OK. You at least _sound_ as if you have knowledge hereGG.

I was basing only on my attempts at shed and house building over the
years. I know that if you go too deep, you can be in real trouble. I
can see where the paving would have loose dirt under it. But I am sure
that I remember where somebody dug a trench wrong (to one side of the
trench location, instead of in it, if you get my meaning) and had to
do a lot of mucking about. It was on a hillside with very heavy soil
IIRC.

Anyway. It was a long time ago. I bow out, saying only "better safe
than sorry" as far as my warning goes. In other words better to open
my mouth and sound like a fool than risk some other poor *******
acting like one! G

Typical construction practices are to compact backfill only where paving
will be place right up to the building. For lawn strips etc., compaction is
not necessary.
