Thanks for all of the responses. I am going to call the local rental
place tomorrow and see what they have available. An emailer suggested
a diamond masonry circular saw blade for around $49. That is not that
bad. There is no way it will cut through the entire piece though. I
may end up choosing that route cutting as far down as possible, then
digging underneath it to remove the dirt as a poster suggested. Then
pound away hoping for a clean break. Sort of like scoring glass. But
if I can get anything from the rental place for the same price or
cheaper, I will go the rental route. I will keep the thread updated if
anyone is still interested and for future reference.

If there are any more suggestions, please keep them coming. Thanks.

Hello,

I am planning on extending my pond in the coming weeks. The current
pond is about 22' x 7'. I want to dig an extension to make it an
L-shaped pond. The problem that I am having is that I would have to
"dig" through a 6" thick concrete walkway. And I have no idea how to
remove it safely and with a low cost. I quickly tried to pound it with
a sledgehammer, but it did little to the concrete. Not even a crack. I
quickly stopped because I was worried about the fish and vibrations.

Does anyone have any suggestions/comments?

Please see my site for images to get a better understanding of what I
am trying to do. I look forward to ANY responses. Thanks for your time
