Paving stones on a gravel bed with cement joints

P.S.: A drainage channel will be installed in front of the [Gargentore].

Hi,

the VDW840+ can also be installed afterwards, it's just that the preparation effort is higher... No, it is not elastic, but there is a product from ecoStones, which is a solid joint with a "Green" binder, a natural binder made from some plant extract instead of plastic resin. This is reactivated by moisture (e.g. rain), adheres again and again to the paving stones (when the side adhesion breaks off, it is practically recreated) and cracks etc. fill up by themselves... I haven't personally processed it yet, but it is supposed to be great when installed, and I find it pioneering for the future because it contains no chemicals...

Drainage should be done as planned with a drainage channel or point drain (e.g. yard drain), I simply let it run from the terrace onto the lawn at home and that's fine... But even if you only fill the joints with sand, you should do this, because with heavy rain, water passes through the sand joint just as little, moreover, dry sand takes its time to absorb the water downward, with heavy rain it rather washes off the surface away from the sand... A joint made of grit is indeed more ideal but not feasible with narrow joints

Thanks. The thing with the plant extract joint is interesting. However, I am always a little skeptical of quite unusual new products on the market. Someone should have tried it for 20 years first, haha. I have never seen a joint made of gravel. Except for grass pavers with gravel instead of grass. Do you have concrete stones or natural stones in your yard and garden?

A gravel joint is probably the technically correct method, I think it sucks because with every rain it washes out the gravel and you also have to sweep it out.

Please, thanks to the slide the water can also drain off well...

you should also check the development plan to see what is allowed. in my building area, areas like driveway and terrace must be made of permeable material. if someone gets involved and notices it, you might possibly have to remove the pavement again.
