Well, about a year or so ago when ...believe it or not...somone was pouring a slab for the local city zoo. I was stunned. Plastic barrier in place ready to recieve mix. Then it had six mil plastic on top of the newly poured one as well! Not many of those around. Certainly not in the residential field.
Ok, that makes sense. All slabs should be constructed like this. They need a vapor retarder under them, then on top they should be wet cured for three days. After that the plastic is removed and the slab can begin drying.
This is how every slab I work on starts its life.
