BITUMINOUS FELTS/MEMBRANE FOR
WATER PROOFING AND DAMP PROOFING
[CODE NO.3486]
Water proofing and damp proofing sometimes becomes very necessary to prevent certain items-often very quick application of any water and damp proofing media which covers the articles and protects the same from water and dampy atmosphere . Most widely used medias for this purpose are bituminous felts which are quite flexible and have some sticky nature to adhere with the surface to which these are applied.
These bituminous felts consists of a textile felt, water proofing compound and resin. There are so many water proofing compounds which can be used for the manufacture of bituminous felts. but only few of them are used commercially due to their limitations. There are two classes of water proofing compounds, one is that of chemically active substances which reactive materials which usually do not react with the material and adhere with the surface with bonding agent.
The main materials which falls under chemically active class are alkaline silicates, calcium chloride etc. In the other class, i.e. chemically inactive class, the materials which are included are chalk, fullers earth etc. Other materials in this class are calcium soaps, resin, vegetable oils, fats, waxes, and coal tar residues and bitumen . These chemically inactive materials are most widely used for the manufacture of bituminous felts for water proofing purpose.
