what is Plinth

This is the portion of the structure between the surface of the surrounding ground and the surface of the floor immediately above the ground. The thickness of the plinth wall depends upon the weight of the superstructure and the width of the foundation concrete. The minimum height of the plinth is usually kept as not less than 4.5 cm.

The plinth wall should satisfy the following requirements in a building structure in its design and construction:

1. To transmit the load of the superstructure to the foundation.
2. To act as a retaining wall so as to keep the filling in position below the raised floor or the building.
3. To protect the building from dampness or moisture.
4. To enhance the architectural appearance of the building.
