damp-proofing courses Uses

These are layers or membranes of water-resistant materials, such as bituminous felts, mastic asphalt, plastic sheets, cement concrete, mortar, metal sheets, slates and stones, which are attached to the building structure at all points where These damp-proof courses of suitable material where water ingress is likely or suspected should be provided at suitable locations for their effective use. Basically, DPC is provided to prevent water from rising

from the subsoil or ground and seeping into different parts of the building. The best location or position for the DPC, in the case of buildings without a basement, is at plinth level or, in the case of structures without a plinth, it should be placed at least 1.5 cm above the ground level. These damp proof courses can be provided horizontally or vertically in floors, walls etc. In case of basement, DPC laying is called ‘tanking’.
