Hello,

Maybe try a pier on a large flat base, the base the same size as a few water tanks with holes in them, so you can stack them. Umbrella stands and temporary fences use them, at 200ltrs you have 200kilo and its drainable to a few kilo's.

You can then either look at a sand base or a smaller slab to break up on leaving. If you pad between the pier and the bases you should get little play in between them. Also trying to reset your 80kilo+ concrete block later will be cumbersome.

As for 42, I think it was 6x8, but that was long ago.
