Can anyone recommend a vapor barrier for use under a cement floor?
I live in an area that is close to an EPA superfund site. I am aware of a toxic plume of underground water that is close by. I am concerned that these voc's can permeate the cement floor and foundation. We are going to pour cement on top of an existing basement floor which shows white deposits on it. Is there some type of vapor barrier that can be placed under the newly poured cement. Our contractor tells us that thinset is non porous. Is that true?
