I live in the desert and seen slabs so dry without a vapor retarder underneath it virtually sucks the moisture out of patch right before your eyes. I've seen them so wet you can smell it like a wet dungeon when you walk in.
You just need to know your concrete and know how to check it.
Heating up a slab for drying increases curl and later relaxation, causes movement at the joints. There is no cure for nautral drying, no matter how you accellerate the drying there are consequences.
Don't be silly. There's a plethora of alkaline resistant adhesives out there.
Why is it the contractors who live in arid climates believe they do not need a vapor retarder? The desert is by far the worst area for vapor emissions! If you look at what drives moisture emissions, temperature and humidity. The higher the temperature and the lower the humidity (the desert) the faster the moisture flow. I deal with moisture related problems in both Phoenix and Seattle and Phoenix is by far the worst. Sorry Stephen, but Tuscon is the worst in the US.
