The New Zealand Concrete Masonry Association (NZCMA), with support from the Department of Building and Housing, and Building Research, has produced a code of practice for weathertight construction of concrete masonry.
There has been much consideration recently of weathertightness in general construction. The issue is also important for concrete masonry buildings containing habitable spaces where the presence of moisture would lead to the formation of mould and mildew.
This guide will provide information for those considering solutions for compliance with Clause E2 (External Moisture) of the NZ Building Code.
Industry consultation with sectors associated with concrete masonry means the code of practice reflects substantial experience in weathertight detailing of low-rise New Zealand concrete masonry buildings.
