- The young couple had just started construction of their first home when they found this, 4 massive pieces of Granite that were not going to move for anyone, too big to dig and too hard to break... This was a real problem. The quick thinking young man scoured the net and found Demolition Dave, Dave was out there for an inspection the next day. An explosive solution was discussed and implemented over the next Two days, problem solved, another happy customer, project back on track.

very, very neat work: nothing flew out of the pit during the explosion, but the stones split into small pieces! wonderful! fabulous! amazing!
Thanks for watching DA
My uncle paid 10k a rock to get these placed on his yard
I don't know why it always makes me grin me when you hook your leg over the drill and ride it down like you were at an amusement park. Have to say that was a energetic pop on the first blast.
Certainly was, had to be so the pieces would be small enough for the small machine to dig out.
@@demolitiondavedrillandblast We don't usually see so many fragments escape the dirt cover after the blast, but we didn't see and smaller chunks flying so no worries.
Looks just like our garden in Yealmpton, Devon, UK. The housebuilder went bust in the 1970s because of the costs of shifting huge rocks like this from the land.
You certainly work hard for your money Dave! On top of that you’re putting it out on CZcams. Thanks
Thanks David.
Work hard? He's only had to work for less than 15 minutes ;-)
Prolly ain’t cheap is ol’ Dave I reckon
@@mikemclennan8917 You ever try using a rock drill, especially in hard granite like this?
@@demolitiondavedrillandblast what do you calll the guide piece you use for the drill. looks like its worth its weight in gold as far as stabilizing the drill.
As always - a great job! At the time of my comment, you had 814 positive comments and 5 negative comments! What the hell can be negative? Brilliant work and for those that don't think so keep quiet. Keep up the good work.
Thanks Roger, I always get 1 or 2 in the first Hour as sour grapes from local competitors, 3 of those 5 are in the last few hours... CZcams must have started promoting the video to the rock huggers.
That loose soil really makes a good blast mat. Thanks Dave. I am sure enjoying the videos and views of your beautyfull Australia.
Thanks again David.
cheers again Mr D for sharing this with us -please stay safe and well sending regards xxx
Thank you MLE
Wow, that blast was spectacularly, unspectacular...really well controlled! 😎
EDIT: Just watched that digger plucking the rock from the soil like a huge mechanical bird...very cool.
Thanks for watching and contributing Mark.
This is one of the coolest videos especially the editing. Thanks
Glad you liked it! Thanks for watching.
Amazing how well that dust collection system you got works 👌
I love it, It works real well. I think the vac made in your part of the world.
A Vac *and* a mask, no silicosis for you!
@@cetyl2626 Actually it looks like the mask is for the exhaust from the drill, the vac would make it virtually dustless.imho
That was a little more energetic than average. Love the videos!
Yeah, big rock, small machine, high load rate.
When they are dug out like those rocks, they look bigger. Nice video. looking forward to the next one. Cheers!
They were big ones, next video will be soon David.
Well the algorithm brought Dave around again.
Good, you are allowed to check in more often Eli.
Always a pleasure to watch your level of skill
Thanks Brian.
I didn’t expect the short end of the first blast to throw as much dirt as it did, looked buried same as the rest. Good stuff again thanks!
I always she'd a tear when they bury them.
It was light on for cover as we were running out of easy to reach soil... I did move my Hilux a bit further away for this one as it was only 1 meter on the other side of the fence, all good though as nothing went over the fence.
271👍's up demolition Dave thank you a lot for taking us all along with you to see how you do it down under
My pleasure
Thanks man. That was so perfect
Glad you liked it!
Dave, you are the man.
✔✔✔ Both the punter and the builder would have to be delighted with that outcome .. Bravo !!!
Yes, all good there now.
Top work as always.
Appreciate that. Thanks for watching
I wish America would adopt an approach to clearing sites using your kind of practices
They do PA, I follow the activities of several companies in the USA that do exactly as I do.
Well when the house is finished the lady of the house can have a rock garden. Good job
Polish it up and she can have a nice kitchen worktop too!
That's what I'd do
You are the man 👍👍awesome Dave.
Thanks Bob.
That was great! Cool video work.👍👍👍👍👏🏻👏🏻👏🏻👏🏻👏🏻
Thank you very much Grumpy, thanks for tuning in again.
