What kind of gravel gutter did you make?

Around 18 thousand. 90 sqm of paving, granite curbs all around, 20 meters of granite wall as terrain retention and entrance podium are included. I made the granite gravel for splash protection myself, the landscaping companies wanted pharmacist prices for it...

By the way, our lawn also grows very poorly directly next to the curbs, where the roof overhang still causes dryness. The concrete seems to literally suck the moisture out of the soil. In the photo, the lawn is further out, there it works fine.

Here is our version with granite. Shortly after the rain. You should be able to pressure wash the moss off if the stones are big enough. I just noticed that the gravel has settled a bit more. I need to top it up again.

That's true, the stones have settled for me as well.
