Anyway - I'm doing a lawn. The level of the ground needs to be raised so
I'm going to need to buy topsoil. The problem I have is the condition of
the existing ground. It was recently a building site and is basically
hardcore stones and rubble with a fair amount of sand and poor quality
soil. What depth of good quality topsoil should I use for planting
grass? I don't need a bowling green type lawn but I don't want one which
is patchy either.



How high does it need to be raised? When I dug up my garden a while
back the topsoil was only a couple of inches thick before it was hard
clay. The grass always grew ok but drainage wasn't great.
