Special case;
Hello!
I have a somewhat tricky casting problem that requires tips from experienced tinkerers and inventors
Situation: A 60s house with a basement. Right next to the house foundation, there is a mixture of gravel and stones about 40 cm wide,
this longitudinal stone surface has a partition towards the adjacent flowerbed consisting of buried stone slabs lying
in a line along the house, about 7 meters, standing on edge, largely buried
in the ground. They form, so to speak, a longitudinal collar right next to the house that sticks up about 5-10 cm above the ground. The protruding edge is about 5 cm wide.
Anyway; I need to lay stone slabs for foot traffic across the entire flowerbed and realize that I need to place the new slabs slightly higher
than the existing stone edge to achieve a reasonable slope away from the house.
My plan is to cast an elevation on these stone slabs that stick up on edge out of the ground, with the help of wooden boards and clamps, so that
they become about 7 cm higher. However, I now realize that I probably need to come up with some kind of reinforcement - that is, screw on some kind of edge list or similar to
the existing slabs to prevent the cast elevation from cracking or something similar.
How would you go about creating a reasonable casting? Is there a high risk that the cast edge will crack or fall off with the slightest impact?
Attaching a picture to explain it all a bit more clearly (if that's even possible
As always, very grateful for opinions and warnings.

I would not have cast such a rise, I don't think it holds with a narrow, long concrete footing resting on slabs as you describe. My guess is it will crack due to movements in the slabs underneath.
I would have used pressure-treated wood instead, a pressure-treated beam meant to be buried should last significantly longer.

I've been thinking in that direction. The problem is that I'm not very keen on digging up the standing slabs (which I suspect are 50*50). But I've been considering some kind of wooden beam or round post wood of suitable thickness that I might screw on top of the slabs' edge. I'm holding off for now.......
Thanks for the answer / Jörgen

Place the tiles on the stone edge and you will gain the tiles' thickness of about 5cm. But since there is a flower bed where you will be laying the tiles, it should be easy to dig up the edging stone, allowing you to raise it.
