There's a 4' x 3' x 1.5' poured concrete block at the bottom of the
back steps that's shifted down and to the left about 2 inches.
I've dug a 12" wide and 12" deep "tunnel" under the block's low end
and can get a small 2-ton bottle jack under the block. With 2x6's
above and below the jack, I can raise the block the required 2 inches
to level it.
Now I need some ideas/guidance on how to permanently support and hold
the raised block in place. I would like to pour cement under the
block, but I don't know how to temporarily hold the block in place as I
removed the jack so I can pour the cement under the block.
TIA for any tips, suggestions, ideas.
