Thickness of concrete slab depends on loads and size of the slab. In general, 6 inch (150mm) slab thickness is considered for residential and commercial buildings with reinforcement details as per design. Methods used for finding slab thickness varies for different types of slabs.
Q. How do you design a concrete pad?
Q. What is the minimum depth for a concrete slab?
As a rule of thumb, concrete slabs supporting lighter weights such as paths, patios and shed bases will need to be 75-100mm thick, while driveways and garages need to be at least 100mm thick. Slabs intended for commercial use should be at least 175mm thick and reinforced.
Q. Why do footings have to be below the frost line?
When you excavate your footings you will need to dig below the frost line. This is the depth at which the moisture present in the soil is expected to freeze. Once your footings are buried below the frost line the ground will act as a barrier to insulate the soil below the footing from freezing in the winter.

Q. Which slab is used for residential building?
The concrete slab is a horizontal surface of a residential building or commercial building, factories, flat, etc. The thickness of the steel-reinforced slab is near about 100-500mm. This types of slabs are used for ceiling and floor purpose.
Step 1: Preliminary Design. Find depth of slab using deflection control criteria. Take span/d = 28 for simply supported slab and 32 for continuous slab. D ≥ D min = 100mm for normal design and 125mm for earthquake resistant design. Step 2: Analysis of Slab. Slab is analyzed by IS code method.
Q. What is concrete slab thickness suitable for residential use?
Pour concrete mix over the compacted gravel base. Screed the concrete with a straight 2-by-4 so it is level with the forms. Fill in any holes and low spots as you screed. Tap on the sides of the form walls to help work any air bubbles out of the concrete.
