the remaining rh within the slab being just enough to stimulate the mildew smell but not enough to create mold or breakdown the adhesive in this isolated area of 200 sf out of the 4000 sf area. This case further justifies the need to test multiple areas per ASTM 2170.
