Wanted to get some thoughts from anyone else that has run into Effloresence on a garage floor. My thoughts are…While pouring the concrete the person inadvertantly moved the barrier in this particular spot and now there is moisture intrusion of a minor nature but enough to cause discoloration and the formation of effloresence. There are no pipes that I can map out that run under this area. Home is 2002 built.
Any Comments on this???
