(Unsure if this is the right forum or if it belongs in garden?)
I'm about to build a retaining wall, about 90cm high, and there's been some discussion about whether it needs to be glued.
I argue that it doesn't need to be, because the ridge on the back of the stone holds the stones in place.
But my father-in-law brought in some masonry company (the kind with rough Swedish and foreign-registered cars) and they said you should glue them.
Which is more correct?
I’m about to start laying the stones now and I don't have any glue at home (I also like the idea that you can remove/change the wall later if it's not glued).

I realized that I lied a bit, we will make a staircase next to the corner (didn't think about that when I wrote), so there will be no angle support directly there. (I have removed this about the angle from the original post)
-The wall will round a corner ("backward") a bit, but then ends, so no huge support.
However, the wall is not that long, maybe 3-4 meters.
Would you still say that it's safe to proceed without glue, @thomas33?

As they say, go out and put up your wall, it's leaning inward. To be really sure, when the wall is up, put a Platon mat behind and backfill with drainage gravel or macadam + mat in the following order
From the outside: cracked stone -- Platon mat - gravel - a fabric against the gravel - soil
This prevents water from reaching the stones and freezing, perfect.
The most important thing is the footing for the wall, it must be completely stable and not able to move, then it will be good.

Thank you!
Let's keep going and see what happens
I don't think the height is a major concern. I've seen different recommendations on maximum height and have also heard of many who have built quite a bit over these.
My estimate of 90cm is a bit rough, I think it might be slightly lower in reality. Then it lies about 10 cm below the ground surface and will be right against asphalt later.
I think the base will be stable enough. The ground was already pretty compact when we dug, and then we've laid a fairly thin layer of gravel and compacted it.
Feels good *jinx*
I'm planning to fill with macadam behind and geotextile, didn't know about Platonmatta so I'll need to check that out!

Everything seems fine, something not mentioned here is that you should ensure there is good drainage behind, preferably a drainpipe if possible since the bottom is slightly lower, so that water doesn't accumulate there and freeze your wall, as there is asphalt and it's well-packed around, poor water conduction on such material.
Thought about that before as well, if we should have had a drain under the wall, but we took a chance there and are testing without it. It's possible that I'll place a drain at the bottom behind the wall before we fill later.
Is this the same as platonmatta? https://www.byggmax.se/gjutning-och...tisolering-av-husgrund/fuktisolermatta-p21203L Liteavvarje said:
The one you linked to is a sort, available in 1 meter width, it doesn't really matter what you use to put behind it as long as it is waterproof.
Place it behind at the bottom, it will be fine, I don't think much will come in, but you mentioned asphalt on the front side, make sure there's no slope towards the wall, as water will get in between. If possible, you can leave some gaps under the bottom stones so it drains to the drainage.K kurre_kul said:
