Jack, Our experience (bad) has not been with poured ESD flooring, but with conductive tile. Whichever type of flooring your client chooses, it cannot be stressed enough that the concrete slab be below the maximum allowable moisture level specified by the flooring manufacturer. Do not accept responses from the contractor that "it's close enough". My understanding is that excessive moisture under poured flooring is much tougher to deal with than tile.

They have done a lot of review, and based on literature and salesment, have narrowed choices to an epoxy base or a carbon filled urethane base poured floor. There is significant cost difference between the two, and one has a longer projected life. Does anyone have any experience with either of these flooring materials (or other choices) that they would be willing to share either on the net or one-on-one regarding this subject?
