Vapor Barrier

6-mil vapor barriers are the standard for a new crawl space or to sell a home. However, they are not effective in protecting the crawl space from the earth's moisture. 6-mils are fragile, they rip easily, and typically have a slick coating that does not allow seams to be taped and sealed. They cannot be wrapped or adhered to walls and piers because they will rip right off the walls and are installed using U shaped stakes creating more holes in the system and more weak points.
