Dave, i have to say thank you for this gem of a worksite. My expirience with chemical cracking is to drill 300-400mil deeper than finished terrain, and waiting at least 3 days, better a whole week. But who's got time for that. Guys figured out the ripper is useless pretty quick 😉. It doesnt take much with a hydraulic hammer to propagate those existing cracks from the breaking agent. Cheers 🍻, you earned that one.
Well Dave, they certainly squeeze those houses tight together in that area. I would imagine this lot was left empty due to the big rocks. Those neighbors are probably thinking they should have left for a month while all the drilling and hammering were going on . Keep up the good work 👍👍
It looks like they were smart 3 ways. 1. They didn't try using a breaker first! 2. They knew you were worth emulating and tried to copy you. 3. When they discovered that you make it look WAY easier than it really is, they called you in to do it! Another smashing success there Dave!
Yeah.. there has been times past when I have let the customer help by drilling some holes, most of them got over the need to help and try saving a $ fairly quickly Ben.
@@demolitiondavedrillandblast I would enjoy drilling a few holes with you, but I am honest with myself that I would probably get over it pretty quickly! I am confident that I am not even as awesome as your daughter... Lol

Dave, I wondered what the fuss was about, so I looked up the contents of the cracking goo. Don't know why it's so expensive, it's mostly calcium oxide, which is cheap and easily available. Trouble is, Calcium oxide sets so fast and so hot that it's actually dangerous- creates steam, and can blow the slug out of the hole with considerable force. So, the admixture is something to slow down the reaction, and make it less temperature sensitive. And there's your trade secret, and the reason the goo is so expensive. Might be worth getting some quicklime and mixing some other things in, see what slows the reaction down.
I hear what you are saying MrLP, most of it comes from China and it is very cheap if you buy a container load. The shelf life is very short though. A company in Canada have been putting in a lot of development work recently and also Neels Lombard in South Africa has recently started making it.
Wow Dave, that was a lot of work. You are a man of convictions. It’s hard, as you know, to work so hard and not expect to see the fruits of your labour for days, or possibly a week.👍👍👍👍👏🏻👏🏻👏🏻👏🏻
Hey Dave, Good to see you back in action. I was very sorry to see all the flooding. I have a friend Cara Bidmead Who lives close to Mt. Lindsey and sent me pictures of the flooding. What a shame from all the Fires to now Flooding. Enjoyed your video as always, Thanks for sharing. I don't know if you remember when I ask you about the noise I kept hearing in one of your video's, Well I found out what it was, Magpie's, Yes Magpie's. Seen them and heard them from another TH-cam site I watch from there.
Howdy Dave, Seriously missed your drilling noise and big booms! At least this job made some drilling noise! Looking forward to part 2 ...... Take care, Stay safe! Jim
Back with a bang! I’m glad I wasn’t paying for that job they looked like real amateurs. It would have been wrapped up in a few days if you were allowed to use explosives.
One good thing I see about the cracking agent is that the removed rock doesn't have micro-cracks like high explosives would leave. This area had a large number of Granite quarries that were ruined when high explosives came along. It was great for removing the Granite but left it with micro fractures that rendered the stone useless.
WoW that is cool stuff! I must admit, at first I was mocking you for wasting all of your time, hard work, and money on that product to split those HUGE and SOLID boulders, but at 12:45 my mouth dropped to the ground in disbelief, but then I was cheering you on!
That broke up real good. Nicely done. It's been too long since some "demolition therapy". Hope all is well with you there. It just switched to spring here in the US Pacific Northwest, which means going the other way there. This vid goes to show the value in hiring an expert in a field vs DIY. You were able to solve the problem in short order using knowledge and experience. I happen to have contractors here at my home remodeling - they're doing in 2 minutes what might take me 10, if I bought similar tools to what they have...and they're doing better quality on the work at that. All around, a good value for me to hire the work out. Looks like the same on this job - the owner / prime contractor would have been money ahead had they just hired you from day 1. But it's there now.
Yeah TC, you are so right TC, with their tired old hire drill, they managed to drill 29m in 3 days and they were really hurting! When I'm working with a helper and we have a drill in peak condition and sharp ballistic button drill heads. I would expect to drill 29m by lunch time provided we get an early start.
This video reminds of breaking a ~5 tons sandstone bolder by hand with sledgehamer, chisels and a crowbar. The construction company got it out of the ground but could not lift it onto a dump truck. The pieces ended up in our garden wall. Since then I have great respect to the old Egyptians.
