Remodeling the exterior of your home requires an array of skills. A skill area that will most likely come in handy when remodeling is cutting concrete sidewalks to make additions to your home. Most people think you have to jackhammer up the entire sidewalk and start over, but you can easily cut the concrete where needed. Any new sidewalk you install will not match the older sidewalk, but it will cost you less to cut a section of the concrete sidewalk rather than to tear up the entire sidewalk.
Cutting a Concrete Sidewalk
Purchase a diamond concrete cutting blade from your local hardware store. Rent or purchase a cutoff saw and screw the diamond blade into the cutoff saw blade mount.
Mark a straight line across the section of sidewalk you will be cutting with a square.
Read the cutoff saw operator's manual and safety precautions. Put on your protective eyewear, mask and gloves.
Align the blade with the line you will cut. Pull the cutoff saw trigger to turn the saw on and push the saw through the concrete sidewalk slowly and steadily. If the saw is running for close to a minute, pull the blade out and release the trigger to let the saw cool down for several minutes and then continue cutting.
Chip and pry with the large iron pry bar to remove the piece of concrete you just cut free. You may also want to rent a jackhammer from your local hardware store and break the section of concrete into smaller pieces for easy removal.
