I've used stall mats for my home gym, which leaves some area to breathe underneath the 3/4" mat by little circle risers. Due to the humidity and concrete sweating, how would these do with water pooling underneath? Can you also compare your product to the stall mats? Thanks.

Our 3/4" Extreme Mats would be the same as the stall mats that you have now. If you have any moisture coming up from your subfloor, there would be potential for water to pool under the mats. This won't affect the mats in any way, but you may notice when pulling up the mats that there may be a white film under the mats. This film is not toxic and is not mold; it is actually salt from the concrete that has collected and dried on the mat. This salt is very easy to clean off the mat with a mild soap and water solution.
