building foundation is the base of any building which receive load from the building, resist it and transfer it to the subsoil. substructure is the structure below the ground floor bed including the ground floor bed. substructure composes of foundation, basement and ground floor bed.
It all depends on the ground conditions and the load of the building. The is also a little confusion around your terminology as the term 'foundation slab' is legitimate. Maybe you are referring to strip foundation versus raft foundation. There are also basement foundations which will help stiffen the construction of a building and anchor it into the ground.
One or more floor of a building that are completely below the ground floor is basement. A floor of a building that is half below ground, rather than entirely such as a basement is semi basement.
A basement is a substructure or foundation of a building, or, the word can also refer to the lowest story of a building, usually below ground level. Breaking the word down into the two parts of "base" and "-ment" explains why the word is used to describe those things. "Base" refers to the Lowest or bottom part of something and "-ment" as a suffix in this context means result, object, or agent of an action. So a basement is the resulting object of building the foundation or base of the home or structure.

this is because when the area of contact between the ground and the building increases the pressure exerted by the building will be less for the same force.
