Water Proofing Methods

Water proofing admixtures specialized in preventing concrete from water penetration.

Water Proofing Methods

Water proofing admixtures achieve their aim by various three methods.

Water proofing admixtures reacts with calcium hydroxide. Calcium hydroxide is the compound of cement paste and make concrete hydrophobic. Animal fats, stearic acid and some vegetables are the example of such kind of admixtures.

Second method of making concrete hydrophobic is by contacting cement paste with the coalescence. Coalescence is an alkali by nature. Alkalinity property of coalescence breaks down the emulsion.

In the third method, some fine materials are used that form a coating over the surfaces. Fine materials should also comprise of some hydrocarbon resins or coal tar pitches or calcium stearate. These compounds form the hydrophobic coating over the surface. It is very difficult to completely coat the entire surfaces. Therefore, complete waterproofing of a surface is unlikely to be achieved.
