Question
QUESTION: Hi I was woundering if you pour on refractery cement like thay do in garages for extra space can you do the same without a shell.so from outside its just a cement parking lot?

ANSWER: Hi lamar, I'm a little confused by your question.  Basically, if you are using a concrete slab for parking and have living space below, you need to have a complete moisture repelling system in place.  Otherwise water will penetrate the concrete and drip into the living space.  I hope  this information helps please feel free to write again sincerely bruce e johnson..bejohnsonconsulting.com

QUESTION: I have seen the condensation in them rooms before what do you do for the moisture barrier. and was thinking about the strength and will it crack like most parking lots?

Answer
Hi again lamar, the vapor barrier would be similar to an asphalt roof so that it can't leak even if the concrete cracks.  Concrete cracks.  It is the nature of the beast.  If you have enough expansion joints in it you can decrease the chances of actual cracking but you will have to waterproof the joints.
