Integral waterproofing uses chemical admixtures, usually a dry powder or liquid added to the concrete mix at the batch plant or the jobsite. Some forms of integral waterproofing will even self-heal minor cracking.

BIS is a statutory institution established under the Bureau of Indian Standards Act,1986  to promote harmonious development of the activities of standardization, marking and quality certification of goods and attending to connected matters in the country.

Integral waterproofing compounds for cement mortar and concrete product has been specified in IS 2645:2003 by Bureau of Indian Standards.

SCOPE :

This standard covers the requirements for integral water proofing compounds for cement mortar and concrete which shall be assessed by:

a) The permeability to water of the specimen made from cement sand mortars, with and without addition of waterproofing compound under test, by measuring the percolation of water through standard specimen cylinders.

b) The physical tests of setting time and compressive strength of cement by admixing the recommended proportions of the mortar/concrete waterproofing compound and comparing the results of similar tests on the same cement without addition of the compound.

Note 1 - Integral waterproofing compounds for mortar and concrete shall be used in such proportions as recommended by manufacturer but not exceeding 3 percent by weight of cement.

Note 2 - For the purpose of all the requirements in this standard, cement shall mean ordinary Portland cement 33 Grade, 43Grade or 53 Grade conforming to IS 269, IS 8112 and IS 12269respectively. By agreement between the purchaser and the supplier, testing of waterproofing compounds may be done with Portland slag cement conforming to IS 455 or Portland pozzolana cement - Fly ash based conforming to IS 1489 : Part 1 or Portland pozzolana cement -Calcined clay based conforming to IS 1489 : Part 2.
