Usually the first 4 letter word out of your mouth Ernesto is- TEST. I'm surprised you didn't mention it here. I'm not an advocate of extensive testing, I'm a 'seal it and forget it' guy. That is when it's being done professionally and according to specs.

I believe some technical people decided that a chimney effect was created by covering the slab, forcing the MVE to the perimeter. Usually the 6mil (8mil in the case of the now defunct wilsonart) stopped short of going edge to the edge causing the floor to absorb moisture though the exposed core cut edge. I remember when wilsonart's specs included coating each cut edge with their adhesive/sealer.

In this case and in most involving Allure flooring is that it is chosen for economic reasons though basement floors usually require extra attention, at least more consideration. I think I'd find out if I actually have a MVE problem before I decide how to proceed.

I recently installed about 800 sf on grade concrete.
