Paving stones settle after one year (Carport track rut)

The problem often lies much deeper ....

for example, when filling around the house, if not every 40cm was vibrated but only the top layer, then it settles further down.

and if it happens only in a narrow strip, I can well imagine that the subsoil is problematic because the landscaper didn't work on it at all.

A good vibrating plate usually only reaches about 40cm deep. If it’s really good, maybe 50cm. But not much more.

Of course, it also always depends on how far down the natural soil was loosened and rebuilt.

There is no house where the parking space is. Likewise, no one except the landscaper filled in there. He cannot pass the buck; he should have compacted layer by layer. I think about 1m was filled there with mineral gravel.

Good, if no excavation was done there, the fault clearly lies with the garden landscaper.

Of course, it saves a lot of time if the area is compacted only once and not, as it should be, 2-3 times to a depth of 1 meter.

I would compact at least twice at this depth.
Around the house, we compacted in 30cm layers to avoid the problem.

take a tamper. Then nothing will sink anymore.
