  Good Practice Guide: Concrete Masonry

Single-skin masonry construction has a small but significant share of the New Zealand construction industry. t is seen as a robust construction system where the structural and weathertightness functions of a wall are carried out by a single construction element.

This revised Good Practice Guide covers single-skin reinforced concrete masonry wall construction meeting the tructural requirements of NZS 4229:2013 Concrete masonry buildings not requiring specific engineering design. It is well illustrated with photographs and three-dimensional drawings to explain the requirements of single-skin masonry from initial design requirements through to the weatherproof coating options.
At the time of publication, the Building Code Acceptable Solutions cite NZS 4229:1999 as a means f compliance. Until NZS 4229:2013 is cited in the Acceptable Solutions by the Ministry of Business, Innovation, and Employment (MBIE), designs and construction to NZS 4229:2013 must be submitted for consent as an alternative method.
GPG-Concrete Masonry.jpgThe guide covers performance requirements, design and detailing requirements, material selection, good construction practices, weathertightness and maintenance. It incorporates the requirements of New Zealand Building Code clause H1 Energy efficiency (3rd edition) and E2 External moisture. It references Acceptable Solution E2/AS3, which in turn references CCANZ CP 01 Code of Practice for Weathertight Concrete and
Concrete Masonry Construction.
The design, detailing and weatherproofing principles of this Good Practice Guide can also be applied to single-skin masonry wall construction that is specifically designed.  A companion to this guide is BRANZ Details, a web-based library of detail drawings for openings and junctions within single-skin masonry, available as ready-to-import CAD files from

This revised Good Practice Guide is an essential reference for designers and specifiers, masons, building contractors, building officials, and tutors and students of construction-related disciplines.
