In engineering, particularly in civil engineering and construction, D.P.C. stands for Damp Proof Course. This is an important layer in a building's structure designed to prevent moisture from rising through the walls from the ground. Moisture can cause significant damage to structures, so the placement of the D.P.C. is crucial for the longevity and integrity of a building.
When constructing a building without a basement, the correct positioning of the D.P.C. is at the plinth level. Therefore, the best choice is:
(a) Plinth level. ;
