I'm building a new house. yesterday they just poured the cemement flooring for my basement/garage. To my horor The crew did not put the 6" Poly under the cement where there Garage is (the garage is below living quarters). I looked at the plans and it did call for poly under the cement in the garage. My question is: Is there any REAL reason not to put poly under a cement slab that is in a garage? I'm considering making them rip/jack hammer it out and do it again (It was clearly in the plans). I of course do not want to do this so I'm wondering if the plans were over kill.
PS I live in a wet climate
my 2 cents...
if it was in plans it...shoulda been done.
what i can say about NOT having the ploy under G floor is, we`ve waterproofed quite a few walls/part wall-crack under a G floor and to this day, after 25+ years we have YET to see any poly, lol.
now, most of the G floors have been fine, no problems w/cement work is what i can tell ya.
where the poly, to me, is more helpful is under a basement floor, especially to help prevent radon gas....not that the poly is a solve-all by any means but, sure wouldn`t hurt. hopefully they poured bsmt floor 4" and didnt get cheap and pour 3" or less
