In ordinary residential and public buildings, the D.P.C. is generally provided at -

Concept:

Damp-proof Course (D.P.C.)

• To prevent the entry of damp or moisture in the building, the damp proof course (D.P.C) is provided at various levels of the entry of dampness into the building.
• At present, generally, all the buildings are given the treatment of damp-proofing.
• Thus the provision of a damp-proof course prevents the entry of moisture from walls, floors, and the basement of a building.

General Principles While Laying Damp Proof Course:

• Damp proofing course should be so laid that it should provide continuous projection.

• It should be horizontal or vertical.

• A horizontal damp proofing course should cover the full thickness of walls, excluding rendering.

• The damp proof course should not be kept exposed on the wall surface, otherwise, it may get damaged during finishing work.

• When a horizontal damp proof course is continued to the vertical face, a cement concrete fillet of about 75 mm radius should be provided at the junction.

• At junctions and the corners of the walls, the horizontal damp proof course should be laid continuously.

• The mortar bed supporting the damp proof course should be even and leveled and should be free from projections so that the damp proofing course is not damaged.

Hence, In ordinary residential and public buildings, the D.P.C. is generally provided at "plinth level".
