Using the stage storage tool works well for basins, but I can not get it to work when the waste starts breaking ground (in fill).
What I need is the solid created between two surfaces, sliced at 1m intervals.
I'm guessing that you have two surfaces, excavated existing ground and a top surface for the waste. If the excavation is a basin then you would be able to get a volume to the surface from that. The second volume could be calculated using the top surface, from the ground up to the top of the pile.
I believe there is a way to create surfaces that would allow for stage storage calculation when the excavation is not a basin but it definitely would not be automated or easy.

OK, I know some of you guys already have certain ideas about me. What if you visualized this in reverse? Draw a basin that represents this mound of waste upside down. I'll leave it at that for the time being.

Thanks for the feedback,
I tried inverting the facility as you suggested. The volume surface shows the correct capacity (= flat surface / design surface - flat surface / existing ground) but, the stage storage data is about half the capacity.
I think it is caused by the uneven ground profile.
