Hi All, I have a crawl space that is roughly 10' x 10' square. Its got a dirt floor and is only about 3.5' tall without any ventilation. The walls are cinder-blocks and it gets real humid in there, I wanted to cement the floor but I wasn't sure if that was correct. I have read that I should put 6mil of plastic down and then some gravel over it, Ill post some pics of it tomorrow but I was wondering if it was better practice to just put a 2-3" layer of cement and call it a day. Any help would be greatly appreciated.
