Sidewalk Surgery

- Tom Dvorak

Concrete work is hard labor. But for small jobs, I usually find I can do it myself—and for about one-third the contractor’s bid.

This sidewalk is a typical example. The materials and mixer rental cost about $200; a pro would have charged me at least $600. So I saved 400 bucks—not bad! You can do the same. Experience with concrete isn’t necessary, but you will need tool know-how and a strong back. You can follow the steps here and find much more info at familyhandyman.com. Just search for “concrete.“

1 DIG DITCHES

Trench along both sides of the walk at least 6 in. wide and 6 in. deep. These trenches will allow you to set up forms later.

2 CUT A CRACK STOP

When you break up the bad section, a cut that’s at least 1-1/4 in. deep will prevent cracks from spreading to the good section. An existing groove in the concrete is usually the best place to cut. Cut with a diamond blade in a circular saw or an angle grinder.

3 BUST UP THE BAD SECTION

A small section of sidewalk usually doesn’t require a jackhammer rental; try a sledgehammer first. A mattock is perfect for prying up broken concrete. Remove the chunks. For more concrete-busting tips, search for “concrete demolition” at familyhandyman.com.
