How to build a Breeze block wall?

Hello! I am obsessed with these blocks, but unsure how to build a wall with them? previous blocks I have seen have a channel for rebar, but the bunnings ones are flat on all sides, do you just use mortar and that’s it?

Hi @hopeaotearoa 

I am assuming your  deck is  timber. 

To answer your question can you  put breeze blocks onto any flat surface for low walls.  The higher the wall the more they fast need more traditional  concrete base and metal  support  rods.  

You are better off putting a timber frame and screwing  decorative panels too it for long term  instead of  railings

But lets  explore

Yes you can actually glue breeze blocks together with outdoor  liquid  nails instead of mortar. This will glue to timber as  well. I do it often for the odd loose  pavers etc  this  defies traditional cementing more premanent builds  but it works all the same.  I just glued a row  of glass  bricks  in a low non weight bearing garden wall it is solid looks  very good in a decorative  way only 600mm height including a besser capping glued on.

Often cemented  capping all to often can be impacted and crumble off out door building glue and polymers hold better.

Why you probably shouldnt breeze  block the deck directly

On a  timber  deck I probaly wouldnt go more than 2 breeze blocks high as they weigh in at approx 16kg each Warp your deck.

- Deck needs mantinace for longer life not possible  with bricks on it.

- Deck might need replacement later on so your wall will need to come down  best to build the breeze block wall on to the ground besides the  deck/

Thanks for such a detailed response. I do appreciate it. I will attempt to build something out of timber that has a similar look and aesthetic.  Wish me luck!

Hi @Jewelleryrescue and @MitchellMc 

Apologies on the extremely late delay but just wanted to send images of my completed Breeze Block wall that you helped me with.

It turned out great and no doubt wouldn't have been possible without your assistance and very detailed instructions.

The wall is the main feature of my on-going, several year back yard project I've been working on for a few years now. The wall was completed around March 2024 and I've since landscaped the entire backyard around it, which is slowly taking shape. 

Thanks again, your guidance and patience with me on this was second to none!

Hello @bodega 

Thank you very much for the photo update. The breeze block wall looks fantastic! I'm sure @MitchellMc and @Jewelleryrescue will be happy to know that your project is now finished.
