Damp Proof Course or DPC is the protective layer applied to prevent the rising of moisture to the walls from the ground due to capillary action. It is usually 2.5 cm thick with a ratio of rich cement concrete 1:1.5:3 or 2 cm thick with cement mortar 1:2 mixed with standard waterproofing material. It is provided from the plinth level to the entire width of the plinth wall, and the quantities are calculated in square meters (length x breadth). Usually, DPC is not provided at the sills of doors and verandah openings, for which deductions are made. In most cases, 1 kg of cem-seal, Impermo, or another definitive waterproofing compound is used per bag of cement.
