ᐅ Patio slabs used for a parking area?

Hello everyone,

I have the opportunity to get a large quantity of patio slabs at a very good price. I would like to use them for my parking area.
The thickness is 3.8cm (1.5 inches). These slabs are not rated for vehicle traffic. The manufacturer is KANN.
We don’t need to discuss the risk and warranty situation. I am just asking about practical experience: has anyone done something like this, and did it work?
For example, my neighbors laid 4cm (1.6 inches) thick slabs as a path where their in-laws sometimes park—no problems or cracks, but that is only occasional use.
So I wanted to ask here. Thanks!

Of course, you can install them there... and cracks are to be expected—depending on the subfloor, sooner rather than later 🙂

Hello,

I had a conversation just last week with our landscaping contractor about this. We wanted to install 5 cm (2 inches) thick slabs throughout the entire driveway, but he said they wouldn’t last very long without cracking.

Maybe it would be different with a concrete base, but with gravel, the risk is too high.

We will now go with 8 cm (3 inches) thick slabs.

You can forget it. Quite quickly, you will have cracks, especially when we experience another heat/cold period and there is a lot of weight on the slab.

I just browsed a hardware store catalog out of personal interest. They offer paving stones that are 6 cm (2.4 inches) thick and labeled as "suitable for car traffic." I assume they wouldn’t market them that way (to avoid complaints) if it was certain that cracks would develop. Whether the difference between your 5 cm (2 inches) and 6 cm (2.4 inches) thickness is significant, I don’t know.

I also did a quick online search and found a note stating that for private driveways, 5–6 cm (2–2.4 inches) thickness is sufficient if the base is properly prepared.

I don’t have practical experience yet, as we are still in the "waiting for building permit / planning permission" phase.

That only works with an ultra-light vehicle. I recommend the Peel P50.
