you’re a riot. Why do they put visqueen under concrete?
To prevent migration of moisture from the ground into the slab which can cause surface moisture to appear on the slab during the dozen or so days a year in south Louisiana when the temperature of the slab is above the dew point of the ambient air and the relative humidity is below 40%. The rest of the year surface moisture on a slab is the result of the condensation that occurs when the slab's temperature is below the dew point of the moisture laden air.
