What is a characteristic of a suspended slab?

A suspended slab is characterized by its structural configuration, where the foundation wall and the floor are distinct elements that do not sit directly on the ground. This separation allows for various advantageous features, such as better drainage, reduced moisture issues, and the potential for utility lines to run beneath the slab. This design is particularly beneficial in areas where soil conditions may be unstable or where flooding could be a concern.

In contrast, a slab that is laid directly on the ground is referred to as a "slab-on-grade" and does not share this separation from the foundation walls. Integrated insulation typically applies to certain types of construction but is not a universal characteristic of suspended slabs. While suspended slabs can be utilized in commercial buildings, they are not exclusive to this type of construction; hence, this option is broader than the distinct definition of a suspended slab.
