What is the min thickness of slab

Question

Accepted Answer

The minimum thickness of a slab depends on various factors such as the load it needs to support, the type of material used, and the span of the slab.

The minimum thickness of a slab is typically determined by structural engineers during the design phase.
The thickness of a slab can vary based on the intended use of the structure and the local building codes.
For residential buildings, the minimum slab thickness is often around 4 inches (10 centimeters).
In commercial or industrial buildings, the minimum slab thickness can range from 6 to 8 inches (15 to 20 centimeters) or more, depending on the expected loads.
Factors such as the type of soil, reinforcement requirements, and the presence of any additional loads (such as heavy machinery) also influence the minimum slab thickness.
