A typical foundation may have at least one vent (usually a screened opening) per side and a single access door. The foundation floor can be dirt, poured concrete, or dirt because of this covered with a moisture barrier; the last two options are more desirable. Mid-span support is often necessary floor joists that span between walls, and this is generally provided by posts that rest on concrete piers or footings.
