Cutting the piling to expose the rebar, below ground level.
John will form up a cast with rebar and type 1 cement to bring this post up to the correct height. He said it's not a problem to do this. So that will be done another day. We have finished driving piles. And that's a good thing. We may fill in a portion of the cavern, but there is no need to crush and fill it all. That's why we went with the pilings. It turned out to be a wise decision.
Everyone is happy that the pile driving is done!
