Vapor Transmission
Vapor Transmission is a term used in the waterproofing and construction industry to describe how water vapor moves through building materials like concrete, walls, or flooring. Think of it like how steam passes through a cloth - some materials let more moisture through than others. Understanding vapor transmission is crucial for waterproofing professionals because it helps them prevent moisture problems that could lead to mold, deterioration, or damage in buildings. When someone mentions vapor transmission in their resume, they're typically talking about their experience with moisture control and waterproofing solutions.
