Floors, walls at substructure level and basements are at the interface between the ground under the building and the building interior.
Basic functional requirements are to be structurally sound and to provide a waterproof barrier between the ‘wet’ supporting ground and the dry interior of the building. Generally waterproofing barriers come in three forms.

In addition structures below the ground may also need to withstand the horizontal pressure of the soil and sometimes water. In such situations the structure acts as a retaining wall.
At ground level, floors and their surrounding structures not only need to stop moisture entering the building and support the surrounding soil, but like foundations the floors need to be stable. Floors need to be able to support all applied loads without settlement.
