Damp-proofing integral treatment

Integral treatment consists of adding certain admixtures to the concrete or mortar during the mixing process, which act as a barrier to moisture ingress under various principles when used in construction. Admixtures such as chalk, talc and filler earth have a mechanical principle of action, meaning they fill the voids in concrete or mortar, making them dense and waterproof. Compounds such as alkaline, silicates, aluminum sulphate and calcium chloride work on the principle of chemical action, meaning they react chemically and fill the pores to resist water. Similarly, some admixtures such as soaps, petroleum oils and fatty acid compounds such as calcium and sodium ammonium stearates work on a reactive principle, i.e. react with concrete as admixtures and become waterproof. become
