Gravel will serve only to mask the moisture in a crawl space, rather than to eliminate it. Once you have eliminated the moisture problem using plastic, sand will stay dry and also serve as an insulator between the dirt floor and the crawl space.
Homeowners use plastic to cover their crawl spaces to control moisture and create a barrier against vapor. Without such a barrier, condensation can infiltrate your home’s walls and insulation, creating a substantial risk of mold and mildew. Plastic sheeting can also help turn a crawl space into a usable storage area.
Where moisture is a known problem, vapor barriers are integrated into wall, ceiling, and floor construction to combat the effects. But nowhere is moisture more damaging than in a crawl space, even though it is not seen. Because the crawl space has direct contact with the ground, it should be no surprise that moisture can develop here.
The best materials for a crawl space floor are gravel, crushed stone or concrete, with the best of those choices being concrete. Concrete will keep out moisture and bugs. Construction work that might need to be done in the crawl space will be much easier with a finished concrete floor.
