ᐅ Installing polygonal paving slabs over an existing terrace (concrete slabs)?

Hi!
In 2017, we moved into our newly built house. The purchase price included a typical concrete slab terrace (see photo).
Size 4 x 9 m (13 x 30 ft) plus a corner section leading to the garage (approximately 5 m² (54 ft²)).
The slabs were laid on a gravel bed (see photo from “back then”).
Since we already have a high step into the house (about 19 cm (7.5 inches)) and now want to enhance the terrace with polygonal stone slabs in a Mediterranean style, we are wondering if we can use the existing concrete slabs as a base? The slope is already ideal, and our thought was that the concrete slabs provide a solid foundation for our project.
Is this feasible, and is there anything special we need to consider given our situation?
Good luck & many thanks!

Hi!
Thanks for your feedback.
The main goal of the project isn’t to raise the terrace as high as possible (to minimize the height difference to the house entrance mentioned in the first post), but rather to generally improve the appearance of the terrace. The height difference is just a positive side effect.
So I can follow exactly the same procedure shown in the Hornbach YouTube video and apply cement bonding slurry onto my existing concrete slabs, then lay the polygonal slabs with adhesive afterwards?
Good luck & thanks

Good morning,
after discussions with two landscaping contractors, we are now quite uncertain whether we feel confident tackling this project given the circumstances.
Structure: approximately 8-10 cm (3-4 inches) of concrete (including reinforcement) + around 3-4 cm (1-1.5 inches) of polygonal slabs
Required materials: drain concrete, reinforcing steel bars, trass cement, joint filler
The statements during the conversations with the landscapers were very open and honest. We didn’t get the impression that they were trying to sell us anything. Additionally, their schedules are already fully booked.
Now we are considering whether an alternative might also be a good option...
WPC: We have looked at various options, but even the most realistic-looking solutions still seemed too artificial to us.
Tropical hardwoods: Not an option for us
Local woods: Unfortunately, they have only limited durability
Bamboo: This currently seems to be our favorite. However, there is very little information or user experience available on this, especially in forums.
Can anyone share any insights on this? Allegedly, bamboo decking has continued to develop in recent years and is increasingly sold as decking material (at least that was the advice from a seller yesterday).
Good luck and thanks!

Drainbeton ,Hello GathoWhat is supposed to be meant by "Drainbeton"? Concrete as drainage? A new invention.
Otherwise, everything else is consistent.
Well, whether to include reinforcement in 8–10cm (3–4 inches) of concrete is a matter of opinion. It can be done, but it’s not mandatory.
No tropical hardwoods, but bamboo is fine.
You should take a look at the bamboo forests in Asia. Nothing lives there. It’s comparable to our spruce regeneration areas.

"Drain concrete" Hello
just asked Master Google. It does actually exist. But does it really help?

Hello Steven,
Drain concrete was new to me as well. I learned about it from a construction supervisor.
The installation with polygonal slabs is not completely off the table yet – but maybe we won’t do it entirely on our own and would get help from the construction supervisor for it, carrying out the work at the latest next year while saving some money until then.
The alternative would be bamboo. Unfortunately, there is very, very little information available on that. However, I find this option very interesting.
Good luck!
