In India, damp proofing refers to the application of materials that prevent moisture from seeping into buildings but do not withstand water under pressure. On the other hand, waterproofing involves specialized treatments and coatings that create a barrier against water, even under hydrostatic pressure. Damp proofing is commonly used in foundations and walls to prevent rising dampness, while vapor barriers help control internal moisture levels within structures. The effectiveness of moisture resistance is determined by Indian standards and specific test methods, ensuring durability and long-term protection against water damage.
