What mix to fill a cavity below dpc?
- Thread starter realtek
- Start date
1 part cement : 12 parts ballast.
The oldun is probably right but for all practical purposes we would sling whatever mortar or concrete remnants were at hand down the cavity and tamp it with a stick.
Wet, semi-dry whatever. Just fill the cavity when the beds are reasonably set.

If you're building on stepped ground do take cognisance of Diagram 11, Difference in ground levels.
