The NCC Performance Requirements can be met using either a Performance Solution, Deemed-to-Satisfy (DTS) Solution, or a combination of both.

The following is a general representation and introduction to the DTS Provisions for waterproofing in Class 1 buildings (houses). The NCC 2022 waterproofing provisions in Volume Two, aim to safeguard the occupants from illness or injury and protect the building from damage caused by the accumulation of internal moisture arising from the use of wet areas in a building.

The waterproofing provisions in NCC Volume Two require a building to be constructed in a way that prevents potential health risk, dangerous conditions or any damage to building elements which can caused by dampness or waterflow from wet areas such as bathrooms, laundries or the like in a building.

This information is useful for architects, building designers, building surveyors (certifiers), plumbers, builders, and educators.
