Structural

Masonry Wall

Masonry or blockwork is a very common way of creating structural and retaining walls. The New Zealand Concrete Masonry Manual describes it best: Blockwork masonry units are hollow and are filled with concrete and allow for the integration of reinforcing steel, a feature essential for earthquake resistant design' (Page 1, 2011, (7)).

At this point, we do want to make it clear that we do out of environmental reasons have a bias against concrete masonry walls at present. The University of Bath in the UK established a list that shows the CO2 emissions of building products and concrete/cement does not do well at present. While concrete sometimes appears unavoidable, we believe the use of masonry does not belong in that category as of 2019. A copy of the report is available below...

Advantages of Concrete Masonry walls:

  • Low maintenance and high life expectancy

  • Good thermal mass, storing heat gained during the day and releasing it later

  • High resistance to fire

 

Disadvantages of Concrete Masonry walls:

  • High release of CO2 during its manufacture

  • High cost to break down and potential landfill of non-biodegradable material
