Hi Dave, Your miscalculation 'fix' turned out superb! Amazing how that small hole was all the ripper tooth needed to bring it all down! You guys work together so well! On to the next job! Take Care, Jim
For sure David, the breaker is really challenged in this rock, however after some blasting or cracking agent work the breaker can get a lot more material out.
Working tight on this one. You know, the better you get at these tough, dastardly, jobs, the more people will go out of their way to give 'em to ya. It'll become sport for the builders -- "Har-har-harrr, let's see if Dave can get this one out after we put up the framing". Very nice camera work on this one as well. Perfect slow-motion shots. Take care, Sir, and thank you for sharing this!
Thanks for watching Ian, the slo-mo camera does not record slow sound and the normal speed sound recording is average quality, so I use the sound from my Sony Handycam and time stretch it to match the slo-mo footage.
I liked that they tried to use the expanding compound, it didn't work and they called you in. Not sure how much you charge but it must be worth it. Thanks for posting.
Amazing, thank you! I’m going to try some cracking agent this summer. We have a granite boulder in the way of a shed build. Thanks for introducing me to this in some of your past videos.
I had one of these hydraulic hammers working in my neighborhood, for a month. Couldn't stand the hammering noise all day. I moved in with my daughter and her family until the job was done.
i was thinking ya mate needed to go into one of the cracking holes right at the end, then you jumped down to clear one out. i must be learning something Dave. a brilliant result with the end result, that would make a great section on view, what a shame it will be covered up.
Nice to see you, Dave. I was thinking about you the other week and wondering how you have been. I know how the work goes, slow for a while and then things just explode on you. keep safe, thanks for the videos.
I hear you 100% Daniel, I have trained lots of people to a greater or lesser extent, few people though want to do a really dirty physical and often difficult, possibly dangerous job.
@@demolitiondavedrillandblast Most welcome! Those last stones look like the ones in the woods in Pennsylvania. They used wedges back in the day to split the rocks to make big blocks to use in building keystone bridges
Hey Dave; have you ever done any UA-cam shorts ? I’m sure a few UA-cam shorts of just the “20 holes, echelon pattern, Big Bang” would be super popular. Also you could do a series of short short videos on some of the really interesting things that you have pulled out of the Australian outback while taking away rocks. They only need to be five minutes long and each one dedicated to one piece of history. And do them as a series. I hope you don’t mind me sharing some ideas for your channel. Super thank you as always sir for the great videos. 🥰
*_Dave, do you use delays on your live shots to minimize ground vibrations?_* You do such a good job covering rock to be blasted with backfill. That certainly reduces the sounds and flying rock frags. The energy pulse travels through ground fairly quickly and it can travel quite far. Neighbors might not hear the shot, but their shaking windows and dishes rattling in cupboards is hard to disguise. *_I know on big quarry shots delays reduce ground movement. Same with implosions._*
Now that the lot is ready there is no money left to build the house, and the bank won't finance any more than a normal build minus some owner equity. LOL! But then that's not Dave's problem either. Nice job! I learned a lot. That chemical stuff is amazing and you must have a ton in just that air compressor and drilling equipment and some pretty good material expenses with those bits.
The packaged emulsion explosive is Orica Senatel Magnum - www.orica.com/products-services/packaged-explosives/senatel-magnum#.Y5bAqn1BzIU Thanks for watching.
I need an extra truck to transport a load of them, they are very high maintenance and if you have a very large rock, you have to take several bites at it when it is best (from a complaint perspective) to get it all over and done in one shot if you can. The soil also does a much better job of managing the noise and it is already at the job. Post some video Martin.
Yes handling them sometimes is a struggle. I work for the city so the budget and a truck to move them is not a problem. 99% of the blasting i do is in a trench with water an sewer pipes just next to the blast. So using rubber matts is the only option. I will try to film sometime.
looks like you could have popped that last slab loose with a 2 or 2-1/2 meter wrecking bar Dave! nice cover lift on most of those!! i'm still amazed people settle for lots that size! a lot that size is a damn fire hazard the house next door goes up your's is likely to go too (not to mention not having any front or back yard for recreation and relaxing in!)! hell if the winds right the entire block could go!!
