Installing a crawl space moisture barrier / vapor barrier is the best way to keep harmful moisture from evaporating into the floor system and into interior walls underneath your home. Evaporation Moisture that is allowed to condensate is conducive to mold, rot wood, rust pipes, termites and other unwanted pests. To keep moisture from condensing, all you need is a crawl space moisture barruer under your home.
Crawl space Moisture Barriers / Vapor barriers will only deal with ground evaporation moisture not humidity condensation, water intrusion, leaks – these area other moisture issues that also may need to be addressed.

North Carolina Building Code for a Moisture Barrier:
R408.2 Ground vapor retarder.Aminimum 6-mil (0.15 mm) polyethylene vapor retarder or equivalent shall be installed to nominally cover all exposed earth in the crawl space, with joints lapped not less than 12 inches. Where there is no evidence that the groundwater table can rise to within 6 inches (152 mm) of the floor of the crawl space, it is acceptable to puncture the ground vapor retarder at low spots to prevent
water puddles from forming on top of the vapor retarder due to condensation. Install a drain to daylight or sump pump at each low spot. Crawl space drains shall be kept separate from roof gutter drain systems and foundation perimeter drains.
