sorry who the hell does this each time ?????? first you tell me to spend a hell of a lot of money on soil, then you start doing the botched work in the next step? all paved areas belong - if you really want to do it properly! - to be frost-proof backfilled with 80cm of gravel! the earth excavation from the house is distributed in the garden for the lawn, etc... no special conditions are needed, except of course for the disturbing stones. for saving 10,000€ you can also rake stones for 2-3 afternoons
sure you should talk to your civil engineer, but he is not impartial but wants to make money. he will always tell you that other soil is better (which is true, as it is sieved without stones etc...). the question is whether it is worth it and above all, do you have the 10,000€ + euros for it?! of course if there is only junk in it you have to replace it at some point, but not because of 2-3 pieces of clay and a few stones.
Who does such nonsense I don't know, I only said you can't just generally say, just backfill with excavated soil. Depending on what will be on top later or how the lawn is supposed to be later, that simply doesn't work. Particularly clay soil is hardly workable properly and later water stands in the garden around the house, where it would have seeped away with gravel. Especially after the last few weeks some appreciate that...
80 cm of gravel under the terrace is nice and all, but the soil underneath must also be load-bearing. So it doesn't help to dump 2 meters of excavation into the pit and then put 80cm of gravel on top.
