How much settling

 Hi,

We dug a trench to lay some wires in a 2" conduit a foot deep and a
foot wide. After we refill and put sod back on it, how much settlement
can we expect? In other words, how far above level should we leave it?

Thanks!

It depends on how you back fill it.  If you put the soil back 3" at a
time and tamp it or walk on it to compact it....you might be about to
go with only an inch or so extra.

It all depends on how compacted or loose your back fill is "as
placed".

You could need to leave as much ass 4 to 6"...

how about just piling all the soil you took out back onto the trench?

cheers

soil than a waxing moon. . . .. or is it the other way around?

I fill a shade too full-- then redo if necessary.    It is *not* brain
surgery.

*If these are electrical wires the conduit should be at least 18" deep
unless the circuit is GFI protected.  If this is for an electrical service
the conduit should be deeper.
