In this damp proofing method, layers of membrane of water repellant material are installed between the source of dampness and the area surrounding it. The layers that are installed are made with materials like asphalt, plastic, polythene sheets, cement concrete and bituminous felts.
- Integral damp proofing
In this type of damp proofing, during the process of mixing concrete, water repelled compounds are mixed with the concrete or mortar mix. These compounds prevent moisture from seeping into the structure by acting as a firm barrier. Though the quantity of the compound depends on which material and brand you buy, typically one kg of the compound is added to one bag of cement to make it waterproof.

Surface treatment comprises filling up the holes of the surface that experiences dampness. Lime cement plaster, cement coating, paints, varnishes, bituminous solution are used in this method of dampness treatment.
