Concrete removal

For concrete slabs next to a house what is the best way to remove them? Do you have to worried about them being attached to the foundation and possible craking it. Just thinking of bidding on a job where this could be a problem.

I would use a concrete cutter to detach the slab from the foundation, then I'd just use a jack hammer.

I pulled up a couple of driveway aprons and sidewalks earlier this year and did it with a mini-excavator. One required cutting (concrete saw) next to the gararge because they poured the interior of the garage and apron as one piece.

If it's a smaller job and you're going to use hand tools, you can rent a Hilti demo hammer from home depot for around $50 a day. Keep in mind the quality of concrete varies tremendously. I've had slabs just fall apart and others were so dang hard it took forever to break them up. On small stuff, use leverage and gravity to your advantage. A lot of times if you can pry up part of a sidewalk it will break in the process. Other times I'll have someone pry it up and throw a rock underneath it. Then take out the pry bar and have a couple of folks jump on both sides and many times it will break. Also keep in mind there may be steel or wire in the concrete (I wish I had a metal detector sometimes) to keep it together. If there is, you'll need to have tools to cut it. When I bid concrete demo jobs, I always bid high. It's hard work and can be very hard on people and equipment.

One last thing, call a utility locator before you start demolition work. I've heard of contractors severing gas lines and other utilities buried in concrete sidewalks.

Can you give more details? Is this a porch, patio, walkway or what? Is the homeowner the original homeowner? If so, they might know if the slab is tied into the house. If not, and you absolutely can't tell, then put a clause in your contract.
