I am about to embark on a mission of my own to dig up a previously filled in pool. I did a little preliminary work this weekend with the bobcat and found my bond beam to be in rough shape. This thread has given me valuable tools to possibly tackle the project myself. I have some concrete background and I am in the heavy equipment industry so those things will hopefully help me in the this mission. I have included a pic of what I have discovered so far. This Saturday I will excavate the remaining dirt to see the condition of the remaining shell. Wish me luck. More pics to follow and I know I could use a ton of advice.
