Two of the most common forms of waterproofing are positive side waterproofing and negative side waterproofing. Positive side waterproofing essentially means that the waterproofing materials is being directly applied to the surface of the structure, which will have direct exposure to water. Waterproofing an outdoor deck or driveway would be an example of positive side waterproofing. Negative side waterproofing on the other hand is used for interior projects on already existing construction. Essentially, this type of waterproofing is only used on inner surfaces such as interior walls in basements. During negative side waterproofing, the surface that is being waterproofed is not supposed to come into direct contact with water. Blind side waterproofing is usually used during new construction projects, particularly where there are space limitations such as property line encroachment. This space limitation prohibits the ability to properly and effectively excavate the site for full waterproofing. This type of waterproofing uses specific techniques that allow for proper waterproofing despite any space limitations.
