The footing directly transfers the loads from the column to the soil. The footings may be rectangular, square, or circular in shape. The footings which are provided under single columns are called isolated footings.
What are the steps for installing RCC footings?
Before installing the footing, ram the ground that was excavated for it. This increases the strength and stability of the soil.
After that, cover the area with 150 mm of concrete, creating a bed. This will give you a plain surface for your footing.
When fixing the reinforcement cage, make sure that its alignment is right.
Pour the concrete onto the cement bed after applying a layer of slurry to it. Make sure the amount of concrete used is based on the foundation size, and don't forget to do shuttering.
Last but not least, do not forget to do curing once the footing is set. It's necessary for building comprehensive strength.
