ᐅ Are 120x30x2 cm patio slabs recommended?

Hello everyone,

we are currently planning our terrace and are considering using 120x30 cm (48x12 inches) terrace slabs with a thickness of 2 cm (0.8 inches), laid on gravel.

Terrace slab with wood effect (porcelain stoneware 30x120x2 cm):

We just have some concerns that due to their 120 cm (48 inches) length, these slabs might be particularly prone to breaking.

Has anyone had experience with slabs like these, or what is your general opinion?

There are also slabs available in 60x60 cm (24x24 inches), but of course, they don’t look as nice with the wood effect.

I would really appreciate any experience, opinions, or suggestions!

Thank you very much and best regards!

Why don't you use wood?

30 by 120 by 2. Two! In a gravel bed. This is not mine. That will break.

Because of the maintenance required and the durability of the patio slabs compared to wood.

So this kind of installation is definitely not done in gravel, but rather in fine crushed stone. We will be installing 90 x 45 x 2 millimeters (3.5 x 1.8 x 0.08 inches) here soon, but it will still take 1-2 weeks.

Sorry for using the term gravel; I actually meant fine gravel, to be precise.

What did your patio installer tell you about your 90x45x2 cm (35x18x0.8 inches) or even larger slab sizes, and what did they recommend?
