New concrete in basement gets damp.
Ok so last summer I installed a french drain along the front wall of my basement. I already had a sump pump in the corner but I wanted to direct all the ground water from the other side of the house over to the pump. I didn't have any water problems until all of this rain. It was to be expected. But most of the system seems to be working fine except about a 2-3 foot area in the middle of the house where the concrete was the thickest. The problem is that the new concrete that I put in over the pipe and the stone is getting damp and it smells really bad and I bet will probably cause mold eventually. The rest of the old concrete in the basement is fine. Also noticed that the spots where they drilled for termite treatment get damp too. So is the original floor sealed with something that keeps it from getting damp? Should I seal the new concrete that I put in with something?
