Silicone Water Repellent manufacturer introduced that waterproofing agent is a chemical admixture. It is added to the cement. When the cement hardens, it expands in volume, compensating for the shrinkage and tension of the steel bar to generate the prestress and fully filling the cement gap.

Rigid waterproof materials are mortar.
Flexible waterproof materials are of K11 category.
