Snoonyb I really appreciate your taking the time to help here. I know you are taking valuable time and I appreciate it. The deck is about 13 ft sq and solid. I can walk on it w/o feeling any softness or flex. But you can feel the vibrations (not so much flex) as someone walks around. With...

I'm 6'5 over 300 lbs. I can make it move. Is it possible to make it rigid enough with an extra layer of 3/4 - or with 5/4s plywood? Or must we go to a more flexible membrane?

Thanks for the welcome and the opinion. Yes we have additional plans re drainage but given the site we won't fully dry out the crawlspace. Interior moisture has been bad enough that I would like a vapor barrier from below, but don't want to cause the joists and sub-floor to retain more...

We have a 100 year old camp in humid Northeast that is closed for the winter. We just replaced the floor joists and subfloor and put a 6 mil vapor barrier on the dirt in the minimally ventilated crawlspace (2-3 feet), but it can't be sealed to the stone foundation and there will still be a lot...
