Don't pour concrete down without first wedging something a few inches
down to block it. A bundle of rags rammed into place is ok - but DO
check it's not a straight drop into your 4" sewer outlet, and if it
takes more cement that you thought, don't keep piling it in.

MN| concrete over that? I need to cover it as the shower cubicle
MN| area is about half an inch lower than the rest of the room.

Why not just cover the hole with a thin piece of board then fill the
whole depression?

MN| The main points are that the whole of the room is a concrete
MN| floor with quarry tiles over most of it. I was planning to
MN| level everywhere to the same height as the quarry tiles and
MN| then lino the whole room.

Lino over quarry tiles? Not my choice...
