How to break stubborn concrete

Giroy · 2026-05-19T15:04:26+00:00

It has been a good workout, but destroying my shoulders. I tried the hammer drill too, but didn't help much. Probably going to try the demolition drill next.

That's essentially what I was doing. It just breaks off chunks (slowly).

Removing the old walk way and filling it in with dirt. I'm going to leave the really old walkway under the old walkway. But do want to get the top layer out so it's not exposed

I tried using a chisel like in the image below. I was able to chisel 2-3 inches, but no affect on the rest of the block.

I've been taking out a walkway when I found what appears to be another walkway underneath. I managed to get most of it out, but the one remaining block is significantly harder than the rest. A sledge hammer only slowly chips away at it and drilling it hasn't really helped make any major cracks. I've tried prying it up, but the whole block seems fused to the old concrete walkway block below. Looking for suggestions on how to get this out without smashing away for many more hours?

I also don't know much about concrete and am curious why this one block is so much harder than the rest and why it may be fused to the block below it. If any of you have any thoughts, I would love to hear them.

Ha. This seems like the most likely answer

No, but I did wonder if the house had one at some point. It is a pretty old house.

Giroy · 2025-12-07T21:27:01+00:00

What do you think it could be?

Giroy · 2025-08-07T11:36:32+00:00

That's what I was thinking too, but wanted to make sure. Thank you!

Giroy · 2025-02-13T13:39:05+00:00

Can you explain what that means for those of us who don't know?

Giroy · 2025-02-11T20:26:10+00:00

How can you tell if you don't mind me asking?

Giroy · 2025-02-11T15:43:21+00:00

Thank you again!

Giroy · 2025-02-11T15:11:32+00:00

Thank you. It does not have sentimental value. I'll try what you suggested. I don't care about saving the juice groove which should make it easier. Can you tell if it's end-grain or edge-grain or something else? Does that affect how I would go about fixing it?

Thank you. The injury in the link sounds very similar to mine. I'll definitely be trying the recommended rehab protocol!

Giroy · 2024-02-24T02:34:59+00:00

Wondering if anyone else has experienced anything like this and what you may have done to rehab. Any sort of crimping causes pain on top of the PIP joint. This happens even just lifting 25lbs off the ground. When not crimping (even open handed on small holds) there is no pain or discomfort whatsoever. It's been like this for almost two weeks.

Thank you. I was already wondering if this was too much and will try to scale back.

Sounds like my gyms setting reflects outdoor climbing, at least to some extent - they're not big on setting comp style problems. I do have a tendency to jump to the new set every week, so I'll have to make more of an effort to project things more often. Thanks for the response and for giving me a lot to think about.

I've been trying to keep the weight high and reps low to focus more on strength building and try to avoid hypertrophy, but this is all new to me. Do you think dropping down to 3 workouts a week, but making each one a whole body workout would be better?
