A couple of basic concrete questions.

I want to bury a 4" pipe in trench under my driveway. What is the best method for getting down to dirt?

A also want to remove a 4'x4' piece of walkway. What is the best method for removal?

I assume the driveway is concrete. Diamond blade saw and chisel and hammer. Then you need to go below frost level with that pipe.

For the 4 x 4...Sledge hammer.

Use a saw like that.

You can save a ton of work, and wear-and-tear on your hammer and chisel, by renting a 90-lb. electric jack-hammer for half a day. Using it will enable quick removal of both the concrete from between the trench sawcuts and the 4 x 4 (complete) slab. I used one to remove close to 120 S.F. of concrete a few years ago, and it cost less than $50 for half a day. My slave-girl (aka the wife) couldn't keep up with me, loading the chunks into a wheelbarrow and then wheeling them around the house for throwing into the pickup truck.

I don't see a need to locate the pipe below the frost line. The concrete driveway and its gravel base aren't, meaning they are heaving in freezing temperatures. What's wrong with allowing the pipe to heave with them (assuming it's not carrying water)?
