Negative Side

Term from Waterproofing Services industry explained for recruiters

A "Negative Side" refers to waterproofing that's applied to the inside surface of a structure (the side where water is trying to get in), rather than the outside. Think of it like putting an umbrella under a leak instead of fixing the roof - it catches the water after it's already entered the structure. This method is often used in basements, foundations, and underground structures when it's impossible or too expensive to dig up and waterproof from the outside. While not always the ideal solution, it's an important skill in waterproofing services, especially for existing buildings where external access isn't possible.