@@demolitiondavedrillandblast still from the look of how it was sitting it looked like it could tipped over with a bar easy enough! it may have just been the filing angle though!
@@demolitiondavedrillandblast Dave, it was just an observation on how it looked nothing more! basically thinking out loud so to say! i will say this though going by what you've posted already you won;t run out of work anytime soon!!
I didn't realize the scale of that last slice of bread until you jumped down on the ledge to clear the hole, and it looked like a sidewalk! Lol It looks like the boom butter works on that type of rock a little better than the slo-mo exploding goo.
Leaving the face of the big rock exposed would be a cool feature in the new house. Thanks for sharing. Dave, did this job take longer using the chemical agent rather than blasting all the rock?
You managed to convince them explosives were perfectly OK on most of the site then? I'm thinking it would've taken a lot of cracking goo & time to do the same job.
Mmmmm... no, not in the rock I work in, which is mostly Granodorite, not strictly Granite. It is common to find intrusions of quartz or hornfelds and sometimes black zenoliths which are very hard - probably hornfelds.
@@demolitiondavedrillandblast my local batholith is also granodiorite and it has a lot of pegmatites. Interesting. I wonder if it was because they formed at different depths. I think pegmatites only occur when the magma cools somewhat close to the surface.
Awesome break Dave. Can you do a short video on rules and regs on blasting for us noobs? Like difference between urban and rural. And other things we might not know :). Keep up the good cracking and abs blasting
@@demolitiondavedrillandblast Is there not a case to be made in terrain like this to simply add 2m of soil over the whole plot? Are there council/homeowners regulations that prohibit a house on (soil) stilts so to speak? All you really need is space to park the car at street level.
@@KallePihlajasaari Moving lots of soil is expensive too, as would the retaining walls to hold it back, and then you'll have an extra two meters to climb every time you wanted to park your car or get into your house. Plus then you'd need to worry about maintaining the retaining walls, and the house would look silly being raised up like that. I imagine it's much cheaper both long- and short-term to just get rid of the rocks.
I pity the future homeowners when they try to dig for a garden. I live about 0.8 km from an open pit rock mine and I cannot sink a shovel in my front yard without hitting half a dozen rocks. I've had to resort raised gardens.
I wonder where they take several dozen tons of "gently used" granite boulders to get rid of them, so they aren't taking up space on the build site anymore
Almost wish that last rock wall you exposed could be incorporated as a permanent testament as to what it took to build the house.
Yes William.... most of my best work is behind retaining walls and under concrete, such is life.
Yeah. Would make an awesome testament wall’.
At least maybe use those square columns as landscaping elements
Unfortunately, the ‘testament wall’ idea would probably not be allowed from an engineering standpoint, as they might be concerned about the rock’s structure after cracking.
Just going through your old videos and really enjoying them and let me say nobody could criticise your work. Keep safe.
I appreciate your kind words. I'm still learning after 32 years!
A great photo (that rock wall you made) for the new building owners to keep as history for "making things possible." Good to see you smile, Dave!
Glad you enjoyed it... All of my best work is behind retaining walls and under concrete JW.
Nicely done. Love how that last part came apart so cleanly and in such large pieces. And it made for a fine thumbnail.
Glad you liked it TC.
Hi Dave, Your miscalculation 'fix' turned out superb! Amazing how that small hole was all the ripper tooth needed to bring it all down! You guys work together so well! On to the next job! Take Care, Jim
Glad you enjoyed it 531... Not my miss calc... hahhaah, I see it so often.
Thanks Dave. Your work sure saves the breaker machines.
For sure David, the breaker is really challenged in this rock, however after some blasting or cracking agent work the breaker can get a lot more material out.
