Acceptable solution for weathertight concrete construction

Building a home to take advantage of concrete’s excellent weathertight credentials has become even simpler with a new Acceptable Solution that references the Cement and Concrete Association of New Zealand’s (CCANZ) document -Code of Practice for Weathertight Concrete and Concrete Masonry Construction (CCANZ CP 01:2011).

Clause E2 (External Moisture) Acceptable Solution (E2/AS3) of the New Zealand Building Code (NZBC) came into effect at the beginning of August 2011.

The CCANZ Code of Practice covers the weathertightness of the building envelope for concrete slabs on the ground, concrete walls and associated methods of insulation, concrete flat roofs and decks, and concrete to timber construction junctions.  

The development of this document, and its inclusion as E2/AS3 in the NZBC, will alleviate the current uncertainty amongst consent authorities around weathertight concrete and concrete masonry design and construction.

For further information about this key change to the NZBC External Moisture documents go to the Department of Building and Housing website www.dbh.govt.nz.
