Minimum slab thickness for residential building

The thickness of a concrete slab for a building depends on various factors, including the type of structure, load requirements, and local building codes. Generally:

1. One-Story Building: For residential structures, a common slab thickness is 4 inches (10 cm).

Commercial or industrial buildings might require thicker slabs.

2. Two-Story Building: Residential buildings often use a slab thickness of 4 to 5 inches (10 to 12 cm). Again, commercial or industrial structures may require thicker slabs.

Three-Story Building: For residential, 4 to 5 inches (10 to 12 cm) might be typical. Commercial buildings could necessitate thicker slabs, and structural engineering input is crucial.

4. Four-Story Building: As the height increases, so does the need for thicker slabs.

Residential might be 5 to 6 inches (12 to 15 cm), while commercial or industrial could require more.

5. Five-Story Building: For taller structures, slabs might range from 5 to 6 inches (12 to 15 cm) for residential and possibly more for commercial or industrial.
