STANDARDS

New Zealand Standards of relevance to the concrete masonry industry include:

AS/NZS 4455.1:2008 Masonry Units, Pavers, Flags & Segmental Retaining Wall Units - Masonry Units
Provides users and specifiers with the requirements for masonry units used in masonry wall construction.

AS/NZS 4455.2: 2008 Masonry Units, Pavers, Flags & Segmental Retaining Wall Units- Pavers & Flags
Provides users and specifiers with the requirements for masonry units used in pavement construction.

AS/NZS 4455.3:2008 Masonry Units, Pavers, Flags & Segmental Retaining Wall Units - Segmental Retaining Wall Units
Provides users and specifiers with the requirements for segmental retaining wall units used in segmental retaining walls.

AS/NZS 4456:2003 Masonry Units, Segmental Pavers and Flags - Methods of Test
Provides a general introduction and a series of 19 test methods for masonry units and segmental pavers. The tests are for sampling, mean and standard deviation, and for determining dimensions, compressive strength, breaking load, potential to effloresce, core percentage and material thickness, moisture content and dry density, abrasion resistance, resistance to salt attack, expansion, contraction, pitting due to salt attack, expansion, contraction, pitting due to lime particles, water absorption properties, lateral modulus of rupture, permeability to water, rate of absorption and tensile strength.

NZS 4210:2001 Masonry Construction: Materials & Workmanship (supersedes 4210:1989)
Sets out requirements for materials and workmanship of clay, concrete and natural stone masonry to be used in conjunction with NZ 3604; NZS 4229; NZS 4230 for construction of masonry buildings and masonry veneers.

NZS 4229:2013 Concrete Masonry Buildings Not Requiring Specific Engineering Design
Sets a minimum standard for the design and construction of reinforced concrete masonry buildings. When applied by architects, designers, builders, engineers, apprentices, building consent authorities, and building industry regulators, NZS 4229 provides these users with a cost effective means of compliance and practical guidance for designing and building to meet New Zealand Building Code requirements, without the need for specific engineering design.

It provides prescribed methods for the design and construction of reinforced concrete masonry buildings up to 10 metres in height, including domestic dwellings and most other residential buildings, and some commercial buildings. The use of NZS 4229 during design and building provides consumers with assurance that their home has been built to meet the legislative requirements of the New Zealand Building Code.

NZS 4230:2004 Design of Reinforced Concrete Masonry Structures
BIA Approved Document B1 Part one specifies minimum requirements for the design of masonry buildings and other masonry structures. Also applicable to the design of parts of other buildings which are constructed of masonry. Part two provides a commentary on Part one.

NZS 3116:2002 Concrete Segmental & Flagstone Paving
Sets out provisions for the non-specific engineering design and construction of pavements using segmental and flagstone pavers. It also provides New Zealand variations to paver manufacture and tests in relation to AS/NZS 4455 and AS/NZS 4456.

NZS HB 4236 Masonry Veneer – Wall Cladding
This handbook was compiled in 2002 being based on veneer clauses contained in NZS 3604, NZS 4210 and NZS 4229. In the meantime, NZS 3604 and NZS 4229 have been revised and the New Zealand Building Code document E2/AS1 has been published. To date (February 2014) it has not been possible to update NZS HB 4236 although the document does retain important information for the construction of masonry veneer cladding.

Concrete masonry is a staple material of the New Zealand construction industry; a silent workhorse that encompasses reinforced concrete block and concrete block veneer, along with concrete block paving and flagstone paving for pedestrian walkways.

The Concrete Masonry Manual, which was created in the late 1970s as a guide to the design and construction of concrete masonry, has been updated and is available in sections for free download as required.
