Concrete structures are constantly subjected to movement caused by thermal expansion, shrinkage, and structural loading. These movements lead to cracking, allowing water and aggressive agents to penetrate the structure. Aquafin Saniflex Universal is an advanced elastomeric waterproofing and protective coating designed to bridge cracks and provide long-term durability in demanding environments
