Taking a poll about crawl space vapor barriers

[square1]

The Pro's do plastic over sand

Your knees will thank you if you use sand, gravel is a killer. My preference would be the vapor barrier laid down, then followed by a thin layer of concrete, even just 2" would make for so much nicer and easier access over the years.

I usually put sand in crawspaces. Gravel isn’t fun to crawl on.

Nor is the chunks of mortar and block or brick that the masons leave behind.
