Terrace ceramic tiles in gravel - Any experience?

One disadvantage is (but this is precisely due to the advantages): subsequent corrections are more time-consuming. But that's just like other lasting things. The disadvantage of durability is inherent when you want to change something. It's basically already a law of nature.

If in a split bed then a maximum of 2-3cm otherwise they start to dance and slide.

And to the corners split bed clamps

In the past, the plates were always laid in split, I don't know why everyone wants to glue them now.

In the past, the slabs were always laid in gravel, I don't know why everyone wants to glue them now.

You are not listening, are you? They wobble, they move. But just do it however you want.

Yes, I am, but you can’t hear any other opinion, can you? I spoke with a master tiler at Raab Karcher; he said gluing is the last option, gravel would be no problem at all, then others like you talk about wobbling and shifting, but also many who say that if the gravel is properly compacted and the gravel is properly leveled, nothing wobbles, slabs laid for 4 years, etc. That’s why I got confused because I’d like to lay on gravel and get 2 cm cheaply from an acquaintance. But if 2 cm in gravel wobbles rather than being stable, I have to weigh whether to take paving stones or thicker slabs. Everything is also a matter of cost. I don’t necessarily want to lay in mortar because of a few hundred euros cheaper slabs, but also don’t want to pay 3000 more for gravel for thicker slabs. To be able to weigh which compromise I want to make, I question things. The forum is not there for me to take your opinion as correct and have to implement it.

But if you don't accept the opinions (which by the way often also are based on experiences) in the forum because they do not correspond to what you would like to hear, then you actually don't need to ask in the forum. Then just commission the master tiler or a company recommended by him and have them give you an extended warranty against rocking and shifting for 10 years. If they don't want to give you that, then you know where you stand.
