I have dug a trench and I am going to put 9" deep footings that are 415mm wide and 14.5m long. Can someone help with how much ballast and cement required?
What ratio ballast to cement for a 600mm high retaining wall would be ok?

3 bulk bags ballast 18/20 bags cement will do, and 6 ballast to 1 cement.
