Negative waterproofing is typically used in “below ground’ situations in which it is impractical to apply remedial waterproofing to the positive side. While applying barrier protection to the positive side of the structure is always preferable, negative side waterproofing can offer a multi-defence strategy for below ground applications.
Typically, there are two types of negative treatment: First, a correction to the substrate to enhance the watertightness; and second, a hydrostatic coating as a final defence to hold back or mask water from entering the internal environment.
While negative side waterproofing is not a guaranteed process, the success rates for remedial works are very high.