Dave I could only imagine how much information you must stored in your head to achieve the work you do!!
Probably not that much.
Working tight on this one. You know, the better you get at these tough, dastardly, jobs, the more people will go out of their way to give 'em to ya. It'll become sport for the builders -- "Har-har-harrr, let's see if Dave can get this one out after we put up the framing".
Very nice camera work on this one as well. Perfect slow-motion shots. Take care, Sir, and thank you for sharing this!
Thanks for watching 42
Skill and teamwork Dave - way to go. Local geology keeps you in business, and that site was just loaded with rock.
Heaps of the stuff Chris.
I find your videos fascinating to watch, Dave. I love the sound of the explosions in slo-mo !
Thanks for watching Ian, the slo-mo camera does not record slow sound and the normal speed sound recording is average quality, so I use the sound from my Sony Handycam and time stretch it to match the slo-mo footage.
I liked that they tried to use the expanding compound, it didn't work and they called you in. Not sure how much you charge but it must be worth it. Thanks for posting.
They "gave it a crack" but under estimated the difficulty of the drilling. Thanks for watching Robert.
that was such a nice clean cut
The Cracking Agent is good for that.
That cracking agent is pretty cool stuff. I liked the way those blocks of granite came out at the end of the video.
Yeah, its great stuff for cutting out big blocks Jim.
Amazing, thank you!
I’m going to try some cracking agent this summer. We have a granite boulder in the way of a shed build. Thanks for introducing me to this in some of your past videos.
Good luck! Make sure you drill the holes large enough diameter and plenty deep.
Nice work Dave. Good to see that you are keeping busy.
Mark from Melbourne
Yes, thanks
You are a true professional Dave! Thanks a lot for yet another super cool vidja
My pleasure!
That is a beautiful break at the end! Nicely drilled, nicely executed!
Thank you very much, I hope that it is exposed for everybody to see and not behind a retaining wall.
You are the man,Dave. Excellent work.
Thank you kindly.
Well done Dave nice work. Great machine operator.
Thanks 👍, I had 4 different operators on this job... not what I need.
The amount of energy release during those explosions its incredibly amazing , great job as always .. Sir you're a Pro doing what you do , thx Dave
Thanks, and thanks for watching Jose.
Intro music was a BLAST ! 🎸🤘 🎵
The rock master at his best. Congratulations!
Thanks Craig!
Nice work Dave
Thanks James. More Granite busting action as soon as I can find some time to cut video.
It amazes me how well the soil covering the blast suppresses the smoke from the blast.
And the noise!
Very nice logo, well done Dave.
Thank you kindly Chris.
That is a nice cut on the granite . I would use that in the design of the house or grounds .
Be nice but it will just be behind a retaining wall like most of my work.
Another great video Dave .
Glad you like them William.
Stubborn big rocks but Dave cracked them. Great job.😎
Very stubborn these ones Arie.
Excellent vid Dave.
Thanks 71
More great stuff Dave 👍👍👍

Is there a big difference in price for tyke coustomer if you are Blasting or using the cracking stuff?
The Chemical is not too expensive but the extra drilling is very costly.
Always great music.
Thanks, I agonize over the music choice.
Nice one dave !
Glad you enjoyed it Tim, more video coming soon.
amazing how straight the split is , great work 😇
Thanks.
Why don't you use the big mats when blasting in the residential areas? They are used to stop fragments of rock flying around right?
Yes they do, but they do little to manage the blast noise - which is what brings complaints.
What gorgeous work. I hope you have trained some apprentices, we have to teach the next generation best practices.
I hear you 100% Daniel, I have trained lots of people to a greater or lesser extent, few people though want to do a really dirty physical and often difficult, possibly dangerous job.

I've not really though about shorts as I have an aversion to portrait style video, that shorts must be. It just seems all wrong to me.
