A combined slab and foundation/footing is called a ___.

• A. Joint slab
• B. Monolithic slab
• C. Slab-on-grade
• D. Raft slab

Answer: (A)

A monolithic slab is a single concrete pour that forms both the floor slab and the footing in one piece. In this setup, the edge of the slab is thickened to act as a footing, providing the foundation for the structure without separate footings poured later. This approach reduces joints and can simplify construction. Slab-on-grade refers to a slab poured directly on the ground, typically without a thickened edge acting as a separate footing. A raft slab is a large, thick slab that distributes loads over weak soil and acts as the foundation for a building, not a simple combined slab and footing. A joint slab isn’t a standard term for a combined slab and foundation. Therefore, the correct term is monolithic slab.
