If you mean to join the vapor barrier at the seams, I believe it would work well. It can withstand the concrete/aggregate pour, and the stickiness is superior.... but I doubt 3M would "guarantee" the same vapor integrity as the vapor barrier material, as it is not specifically designed for that purpose. Then again, "there's nothing duct tape and bailing wire can't fix"! Lol ;)
The tape is thin. No more than 1 mil, if that.
Do not remember the temperature only know that it was COLD
