Can you change a crawl space into a slab?

How can I dry my crawl space faster?
Warm, moving air picks up moisture more readily. To speed up the drying process, place a source of low heat, such as a light bulb, inside the crawl space and position one or more electric fans where they’ll blow air across damp surfaces.
