Hi Rod, no I didn't check as I am not a builder and I wasn't watching
- I only saw the finished result.

What I am trying to get a feel for here is how long a 100mm depth of
concrete inside should take to dry indoors. If it takes longer than it
should, there is a problem, but I am not sure I have a problem right
now. That is what I need to find out before I have him dig it all up
again.