Holy smokes Dave - horrendous rocks... then, just a ''few'' holes and deep too - love that drill rig. That quantity of "Expando" must have cost a few Bucks! Overall results pretty impressive considering the sheer sizes!. Look fwd to Pt 2 - go have a Fosters! :)
No, this product is no help in tree stumps. Potassium Nitrate rots tree stumps fairly quickly, good old gunpowder is effective at pulling them out of the ground.
In Sudbury Ontario well into the 80s and early 90s developers just gave up having used up all their TNT. Now you buy a house with a bulge of rock formed into the concrete foundation. They made allowance for drainage. Great videos!
Would you have used the cracking agent if the customer hadn't already had it? Seems effective but alot of time. Are the other houses to close for explosives? Maybe I am just partial to stuff getting blown up 🤔
As an old man who lived in Diamond Creek in the late 60's early 70's as a child I remember Sth Morang as nothing but an old pub a tiny shop and acres of nothing but farms 😊
I only recently found out how big it was - main shaft 1000 feet deep and drives running off everywhere. Many interesting mine maps here - www.lydiaheap.com/gold-mine-plans.html#/
I didn't even know such a product existed. But, I do know about expanding foam. I was doing a remodel job and had just installed an expensive glass sliding door. After I left for the day the homeowner decided he'd "help" by spraying expanding foam between the aluminum door jamb and the framing. When I got back in the morning not only would the door not slide open, but the foam had totally wracked the frame and broke the corner joints. He was visibly ill when I told him how much it was going to cost him for me to remove the now worthless door, scrape out all of his foam and install another $1,100 dollar door! People, if you want to help a professional the best thing you can do is nothing and then stay out of his way while doing it!
I don't think I've seen a bloke so rough on a machine! Jeeeezus! A few taps with a rock breaker at all the pressure points first would have saved a ton of wear and tear on the excavator. Great vid!
I came to see how many comments were about the machine bashing I nearly slapped the phone off the ground couldn't watch. Are you short on machine drivers out there ?
*_Dave, where did the Granite Boulders originate from?_* Were they transported by glacier or water and later buried under sediments, or are they what is left from weathered Granite? Their edges look well defined and rounded. It looks like some areas have more Granite than others do. I bet the neighbors appreciate all the care you take to reduce dust while drilling. You are the first one I have seen using a vac collection system to keep rock dust under control. How many meters or other measures do your rock drill bits last? I imagine it depends on the density of rock and diameter of holes. Is there a rule of thumb? What happens to all the broken Granite? Does contractor use it for retaining walls, or is it sold to a quarry who sells it to other contractors? *_Look at the bright side, lots of Granite. You won't run out of work any time soon._*
The current theory is that these lumps broke free by the process of chemical weathering. The Vac system is a game changer! The drill heads last about 30m between sharpening in this rock. The rock has various possible futures.
I like the adapted hand drill (Air Leg), we use them in underground mining still on certain jobs. That size drill is the only option for rocks that size but why no air/water to cool the drill & eject the material? I hope my yard doesn't end up being a job like that.
Hi 007, the drill is an Atlas Copco BBD94 (Panther) It is flushing with plenty of air and all of the material is being ejected but you just can't see any of it because of the high efficiency dust collector. See here - th-cam.com/video/EZNTJ1vyty8/w-d-xo.html
I like watching these type of videos, a couple of questions, what was used before silent pressure came along? And are the granite rocks processed into anything once removed off-site" like in a crusher?"
Plugs and feathers like I use in this video - th-cam.com/video/xIzkQUFCn2k/w-d-xo.html All of the rock that come from this site went to a guy that supplies rocks to landscapers.
awesome !!! that expanding stuff it is expensive? what they do with the granite? it could be used in exterior facades if it were broken into larger pieces and regular shapes, and then cut...
Is it expensive... Expando is AU$160 a 20Kg. box (plus freight). It is ideal for breaking out big pieces to be cut, conversely all of the granite I blast with high explosive is not good for cutting as it is full of stress cracks, granite that has been blasted with black powder is OK though.
Hi dave, love your videos. Its very interesting stuff and you have such a deep knowledge of the work, methods and products. I also live in Victoria and was interested to know how someone might get into this line of work. Is there traditionally an apprenticeship or a course or a traineeship of some variety?
