|In response to Re: NEED WET CRAWL SPACE INFO????|
What you are referring to is vapor barrier material that prevents water vapor from damaging the structural building materials. If the crawl space gets soaking wet with 1 to 2 inches of water and then drains away, the vapor is still being released into the crawl space and soaks into the floor joists and the insulation, and into the sub floor. In time it will create mold, mildew, and dry rot.
Go under the crawl space and staple new polyvinyl vapor barrier to the bottoms of the floor joists and if the vapor barrier sags between joists, also staple lath (a lighter type of wood) across the floor joists to help support the vapor barrier. It would be better to do this after a month or two of warm dry air to relieve the moisture that is already in the insulation, before you trap it there with vapor barrier.
: I had an addition built on my home -16' X 18'-after several very soaking rains, it will get 1 to 2" water - it will go away in a day -
