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).

Paved patio made of gray rectangular slabs, grass on the left, planter on the right, shadow over stones.
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”).

View through glass door of steps made of paving stones leading to a grass-covered garden behind a fence.


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!

Get help from the landscape contractor
Hello Gatho

Do some research on the garden and landscaping contractor in question. The internet can be very helpful here. Pay attention to reviews. There are many unreliable contractors out there. It’s incredible how many incompetent ones are around.

Just to ask a simple question, this approach is basically about leveling out the height difference as much as possible, right? Or not? Otherwise, the 8-10cm (3-4 inches) of concrete wouldn't really make much sense, would it?

Hi!

That is just a positive side effect that the height difference gets evened out. I understood from the landscaper that a height of 8-10cm (3-4 inches) should be necessary!?

@Steven
Regarding polygonal paving, I would also stay in close contact with the landscaper. I have now contacted 2-3 (with good reviews from the region).

My main concern was to find out how recommended bamboo is as an alternative and what experiences there are with it.

Good luck!
