Removal of a concrete wall can be a daunting task for a beginner. It will require intense effort and specialized tools. However, the project should not be off limits, as long as you are in reasonably good shape. Many of the tools you'll need are heavy, and the rubble once the wall is removed may be very heavy.
Drill small holes throughout the wall with the impact drill. The holes usually should be about 8 inches apart, but drill the holes in the mortar on the corner of each block of a concrete block wall.
Chisel into the holes with a ball-peen hammer to widen them to about 3 inches in diameter. Begin removing sections of the wall with the sledgehammer. If the wall is over your head, make the first strikes with the hammer at chest level, making sure that you move after each blow to a clear spot. If it is a lower wall, start at the top of the wall and work your way down.
Pick up the rubble and place it the wheelbarrow.
Remove the footing of the wall with the jackhammer. This is the most important part if you plan on planting in the area. After you have removed the majority of the footing, use the shovel to dig up any remaining pieces of rubble.
