Hello everyone,

Of course, you can find many ideas for retaining walls on Pinterest, but most of them are not from an average everyday garden. Do you have retaining walls on your property, and if so, what do they look like?

I need a slope support behind the garage about 1.5m (5 feet) high and a retaining wall for the terrace that should be about 1m (3 feet) high...

Greywacke... I hadn’t heard that term before.

I always like learning new things (and then forgetting them again ), so I looked it up...

Do you mean exposed aggregate concrete?

Exposed aggregate concrete ... also an option,
Surface made of many small pebbles in a gray concrete slab, terrazzo look.

No, I meant terrazzo ... (doesn’t have to be made so elaborately)

well, these things only cost $2.20, so I’m not sure if doing it yourself is really worth it. Have you ever done it? Do you have instructions?

I don’t think the “doing it yourself” referred to the bricks themselves, but rather to the wall as a whole?

"With the hollow concrete blocks, I’m also worried that the mortar might fall off"

I assume that the durability mostly depends on using the right materials. With a bonding primer and the appropriate plaster or render, it should last a long time (I say this as a non-mason). One possible issue could be moisture accumulating behind such a wall, but that also depends on proper construction methods. If you have a builder or mason you trust, I would take the risk if you’re comfortable with plastering/rendering.

Hollow blocks are also available with different surface finishes, so they don’t need plastering, and the advantage is that you can make them yourself.
I assume by "hollow blocks" you mean formwork blocks and then skip the concrete filling?
