Removing old anchor bolts from cement.
Posted on 5/20/17 at 9:02 am
Posted on 5/20/17 at 9:02 am
Removed the old pool slide, circa 1985. Old blue one Jennifer Jason Leigh was sliding down in Fast Times at Ridgemont High. Slide came down with little incident. Now I am left with the anchor bolts that stick up about a half inch.
I've watched a few youtube vids but they range from idiots with hammers all the way to using a feww hundred dollars worth of equipment to a guy trying to sell you his own removal tool.
My hope for this project and this thread is a trip to Harbor Freight and a fifty dollar bill needed max. I assume a cheap assed angle grinder with a metal cutting wheel. However, the "idiot with a hammer" intrigues me. He basically bashed the end of the bolt and the then punched it down into the concrete. This could only be done if the guys installed the anchor bolts correctly. IN 1985!!! I was 11-12 years old, so I am not responsible. The guy in the video was assuming threaded collared anchor bolt.
Any help from the real men who AND USE tool belts on this board? Thanks.

Why don't you already own an angle grinder? You fail as a man. Go get one and fix the anchors and fix yourself.

as far as removing it like unscrewing it, I don't know. But to get the convo started, you could cheaply cut it off as close to the cement as possibly and then grind it flush. You can get a cheap cut off tool either electric or for your air compressor for even cheaper if you have a good air compressor.

The correct answer is to pull up all the concrete and replace it all, add a swim up bar and a hot tub while you are at it...

That doesn't side right. The only way that happens is if they were post installed and they went too deep when they drilled the hole.
Another problem with hammering is damaging the concrete.
How do you want it to look when finished?
Eta:
I would cut down as low as possible and then drill out a portion of the anchor below concrete and fill with caulk or grout.

Use a sawzall with a blade for metal. Cut it as flush as possible and grind the rest if needed.

Id cut it flush using a long metal blade on a sawzall and then try and hammer down a little bit using a hammer and punch.

Already have hot tub. My liver cannot sustain a swim up bar.

Right. Installing them "too deep" was a suggestion in one video for "Later, if you decide you don't want them."
I want it to look decent. Just leave little grout patches when done.

I know those concrete cutters are big gas things, but I'm not sure if you could use an angle grinder to cut a small piece of concrete? You probably could I don't see why not? You could probably just cut a small like 4"x4" square of concrete out around them and then pour in some quickcrete. I'm sure you could do a smaller hole than that too.
I would think if you hit it with a small sledge you'd break up the concrete along with removing the bolt, and by break it up I mean risk a bigger mess than just cutting it out. But I don't know.

I've admitted as much in the OP. Get off me man!!

Another option is to figure out something else that 'needs' to be tied down with them, haha

Forgot to mention. 1985 MEANS pea gravel. I don't think there was another option. So busting up or cutting a 4"x4" square will look worse IMO. No way to match pea gravel after 30 years of exposure.
Angle grinder or sawzaw? Are both to be had at Harbor Freight for the same $$$

Angle grinder

Use a couple washers flush to concrete and tighten nut down until anchor starts to move or the bolt snaps....grind flush...I would not be striking metal in 30+ yr old pea gravel concrete...metabo blade to cut....or if you can borrow or buy a dremel tool....cut flush then you can burr it down carefully below flush to back fill with some caulk

I would strongly recommend you don't go with hammer method.
