I had all the wood already from privacy fences that neighbors had torn
down and offered me the scrap.


I thought a long 2x4 or 4x4 might be the best way to lift the concrete
square, then fill underneath with gravel, sand, or dirt. Probably
safer than using a hoist/chain. There's no erosion in the area but
there are plenty underground water veins.
