Thinking about using a technique/treatment called Neutocrete or something similar to seal the crawlspace on a new house we’re building. Instead of using traditional venting, the crawlspace would basically be a short basement. Any ideas on how to condition/control humidity in this area? I’m not a builder, just a future homeowner, to give you my perspective. Would it be as easy as running ductwork to the space, just as the rest of the house? Or would a crawlspace dehumidifier be a better idea? We are in southeast Georgia. And what are the usual codes about putting lighting in a crawlspace? Thanks.

you need to make sure that you seal it very well with a15 mil or better . over lap at least 12" on seams and glue everything to walls and pilers. then you can use a dehumidifier (which i plan to use) or put about 2 vents in but no return. Remember to vent for radon underneath. the epa web site has some good stuff. I ordered my liner from your crawl space.com 20 mil reinforced, was about 35 cents a foot.
Check out Tu-Tuff for the liner. I used it over dirt in my crawl - sealed it to walls etc.- opened one vent and am extremely pleased with the results. No dehumidifier needed..
Have you run this by the building inspector to make sure they will allow it? they can be touchy about venting crawlspaces, which is really a stupid idea, but you can just cover up the vents after they leave.
Either way, you might want to get a feel for the opinion of the local inspector first.
