ObeX11 America's Only 6 Mil Vapor/Moisture Barrier Plastic Sheeting with Termite Control (4' W x 200' L)

I used it to lie as barrier in the crawlspace. I have not checked this part of the house and when mold started to appear in parts of the house, we discovered the physical and emotional damage this has caused. We cleared all the mold, let it dry, then place ObeX11 6mil Vapor/Moisture Barrier Plastic over the ground. We also insulated under the floor with radiant barrier, also purchased at Amazon, so the whole crawlspace looks encapsulated, clean and healthy for the house. My son did all the work and is impressed with the quality of the plastic ---great product!

I have it down and everything seems to be ok. Time will tell. It was easy to work with in the 4 foot wide rolls.
