- We can use Chemical waterproofing products, and sika waterproofing products for the purpose of waterproofing. However, concrete's resistance to moisture penetration is improved by adding chemically active water-repelling agents like soda and potash soap. These admixtures prevent water penetration of dry concrete. So far, no established track records are available to prove the life of chemical waterproofing
- These products have a tendency to become brittle and crack up due to stress in buildings, especially thermal stresses. These products are cement, silica, or polymer-based and are specially formulated and designed to control the capillary pores. These products not only make concrete waterproof but also help in resisting water penetration.
Here is the list of waterproofing chemical products in Nepal and Sika waterproofing products in Nepal and their use.
