comment Is it ok to use pneumatic tools underwater
It' 8 feed underwater. It's close to my dock. I can try to use a giraffe jack, one of 2"x6x8' with 2 chains. I will jack the piece with the jack and a chain than tight the second chain with the 2"x6". I lower the jack and retight the first chain. Repeat until the piece of concrete go out of the water. I will try to move or break it outside.
