I was doing this on a side walk in the front yard, with a very cheap plastic housing circular saw, don't remember the brand. All of the sudden the shaft sheared off. The blade took off and motored across the yard into the street. I started checking limbs to make sure I had all of my parts. Thank the Lord for his protection.

Outstanding Sir I am an Instructor in a Job Coprs cement mason program and you checked all the boxes .I show this video to my students for their first impression of concrete cutting with a circular saw and you are very safe .One recommendation Use knee pads helps keep the knees from getting wet and sore .Years of working in the field have taught me that . Thank you.

That's awesome! Glad it all worked out for you. Makes the job pretty easy.

Good video. One caution would be for concrete that has rebar or reenforcement wire embedded. You'll tell by the sparks. One other comment - if you're doing this in a driveway to repair cracks or spalling, it is not necessary to go full-depth. A partial depth repair will be quicker and be just as complete. Just 1.5" or 2" depth will be sufficient; just let the bottom portion remain. Don't forget to put a dummy joint in the repair, same spot as the original. To each his own on the corners. You can cut PAST the other cut if you want a complete cut corner; or, cut TO the other cut then chisel out the remaining concrete left in the corner.

Thank you for showing us the breaking of the cement at the end.

It works, but I wouldn't use my circular saw. The saw blade is $30, and left my saw in terrible shape. The concrete slurry gets into the saw motor and gummed up the saw so bad that I couldn't use it again. You can rent saws specifically for concrete for less than $100.

Great video. This is exactly what I need to do, and now I know to use a GFI and to keep water on it.

I have a worm drive skill saw, will water damage the circular saw? I thought you could still get shocked, even tho plugged into GFI.

How hard is it to cut through the reinforcing bars within the concrete ? does it slow you down and does it break teeth off the saw blade ?

@mgherter

Tough, this isn't the right kind of blade for that. What's worked for me is to kind of cut around them (you'll end up making more cuts in the concrete), and then when you have a good view of the rebar come in with either a reciprocating saw with a Diablo blade or switch to a circular saw blade that is for metal cutting. Rebar absolutely adds a PITA factor to something like this, but it can be done. It just takes a lot longer.

Thanks! My wife recently cut her foot from a clothesline pole. My mission is to cut the cement out from where a clothesline used to be. The previous owner of the home I live in now cut the pole but decided not to take out the damn cement. I have a circular saw but do not know which one to use to cut the cement buried in the ground. Would this work?

@CoolStuffGuysLike

The saw will cut the cement but since it is probably very deep, you will need to probably waffle cut it and then smash out what you can. If you can get it a few inches below the surface you can cover it with dirt and plant grass seed. Depending on how wide the diameter of the pour is, you can also try just sledge hammering it to break it up. Definitely wear long pants and a face shield though because you will have to hit pretty hard which could cause some small pieces to go flying.

Mr Sir if that’s all you have, then I guess. All that blade is really doing though is scaring it. That concrete is at least 4 inches deep “probably deeper”. So he is not by any means cutting all the way through. It should also have mesh if not rebar. So when he hits the area within the cut, the impact of the hammer will effect the masonry surrounding. Could lead to damage later on.
