Moisture barrier padding on concrete basement floor

A couple of years ago we built a bedroom in our basement. When we purchased the carpet from Home Depot the salesman adviced us to get 1/2 carpet padding with a moisture barrier. A couple of weeks ago our sub pump failed and we had a flood. All of the padding had to be removed and the carpet has to be replaced. When we told the company that is fixing the room and replacing the carpet that we wanted the same moisture barrier padding the guy told us that he would not recommend putting carpet padding with a moisture barrier on a basement floor because it will cause mold to grow. We have recently found that not everything that he has told us has been true with some other dealings in regards to the room and are concerned that he may just be trying to cut corners to make more money off of our insurance company. The insurance company is willing to pay for the same type of pad with the moisture barrier that we originally had. Can someone please tell me if it is true that carpet padding with a moisture barrier installed on a concrete basement floor will cause mold to grow underneath? The concrete has been painted with the appropriate paint for a basement floor. Thank you for your time.

Carpet padding on a basement floor is NEVER a good idea. Like said it will hold moisture and grow mold. Also if there was no pad and it got wet with just gray water it good be steam cleaned in place to save the carpet.

Ditto airman. The general rule is to assume that basements floors and walls let moisture into the house via water vapor diffusion or liquid if an outright leak. Good practice is to build so that the water can dry to the interior, which means materials need to breathe. No moisture barriers.