Shorts do hurt the UA-cam algorithm I've been told to stay away from shorts only if your making like an channel introduction.
@@demolitiondavedrillandblast Agreed. Portrait style videos are crap.
A couple of those monoliths would make a robust garden feature, almost enough parts for a DIY Stonehenge.
Yes, all of this rock went to a guy that sells rock to people who do landscaping.
Admire your work but my sympathy is for the two neigbouring home owners.
They were really good - they had gone though similar pain with their builds.
Good fences make good neighbors. You can't get a more solid fencing material than that strip of solid granite between the houses.
That's not a house lot, it's a quarry!
Those last slabs came out beautifully.
Almost... There is actually a quarry just over the hill from here - no surprise.
*_Dave, do you use delays on your live shots to minimize ground vibrations?_*
You do such a good job covering rock to be blasted with backfill. That certainly reduces the sounds and flying rock frags. The energy pulse travels through ground fairly quickly and it can travel quite far. Neighbors might not hear the shot, but their shaking windows and dishes rattling in cupboards is hard to disguise.
*_I know on big quarry shots delays reduce ground movement. Same with implosions._*
I always use one hole per delay period on domestic jobs.
@@demolitiondavedrillandblast thanks for reply
Dave what happens to all the busted rock it must be hauled away, is it used in someway?
Not often that it gets wasted, sometimes used in Landscaping, sometimes goes to a crusher. etc.
What chemical you use to breaking hard rock....
Expando - expando.com.au/
When do you choose chemical cracking over explosives? I guessed in part 1 you couldn't use explosives due to the other nearby homes.
Initially it was the customers call, they were fairly concerned with the idea of using bangers, I talked them into it later in the job.
Which camical u are use..this available in all Nation...
There are many different brands of this product available in many countries. What country are you in?

Nice!!!!! ( was the rock much harder in this area...?)
Yes it was, plenty of good hard Granite here and some soft stuff.
I suspect that the neighbors will be pleased when you have finished. Then the builders move in.
I'm sure!

Nice job! I learned a lot. That chemical stuff is amazing and you must have a ton in just that air compressor and drilling equipment and some pretty good material expenses with those bits.
I'm not sure about the financial logistics of the build Jack. Yes, there is a big outlay on tools and big wear and tear in this line of work.
What do you all do with all that granite?
I gave it all to Transrock - www.transrock.com.au/?loaded
I could watch that hammer all day!
Thanks for sharing 🇨🇦
Glad you enjoyed it Paul.
that digger rattles like it's dying! It seriously needs some attention to the pins and couplers to tighten them back up.

is that a neighborhood?
sure is Tim.
Amazing how they put up such a fight. Is that the hardest type of rock you deal with?
Probably the second hardest rock that I have to deal with, Rhyodacite is considerably harder.
Hi. How come you dont use rubber matts? Just interested in how you work, here in Sweden we always use rubber matts when we cover. Good content 👍

Nice piece o' work! It took more than one way to skin the cat, but skinned it was...
Thank you! Cheers!
Neighbors got to be so happy.
They were good, spoke with them often and as they had been through similar trials the were very understanding.
You could probably get some good dimensional stone out of that breakage with a diamond saw!
The rock that has been split wit the cracking agent is good for dimension stone, the blasted rock is useless as it is full of stress cracks.
I would have liked something made out of the rock for the house, maybe a countertop.
Oh yeah, If I had a diamond wire saw I could have cut some big slabs out of this site!
Might I suggest using "Men at Work" as your background music?
Can't do that as it would be immediately canned for a copyright breach.
What do your vibration levels look like on those shots? I see very tight pattern, so assuming your charge weight per delay is quite low.
The vibration is minimal, most of these holes have only 60grams in each hole (1/3 of a 1 1/4" plug).
Awesome break Dave. Can you do a short video on rules and regs on blasting for us noobs? Like difference between urban and rural. And other things we might not know :). Keep up the good cracking and abs blasting
