Call a waste management company and have a large dumpster delivered to your home. You can omit the dumpster if you own a large truck and would prefer to take the debris to the dump yourself.
Put on sturdy boots, work gloves, a face mask, goggles and ear plugs.
Start about 12 inches from the edge of the patio and squeeze the handle of the jackhammer to turn it on. Place the head of the jackhammer into the concrete. Break through the concrete all the way to the ground. Break up enough concrete to begin removing large pieces. Turn the machine off by releasing the handle.
Work the tip of the jackhammer under the concrete at an angle. Press down on the handle of the jackhammer to pry the concrete loose.
Move the jackhammer one foot to the left or right and repeat the process. Continue breaking up the slab until you have loosened 4 square feet of it. Lift the pieces from the pad and discard them in the dumpster.
Repeat this process, working in 3 to 4 square foot areas, until you have removed the entire patio.
Shovel all small, loose pieces of concrete into a wheel barrow and discard them in the dumpster. Call the waste management company to come and pick up the full dumpster.
