AS 4654.2-2012 Waterproofing membranes for external above-ground use, Part 2: Design and installation
Standards Australia
This Standard was prepared by the Standards Australia Committee BD-013, External Waterproofing Membranes, to supersede AS 4654.2—2009 Waterproofing membrane systems for exterior use—Above ground level, Part 2: Design and installation.
This Standard has been prepared in response to numerous requests from industry representatives in the field of external waterproofing, especially in the areas of roofs, decks and balconies.
The objective of this Standard is to provide a consistent and reliable approach to the design and installation of external waterproofing membrane systems.
The objective of this revision is to align this Standard with the protocols and requirements as set out by the Australian Building Codes Board (ABCB).
This Standard is Part 2 of a series of Standards on external waterproofing, as follows:
AS
4654 Waterproofing membranes for external above-ground use
4654.1 Part 1: Materials
4654.2 Part 2: Design and installation (this Standard)
Figures throughout this Standard indicate the membrane system as a heavy dashed layer line. The system may comprise a single layer or multiple layers.
The term ‘informative’ has been used in this Standard to define the application of the appendix to which it applies. An ‘informative’ appendix is only for information and guidance.
This Standard sets out requirements for the design and installation of above-ground external waterproofing membranes for use in buildings and structures (for example roofs and balconies).
The waterproofing membranes covered by this Standard are also suitable for landscaped areas.
This Standard is not intended for use in applications such as structures below ground level, swimming pools and spas. It excludes concrete admixtures or penetrant sealers and decorative coatings.
