We had a dirt crawlspace about 4 foot high with some gravel on top. No water problem. We recently had drain tile and a sump installed, and had a concrete floor pumped in. There was a vapor barrier laid down under the concrete before it was poured. Now, we are experiencing alot of condensation on the duct work running in the crawl, and it is forming large but shallow puddles on the floor. I know this isnt necessarily bad for the concrete, but we feel that the water laying there will evaporate and maybe start to mold or mildew the wood floor above. Any thoughts or suggestions? Thanks