Hi TRM, how do you get into it?? First up you have to love blowing things up and be prepared to do a job that is dirty, noisey, very physical and potentially dangerous. Mining industry is the easiest way in and employs the most blast workers (and pays well). Email me for more details, you can find email address here th-cam.com/users/DemolitionDaveDrillingandBlastingabout
Why did you use the paste? Was it because JMJ had already bought it? I have seen you blast in similarly tight residential spaces before with appropriate earth coverage. Cheers!
Hi Dave, Kinda cool to see you using the cracking agent in such quantity (I only use it in certain small jobs) but why didn't you blast this job ? I've seen you blast in close proximity to houses in the past.
This was the customers preferred method, we did end up doing some blasting on this job when it dragged out a bit. You need to post some video of your work Matty.
Even a very large breaker like this is not very effective on big chunks of Granite, Smaller pieces that are out of the ground can be broken down and anything that has been blasted is full of tiny stress cracks and can usually be broken. A lot of the work it did here was just exploiting the cracks made with the cracking agent.
Have to be careful with vibration limits when the rocks require such deep holes, cracking goo was responsible option. Talked them into using explosives to get the foundations out.
The mix is very critical, if you put too much of the powder and not enough water, apart from not being able to pour it in the holes, it will react too fast and before you know it your mixing bucket is on fire! True!
If you have a look at the tech blerb they quote some force figures. Adusting the mix will cause issues with it going of in the bucket as you mix it or if there is to much water it does not work at all, the best way to regulate the force is by carefully selecting the hole diameter.
Dave, I bet when you drive around and see some rock somewhere in your eyeside you automatically calculate how and when you could blow the sucker up or not. It's the habit of the profession or not?😉
@@demolitiondavedrillandblast no, I am retired. I worked a lot different jobs, last job was sales executive for an exclusive ergonomical office chairs factory. I just enjoy your videos and as always my imagination goes wild and start asking questions, etc. My wife considers me as a harmless professional idiot 🤡🤣
Dang, after you got the new drill bits and started drilling I could see the shaft of the drill bending as you started each hole. While the cracking agent works it is slower than blasting. It also has no impact on the neighboring properties.
@@demolitiondavedrillandblast yup, it's the way to go to ensure no collateral damage. With explosives the vibration can knock a fragile item over in a neighboring property and break it. The collateral damage. :\
Excuse my ignorance please Dave, wouldn't it be quicker and quieter if you were too blast these giant rocks out instead of the method you have to employ in this situation. I know you are in close proximity to nearby residential housing but going by all the demolition experience that you have acquired over the years and this job would be easy for you and completed in half the time. I have watched a number of your videos that you have made and its been a pleasure to watch a master of explosives do his work. Keep up the awesome work Dave and be safe
Thanks for watching Darrel, I was not happy about the vibration level that would be caused by firing blast holes that were 3m deep in a residential setting as they need a lot of bang in them. Also the customer had already purchased the chemical.
holy god, imagine trying to trench a water run at your newly built home and you run into a trillion year old granite chunk the size of a wooly mammoth...
I wish here and a great state of South Carolina in the United States had granite chunks that small when we went into granite here it takes a whole acreage of solid slabs and especially in the downtown area where nobody is allowed to blast we had a grease put in and I spent a month and a half drilling with a giant rig and breaking with the biggest hammer available it's ridiculous
Or build the foundation on Sonotube piers. Raise it up a bit and you don't have to live on top of concrete which is bad for the knees and hips. This just seems like so much trouble... tearing up the Earth just to get a level spot.
Thank you for making these videos. This is a nice escape from the stress in my life. I don't know why breaking rocks is so relaxing.
Glad you like them. AM I find it therapeutic also.

You moved half a mountain here! Wow! Thanks for the video,

Yes, thanks.
Dave, I wondered what the fuss was about, so I looked up the contents of the cracking goo. Don't know why it's so expensive, it's mostly calcium oxide, which is cheap and easily available. Trouble is, Calcium oxide sets so fast and so hot that it's actually dangerous- creates steam, and can blow the slug out of the hole with considerable force. So, the admixture is something to slow down the reaction, and make it less temperature sensitive. And there's your trade secret, and the reason the goo is so expensive. Might be worth getting some quicklime and mixing some other things in, see what slows the reaction down.
I hear what you are saying MrLP, most of it comes from China and it is very cheap if you buy a container load. The shelf life is very short though. A company in Canada have been putting in a lot of development work recently and also Neels Lombard in South Africa has recently started making it.

What happens to all the broken Granite? Does contractor use it for retaining walls, or is it sold to a quarry who sells it to other contractors?
