Description

This is a revised 2022 version CP01 Code of Practice for Weathertight Concrete and Concrete Masonry Construction to help establish new standard practices.

This update of the 2014 version was prompted by a need to improve the thermal performance of residential concrete buildings and account for new construction systems.

This code of practice has been prepared for use by practitioners with the appropriate qualifications, experience and professional judgement as a way to demonstrate compliance with the New Zealand Building Code Clause E2 External Moisture. Practitioners using this code of practice should ensure that design solutions meet all the performance requirements of the Building Code.

Scope

This Code of Practice is intended as a means of generic guidance for compliance with the New Zealand Building Code (NZBC) Clause E2 External Moisture for residential buildings as per NZS 4229 scope for residential buildings.

It covers the weathertightness of the building envelope for:

  • Concrete slab on ground,
  • Concrete and concrete masonry wall systems,
  • Concrete flat roofs and decks, and
  • Concrete to timber construction junctions.

The building type shall be as per the following limitations:

  • a) Building use - residential, (housing, communal residential, outbuildings as specified under NZBC Clause A1 Classified uses) with the geometrical limitations of NZS 4229, 1 Scope and Interpretation.
  • b) Buildings shall comply with importance levels 1 & 2 of AS/NZS 1170 - Structural Design Actions,
  • c) Buildings shall be built on good ground as defined in NZS 4229, but with “liquefaction and lateral spread” added to the list of excluded ground,
  • d) The building configuration shall comply with NZS 4229, 1.1.3 except that the total floor area for single storey buildings can be up to 1000m², and
  • e) The slope of the finished concrete roof and deck membrane shall be no less than 1.5°.

This Code of Practice covers three types of concrete walls:

  • A. Concrete masonry construction as specified in section 3.2,
  • B. Insitu concrete construction as specified in section 3.3, and
  • C. Precast concrete construction as specified in section 3.4.

This Code of Practice also provides weathertightness details for four alternative positions for the wall insulation:

  1. On the inner face of the wall, or
  2. On the outside face of the wall (EIFS systems), or
  3. Integral within the wall itself, or
  4. Within a ventilated cavity.
