According to the plans, I have to fill the cavity of the cavity wall
I'm building with a "weak mix" of concrete up to ground level and
sloping down towards the external leaf.
What would be a suitable weak mix to use here ?
Also, anyone know why a weak mix is specified for this use ?

Suppose I have to do what the BCO expects really.
I got the answer off paving expert. I usually do concrete 1-2-4, weak
mix stated as 1-3-6, nice and easy to remember.
Anyhoo I'll probably use a jumbo bag of ballast about 1-8, just about
the amount I need.
