How thick is slab on grade foundation?
4-inches
Concrete floor slabs-on-grade shall be cast over two layers of 2-inch sand fill with a minimum 6-mil moisture barrier membrane sandwiched between the two 2-inch-layers. The slab shall be at least 4-inches-thick and shall be reinforced with #4-bar at 16 inches on center each way.
Can I pour a 3 inch concrete slab?
Here, pouring a concrete slab 4 inches in thickness is fine. A 3- to 4-inch slab will work for the floor of a storage or tool shed, workshop, garden shed, or playhouse.

So, the “4,000 PSI” rating is for the standard 4-inch thickness of a residential concrete slab. This means that a 3-inch slab will be slightly weaker, while a 5-inch slab will be slightly stronger, in terms of compressive strength. Tensile strength is a bit harder to measure.
Which is concrete grade used in slab on grade?
The grade M25 grade concrete has a compressive strength of 25n/mm2 within 28days of curing. M25 grade concrete gets also used as an RCC, the Reinforced cement concrete. M25 is used majorly during the construction of slabs, columns, footing, or beams.
