I’ve seen this design when making ultra light weight structures. It does work but can be difficult to manufacture
Also, looks harder to mow the lawn.

You need to use two brick width for stability.
Is that what we're doing? If I remember correctly, the walls around the houses in my childhood neighborhood were only one brick in width. Also walls around cemeteries and such, I could swear they are not double-width walls.

The point is that a straight wall one brick thick will fall down. Though I didn't see any real explanation of why a straight wall one brick thick will fall down...
The base proportion to the height.
Two bricks wide has a 2x wider base.

It doesn't have the vertical stability to stand on its own. You need to make it thicker (how thick depends on how tall, but the important aspect is the staggered construction of multiple layers giving a similar self-reinforcement) to give it the proper foundation. Keep in mind that it's multiple thin horizontal layers held by a relatively weak adhesive, not a solid object.
A wavy wall reinforces itself against the same forces (wind being the big one) allowing for thinner construction at an equivalent height.

#36This feels a bit like diet clickbait... "use fewer bricks than a straight wall"* *A straight wall of the approximal strength and length of a wavy wall, not just length. My counter would be that from a practical perspective the amount of space wasted by the wavy design seems to negate the usefulness of the design. Probably makes the lawn crew dizzy when mowing it too!
If you have plenty of space but you're tight on money, it's an ingenious solution.
Good point. I'd say if you're tight on money I'm not sure a wall should be at the top of your to-buy list.

#37Yeah but more space, and are therefore the wrong choice a lot of the time.
Which is why they are very popular in the less densely populated and large lot size areas of the English Country side. By the time of the New World, fast population growth meant the economics of brick production wasn't feasible and copious alternative methods were easier (wood/picket fences, wood studs+wire, chain-link or wrought iron/brick + iron). All less long lasting, but cheaper, quicker and easier to install wi…

#39I feel like everyone this far is missing something, or perhaps just I am.
I understand that a wavy wall will be stronger than a straight wall of the same thickness, therefore if you need that additional strength it technically uses fewer bricks to reach it.
That said, if the alternative is a 2 layer straight wall, is the wavy wall equally as strong? Or is it just stronger than the single layer wall?
Without knowing anything about the subject matter, I’d assume that the strength goes in order of single-layer straight, wavy, double-layer straight. No? Seems like needing just the amount of strength the wavy wall provides, and no more, would be a fairly rare use case. Leading to double-layer straights most of the time anyway.

#40Earlier quoted context omitted.
Ever built Lego?
Maybe, a long time ago. For those whose childhood is a long way behind them, would you explain?
Lego are just like those brick. If you just pile them on you have no strength, if you interlock them you have strength in one direction, if you have 2 rows interlocked, you have strength in 2 directions.
