Your Slab Is Not Dry
Solid hardwood cups because the boards absorb vapour from underneath and curl. Glue-down products let go when moisture pressure builds under the adhesive. Laminate swells at the edges and the damage is permanent. The moisture test takes very little time and it tells us whether you need a barrier or a different product entirely. Anybody quoting a floor for a slab without asking about moisture is guessing with your money.