*_Look at the bright side, lots of Granite. You won't run out of work any time soon._*
The current theory is that these lumps broke free by the process of chemical weathering. The Vac system is a game changer! The drill heads last about 30m between sharpening in this rock. The rock has various possible futures.
@@demolitiondavedrillandblast Thanks for feedback
You should number each stone and turn them verticle as polygonal facia stone work..
...chemicals are too quiet...lol...good job, keep safe...
Wow, this job sounds like it must be really frustrating with all the mixed up equipment.
It was a frustrating job.
Reminds me of nippering with the jumbo when u were talking bout the drill bits n the rods.
Nippering... unique underground vocabulary, thanks for watching BigShan.
"Have a crack at it" is a great dad joke lmao, I love it
He hehehe... thanks for tuning in EE
I like the adapted hand drill (Air Leg), we use them in underground mining still on certain jobs. That size drill is the only option for rocks that size but why no air/water to cool the drill & eject the material?
I hope my yard doesn't end up being a job like that.
Hi 007, the drill is an Atlas Copco BBD94 (Panther) It is flushing with plenty of air and all of the material is being ejected but you just can't see any of it because of the high efficiency dust collector. See here - th-cam.com/video/EZNTJ1vyty8/w-d-xo.html
Such a massive amount of granite has been pulled out, and it's not even finished yet.
Great stuff!
👍👍👍👊😎
Thanks George.
I like watching these type of videos, a couple of questions, what was used before silent pressure came along? And are the granite rocks processed into anything once removed off-site" like in a crusher?"
Plugs and feathers like I use in this video - th-cam.com/video/xIzkQUFCn2k/w-d-xo.html All of the rock that come from this site went to a guy that supplies rocks to landscapers.
Would love to see some tests on that stuff... Like weld together a thick steel box, drill a hole in it... Pour, cover the weld and film time lapse.
I could probably do something like that Max, a piece of gal steel water pipe would be easy.
awesome !!! that expanding stuff it is expensive? what they do with the granite? it could be used in exterior facades if it were broken into larger pieces and regular shapes, and then cut...
Is it expensive... Expando is AU$160 a 20Kg. box (plus freight). It is ideal for breaking out big pieces to be cut, conversely all of the granite I blast with high explosive is not good for cutting as it is full of stress cracks, granite that has been blasted with black powder is OK though.
Have you ever watched the videos where the guys do it with chisels and a sledgehammer and they actually have usable pieces.
Awesome Job
Thanks!
Good Video! Keep Em comin Dave !...
Thanks, will do!
20:18, and 20:25 was worth the price of admission.
Something very satisfying about seeing the rock yield.
Hi dave, love your videos. Its very interesting stuff and you have such a deep knowledge of the work, methods and products.
I also live in Victoria and was interested to know how someone might get into this line of work.
Is there traditionally an apprenticeship or a course or a traineeship of some variety?
Hi TRM, how do you get into it?? First up you have to love blowing things up and be prepared to do a job that is dirty, noisey, very physical and potentially dangerous. Mining industry is the easiest way in and employs the most blast workers (and pays well). Email me for more details, you can find email address here th-cam.com/users/DemolitionDaveDrillingandBlastingabout
Why did you use the paste? Was it because JMJ had already bought it? I have seen you blast in similarly tight residential spaces before with appropriate earth coverage. Cheers!
I was contracted to drill holes Dan, ended up doing a whole lot more.
imagine the effort of building the pyramids in the context of getting rid off these little stones with insane heavy duty technology
Yeah... something to think about.
Hi Dave, Kinda cool to see you using the cracking agent in such quantity (I only use it in certain small jobs) but why didn't you blast this job ? I've seen you blast in close proximity to houses in the past.
This was the customers preferred method, we did end up doing some blasting on this job when it dragged out a bit. You need to post some video of your work Matty.
Very interesting. Could the breaker attachment used toward the end break up the original boulders without the cracking agent?
Even a very large breaker like this is not very effective on big chunks of Granite, Smaller pieces that are out of the ground can be broken down and anything that has been blasted is full of tiny stress cracks and can usually be broken. A lot of the work it did here was just exploiting the cracks made with the cracking agent.
@@demolitiondavedrillandblast Thank you, I appreciate the response.
If they had not already purchased the cracking goo would you have used explosives on this job?
Have to be careful with vibration limits when the rocks require such deep holes, cracking goo was responsible option. Talked them into using explosives to get the foundations out.
