Minimum 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 determined by the structural engineer based on the design requirements and load calculations.
For residential buildings, the minimum slab thickness is typically around 4 inches (10 cm) for interior slabs and 6 inches (15 cm) for exterior slabs.
In commercial and industrial buildings, the minimum slab thickness can vary depending on the intended use and load requirements. It can range from 6 inches (15 cm) to several feet.
Factors such as the type of material used (concrete, steel, etc.), reinforcement requirements, and the span of the slab also influence the minimum thickness.
For example, a slab supporting heavy equipment or vehicles may require a thicker minimum thickness to ensure structural stability.
It is important to consult the structural engineer or refer to the building codes and standards applicable in the specific region to determine the minimum thickness of a slab.
