What do you recommend for a crawl space vapor barrier?

Its surrounded by frost wall. Wood floor system 2' above. Will 6mil plastic do? How about fastening / sealing to concrete frost wall?

K. Greenblott,
You can use 6-mil poly, although a product like Tu-Tuf or even a 20-mil swimming pool liner will be tougher (which might matter if people visit the crawl space often).