Doctor Stone just used plaster. Neat stuff!
There is not enough soil-there is a lot of granite-you will never be left without work
When a job needs doing properly call Demolition Dave :) poor Hitachi is all I can say !
I had to sensor some scenes David.. the old Hitachi got a flogging!
@@demolitiondavedrillandblast Probably no grease as make-up present either. :)
@@demolitiondavedrillandblast she needs therapy for some of that abuse 😂😂😂
I saw a fair few videos on youtube on how to do stuff. Good thing they called you before they got you into a big mess.
I hear you Chris, this job had trouble written all over it!
what would happen if you mixed more of the ("expanding stuff" you put in the holes) in the cracks wouldn't that speed up the cracking?
The mix is very critical, if you put too much of the powder and not enough water, apart from not being able to pour it in the holes, it will react too fast and before you know it your mixing bucket is on fire! True!
@@demolitiondavedrillandblast interesting! i feel asleep in science class to much. now im the guy who moves the rock after your done lol
that poor excavator with the ripper🤣
Oh yeah...
How much pressure per mm2 does this chemical work to and can you adjust the mix to make it change the force?
If you have a look at the tech blerb they quote some force figures. Adusting the mix will cause issues with it going of in the bucket as you mix it or if there is to much water it does not work at all, the best way to regulate the force is by carefully selecting the hole diameter.

Ευχαριστώ που παρακολουθήσατε.
Dave, I bet when you drive around and see some rock somewhere in your eyeside you automatically calculate how and when you could blow the sucker up or not. It's the habit of the profession or not?😉
Hahahhahah... Now I know for sure that you and I work in the same profession.
@@demolitiondavedrillandblast no, I am retired. I worked a lot different jobs, last job was sales executive for an exclusive ergonomical office chairs factory. I just enjoy your videos and as always my imagination goes wild and start asking questions, etc. My wife considers me as a harmless professional idiot 🤡🤣
Dang, after you got the new drill bits and started drilling I could see the shaft of the drill bending as you started each hole.
While the cracking agent works it is slower than blasting. It also has no impact on the neighboring properties.
It is "snail blasting" Jaqui.
@@demolitiondavedrillandblast yup, it's the way to go to ensure no collateral damage. With explosives the vibration can knock a fragile item over in a neighboring property and break it. The collateral damage. :\
Excuse my ignorance please Dave, wouldn't it be quicker and quieter if you were too blast these giant rocks out instead of the method you have to employ in this situation. I know you are in close proximity to nearby residential housing but going by all the demolition experience that you have acquired over the years and this job would be easy for you and completed in half the time. I have watched a number of your videos that you have made and its been a pleasure to watch a master of explosives do his work. Keep up the awesome work Dave and be safe
Thanks for watching Darrel, I was not happy about the vibration level that would be caused by firing blast holes that were 3m deep in a residential setting as they need a lot of bang in them. Also the customer had already purchased the chemical.
Very cool video
Glad you enjoyed it, thanks for dropping in, lots of similar videos on this channel.
holy god, imagine trying to trench a water run at your newly built home and you run into a trillion year old granite chunk the size of a wooly mammoth...
Yes, it can be very challenging stuff to work with Jake
Great job, thank you for sharing
Thanks for watching JJ.
did you see part 2?
As you can never know how deep a rock is, what happens to Expando or explosives if you drill right through it?
In both cases you just back fill the hole a little.
Damn what a satisfying job lol
"Snail Dynamite" in action.
Seems to me that blasting is still the fastest, most cost effective way to get this stuff done.
Oh yeah, by a large margin David.
I wish here and a great state of South Carolina in the United States had granite chunks that small when we went into granite here it takes a whole acreage of solid slabs and especially in the downtown area where nobody is allowed to blast we had a grease put in and I spent a month and a half drilling with a giant rig and breaking with the biggest hammer available it's ridiculous
Sounds like some explosives would have really helped Kevin.
And that's how you crack excavator booms...
Yeah and not just that, I have actually seen an old and very fatigued boom snap of and fall on the ground.
Poor people next door.
BTW, Good Job...
i think everybody on the high side of this street had lots of rock and they knew the deal.
A joy to behold. 🙂
Indeed Craig.
Or build the foundation on Sonotube piers. Raise it up a bit and you don't have to live on top of concrete which is bad for the knees and hips. This just seems like so much trouble... tearing up the Earth just to get a level spot.
I hear you my friend, so many times I have to remove really good hard granite only to put concrete in its place.
