How to remove concrete anchors

In this video I remove some concrete anchors, sometimes called thru-bolts. It’s important to remove these when they become redundant, as they pose a serious tripping hazard.

With the smaller dynabolts I have found if you can push the bolt in a few mm then you may be able to get a pair of needle-nose pliers onto the _split expansion sleeve_ then you have a chance of being able to pull the outer sheath up into the hole. This then allows the flair / flare on the _split expansion sleeve_ end to fit back through the hole and be extracted. The advantage if you can use this method is the dynabolt can be reused since you will have all parts of the fastener removed from the hole. I have been successful doing this about 75% of the time using up to M8 sizes. I haven't needed to use larger sizes so don't know of this will work on M10 and up because they have a thicker metal on the split expansion sleeve so it may not "unflair" itself enough to pull bac through the hole.

*Thank You* for the video. It is always good to have another method to use if your goto one doesn't. Much appreciated. 👍👍

I primarily build Outdoor wooden cat shelters and wooden giant sized viking style chairs while I'm in very early stages of testing out a handyman service ( lasted a short while on site with a small company based in Ilkley restoring Calverley Old Hall as an apprentice joiner )

These videos are always informative and feel you can tell you know what you are doing

I buggered up installing an anchor bolt in a garage defender base plate ( didn't drill deep enough and had 1.5" Bolt sticking out the concrete

Grinder saved me on this
Really enjoy trying my hand at things but often get defeated too easily when i get things wrong

Better to view as learning from mistakes and do better next time

Videos like this are proper helpful

This job was one of those 'favour' requests meaning no mention of payment but i did get paid in lemon meringue pie 😂👍

Hahaha. I've lost count of the number of times that I've tripped over redundant anchor bolts. I usually just cut the buggers flush immediately the piece of kit is removed. There must be some scientific law that states that when being lowered down, say, a drainage shaft, you will bounce off of every anchor stub that some lazy arse has left in place when removin an old access ladder or whatever. If there is one anchor stud in a room 30 metres by 30 metres, you will kick it the first time you enter that room!

I’ve broken the studs flush with the floor by striking them laterally from two opposite directions with a hammer until the snap off.

Thanks, I am going to have to get one of those diamond bits. I have several anchors in the wall in the laundry from an old tumble dryer!

Random Question. Did you appear in the Robot Wars episode of Phoenix Nights?

[keithsnyder]

Dumb question….however, I have a 1/2” anchor that I am assuming is 3-4 inches in the concrete….what size core bit do I need?

[lazylad]

Lost count of the amount of times I've kicked one of these rusty old anchors. Angle grinder problem solved.👍👍

Do you have a video on how to drill these straight into a concrete wall?

I’m trying to hang a wood rack but I’ve tried twice now (I now have 6 concrete anchors stuck in my wall which is why I was watching this video) but if the anchors are even a little not straight I’m unable to mount the wood rack which has three holes so I need three perfectly straight concrete anchors. Any suggestions?

I thought about using a drill guide but idk how I would hold that and use my hammer drill which is pretty heavy even with two hands.

I was able to pry one wall concrete anchor using brute force and WD40. However, for the remaining four anchors. I thought about drilling one or two 5mm holes adjacent to the bolts and it would be easier to pull out. Guess I need more fillers to patch the larger gap.

Good vid, I think I'd choose the cut and punch method .

[benjaminbrewer]

Excellent. Exactly the information I needed.

[jessicabittmann]

What would you fill the hole with after removing the anchor?

[markware]

You have those T shirts available as merch?

[emilyjasperson]

Thanks for the video. I removed an old railing to have it powder coated, and plan to place it back in the same spot. Unfortunately all of the concrete anchors snapped off when loosening due to rust. Can I remove them with a core bit and replace with new anchors in the same spot? Do I need to fill the holes with anything before replacing the anchor in the same spot? Thanks in advance for your advice. I don’t really have room on the stair to move the anchor spots.

What's wrong with countering the nut with another nut and then using it to turn the bolt out?

[BestUserNameUK]

I see you have that Wera ratchet/hammer thing. How do you rate it?

[colinmoore]

I have used an oscillating hand tool to cut off the exposed anchor with good success.

[dougsaunders]

I had never seen core drill method great if you need removal for any reason 👍🏻
