Yeah 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 with almost the same benefits (fencing of pets + livestock, property demarcation, security). Which is why you don't see them nearly as often outside of Europe (Asia having used their own alternatives better suited for their environment and needs, Africa having had New World techniques used during colonialism).

Did my adblocker accidentally filter out the explanation? Following the link which is supposed to explain another thing, why it is more resistant to lateral forces, it contains an explanation: > The parameter a is the amplitude of the sine wave. If a = 0, we have a flat wave, i.e. a straight wall, as so the length of this segment is 2π = 6.2832. If a = 1, the integral is 7.6404. So a section of wall is 22% longer, bu…

You need to use two brick width for stability.

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...

This 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 follow the link in the post explaining the math behind everything, it says: "They use more bricks than a straight wall of the same thickness but they don’t have to be as thick."

True, but they use less bricks than a straight wall of the same strength, because the straight wall would have to be thicker or have buttresses. So it depends what you’re doing - does the wall have to withstand that kind of loads or not?

> ...does the wall have to withstand that kind of loads or not?

If you want the brick wall to last, and you aren't building it on either bedrock or a deep foundation ($$$) - then your three choices are (1) build it to withstand substantial horizontal loads, (2) pay more for regular maintenance, and (3) wall will topple due to forces from normal soil movement.

I’ll save folks some reading: they’re comparing a very thick straight wall with a much thinner wavy wall.

The primary point is that you can't make an equivalently thin straight wall due to natural (wind and gravity, primarily) forces. Kinda weird to summarize it without the crux of why.

Maybe, a long time ago.

For those whose childhood is a long way behind them, would you explain?

If you have plenty of space but you're tight on money, it's an ingenious solution.
