Hello,
we are currently considering the best way to install patio slabs and how thick they should be. The tiler told us that they could be laid on pedestal supports with open joints, which might feel a bit unstable. Alternatively, they could be placed directly on crushed stone with the joints filled with jointing sand. However, this method would probably result in sandy feet, right? How did you do it, and how wide are your joints? What slab thickness did you choose? What is the best way to install them?
Best regards,
Sabine

I recently read on the website of a major paving manufacturer that terrace slabs should never be installed without joints (3-5mm). Unfortunately, the reason why was not explained there. Maybe someone here knows? It would of course be better without all the sand, since you end up with it on your feet all the time.
Best regards
SabineNo standing water, careful installation, expansion between summer and winter
I’ll see if I can find a photo. The joints are very minimal and not something you need to sweep out.

we also have joints; without joints, a professional would probably need to do the work, I guess. It’s simply not such delicate work. But we also installed it on gravel and compacted the ground beforehand.
Very important: a rubber mallet, like a 10 kg (22 lbs) heavy lump.

Good morning,
our terrace is currently being constructed as well, and the joints are being filled with sand slurry. Does it make sense to finish the top layer of the joints with paving joint mortar?
The sand slurry will probably remain on the terrace surface over time during cleaning and might eventually be washed away or swept out. Would using paving joint mortar be a practical addition?
Good luck

We have 60x40x4 cm (24x16x1.6 inches) terrace slabs with 3 mm (0.12 inches) joints.
Before installation, I spoke with a friendly representative from the manufacturer who explained that the corners are likely to break during installation. They also mentioned that without the joints, rainwater won’t drain properly, which will cause wet edges along the joints. Great idea with the windows in the terrace partition wall. *Thumbs up*

SabineNo, you don’t have that problem. The sand stays in the joint and hardens. Ideally.
