Breaking concrete with pickaxe + chemicals
< on 1/21/2015 7:43 AM >

Posted on Forum: UER Forum
I have a project in mind that requires breaking small blocks of concrete to access a location. I won't be able to get a car or power cables near the location, so I'm trying to avoid using power tools as much as I can, but I have heard about concrete dissolver chemicals that may help. Do you think that using a concrete dissolver and a small hand pickaxe can be used to break concrete by a significant amount, or is this totally unrealistic? I've tried with the pickaxe without chemicals, and it doesn't work at all. Does anyone have tried that before?

Here is a picture of one of the concrete blocks that I want to cut off, so you can get a sense of scale.

Anything that could probably dissolve concrete would probably create some pretty harsh breathing conditions, especially in an enclosed space.

First off, as Steed said, you'd require some pretty harsh chemicals to do that, which will create an unsafe work space.

Secondly, what you are asking sounds an awful lot like breaking and entering. We all want to see some awesome locations, but I am sure no one will publicly provide you information that could result in legal action against you, themselves, or this website.

So much of this. But it's a moot point. You can't really dissolve concrete; those concrete dissolvers are more for removing excess concrete from tools and other surfaces. Properly formed concrete is going to be much harder to get through in that case... you'll be pretty much doing most of the work with the pickaxe.

Try and find another way in.

The space is not really enclosed, I'm trying to dig from an outdoor field.

I understand your concerns, but these blocks of concrete are buried under a pile of dirt, so I doubt anyone will notice if I put the dirt back on. I don't think I will even have to break through a wall, I just need to change the shape of these concrete blocks to squeeze myself between. It's not like I'm trying to bust somebody's front door, I guess...

That's what I was thinking, thanks for the info.

I won't be the first either, some people on UER have already been there more than a year ago, there is even an entire archived public thread about this location.

Anyways, I'll be patient if it's too hard, somebody will maybe come up with a better way to get in.

Maybe keeping this public might not be the best way to ask ;) I'll PM you.

Legality and health issues aside, as has already been pointed out, properly formed and cured concrete cannot be chemically dissolved. If anything it only gets harder and stronger with age, and that doesn't look new.

My other thought was that even if you could soften it to the point where it could be broken with a pick axe, any internal rebar would still prove a tangled mess to get through. Having seen the photo it doesn't look like a coherently poured slab of reinforced concrete and more a crudely poured pile. Then again I've had to break up crudely poured piles of concrete a few weeks after they were dumped (sloppy work not cleaned up by lazy contractors pouring the foundation at our cottage) and it was NOT at all easy or pleasant, even with 25lb sledge hammers and full sized pick axes. Took like half a day of miserable work to break up the pieces. Not fun.

Under different circumstances I'd suggest a pneumatic sledge hammer, but that's REALLY vandalism / B&E, not to mention rather impractical.

I knew you would recognize it! And yes, I don't know how much concrete is left behind, I wasn't there a few years ago when they didn't have all these blocks (or did they?), so I don't have a good sense of scale. The echo of my voice through the small hole kept my hopes alive... until now.

Well, back to realistic explorations.

I personally have not been back to this specific hill in about a year +

If these blocks were to magically become passable at some point in the future I would be all over the opportunity to go back inside this location.

Honestly it would be easier and more time effective to bypass the blocks by digging another tunnel connecting to the ladder that takes you down. Tunneling comes with huge risk of collapse and death. I do not advise it.





edit: September 2012 the last time I bothered to drive up there. location was purposefully dug out, exposed to all eyes, stuffed with concrete blocks, rebar ladder was cut and dropped to the floor, location was buried, left as photo shows.

Pickaxe and rent a gas powered concrete saw from home depot or possibly a 10-15lb co2 tank running an air hammer which is pretty small actually. then from what the post above looks like a hammer drill to drill some rappel points

Although I believe we're at this point all speaking hypothetically, I just wanted to give a friendly reminder to please refrain from discussing specifics relating to Breaking & Entering.

We'll definitely keep this discussion going, but just keep that in mind and act accordingly.

This is the kind of thread that shows up on government radar and puts us all on some sort of list, especially considering it's public. -.-

I understand, I won't make a scandal if you decide to delete this thread. It looks like what I asked for is out of reach anyway.

Sure it's public, but I hope that my picture is vague enough that only a handful of people could guess where it is. This location appears in other threads online, but people who haven't been there could not recognize it with certainty from my picture only.
I agree it's good to be careful about this kind of things, but saying that a random dude asking how to break harmless blocks of buried concrete in an unknown location is worth the government's attention is kind of a stretch. I have never been on a government's watchlist (not that I'm aware of), so I don't really know what it feels like and maybe I'm underestimating it, but I still feel like this thread itself is not worth worrying about. As I said, if it bothers too many people, I'm OK for letting the mods deleting it.

You people crack me up with the breaking and entering warnings


if you walk into an abandoned building through a doorway that is wide open, with not a single tool in your pocket, in most states is breaking and entering ... don't kid yourselves..




as for the concrete. the effort from what I see in your pictures, is more than likely not worth the final payoff.... i'd leave it.

I agree it's a somewhat moot point to argue legal ethics on a forum devoted to casual trespassing, however in Ontario anyway there *IS* a legal distinction between "Breaking & Entering" and "trespassing". One is a criminal charge while the other is a $65 provincial infraction (same category as a speeding ticket).

Generally speaking, the main factor used by police to determine which charge to lay is the presence of burglary tools, hence the warning to please not discuss using concrete saws and the like. Of course this will vary by state/province/municipality/country, but as a matter of practice we don't want to condone or encourage the vandalism of locations.

That being said, as has already been pointed out, the location is not at all obvious, and at this point I think we're just talking about varying methods with which to destroy concrete.