Wow. I guess these folks really wanted a house with a basement!
Yep.
With chunks like that just under the surface, I've a feeling you'll be heading back to that area a few times.
Done a lot in this area over the years Mikey.
Oh man, Diorite near a house? Bang up job mate.
Yeah, it is hard stuff but we have the right medicine. Thanks for watching Bill.
job well done, Dave! 👍👍👊👊
Thanks JW
I am so jealous of you sir all jobs get all at one point but never blowing shit up .
That first one was a fair dinkum kaboom. Thanks for another great video.
Yes it was, was not at all loud though Deane.
Looks like *Australia* is the place to be if you want to build a garage with a /very/ solid base to pour a concrete plinth for a really nice engine lathe. Thank you for taking us along on your adventures!
NZ, NZ... Wash your mouth out Jim, I'm in Australia... Heheheheh. Thanks for watching.
@@demolitiondavedrillandblast Awwwww dang. Where's my head? Sorry.
,,,gotta love the net..lol..good job, keep safe..
Thanks Bob.
After 4 months of not being notified of your videos, they are back.
That is really interesting that you say this Michael, other people with a similar ideological profile to myself have also noticed this. All my recent videos can be found here - czcams.com/users/DemolitionDaveDrillingandBlastingvideos
The small size of the excavators I see on your job is always somewhat of a surprise. I'm from Canada. Theses small excavators are mostly relegated to jobs where there is site access restrictions, foundations repairs and landscaping. Any new construction would be done using a much larger machine. I guess that with the short building season, size does matter for expediency's sake. It is also true that the holes we dig tend to be deeper as we do need to get under the frost line.
These mini excavators are taking over . Everyone and their mother has one down here in tx
We need bigger machines to break through frost and extend our season. That little excavator also is cheaper to move around. Cheaper for truck and trailer plates. Also oversize fees and weights.
Awesome thank you
Thanks for watching 123
Among all the possible unplanned expenses you could incur, that one would suck really badly.
Yeah, especially when the soil test says no rock like this one. Good thing that I'm cheap.
"might have been a tad heavy handed", combined with a mildly uncontained shot 1, great shatter and great bulking of the material earns this an 8 out of 10 on the patented TC's "That blowed up real good" rating scale. Nicely done.
He hehehe...
My dad was a land surveyor up North.
Once he blew up a beaver dam using three sticks of dynamite super instructions.
However the person who said three sticks meant 6 inch 1/4" diameter 40% power sticks. Dad got three sticks from the road crew that was blasting rocks. Those sticks were 18" 1/2" diameter 80% power.
He blew that dam down to bedrock.
Another great job, Dave :) Happy landscapers and masons but nervous cameras :P
They are, and they have good reason to be!
Imagine you're the customer and they uncover those boulders? I'd be pretty dismayed.
Oh yeah! He was very relieved to see them disappear.
Good one! 👍 Would be interesting if those rocks could talk. How and where they formed and how they came to be there. Little did they know what fate would befall them! 🤔
We had to excavate around 200m³ of granite for our house. (Blackwood forest)
Luckily only 1/4 was really hard, but it took around 1 week to Chisel that out with the big excavator.
Using detonations isn't easy anymore, you need a specialist, a lot of paperwork, evacuating half of the town...
You were lucky that the big excavator was able to manage it! Thanks for watching.
Ah. You found Jack and the bean stalk's potatoes there mate. Fascinating to ponder how those rocks were formed
Frostgiants
I have to say Dave, you Australians have the nicest boulders, That first shot was a little more spectacular than usual. Thank you for making your hard work to look like fun, I am just joking, you are one of hardest working men I ever seen. ... :-)
Appreciate that. Thanks for watching Kevin.
Boy all that free granite stone. I would have used it to make a stone foundation. Especially with granite stone. very very cool video.
Thanks Cory and thanks for watching.
Another hole blew out the bottom?
OH no, Dave’s stick fell over.
The first blast was all good, the second blast had one hole in the rock up near the front fence go through when I was drilling, that was OK because I stemmed it up prior to loading and that worked OK. The other rock was OK when drilled but broke through the bottom when fired and left a big chunk of unbroken rock and what looked like it could have been a missfire. I carefully removed the stemming to investigate and found the blast had broke through and made a huge cavity underneath. A new and shorter hole was drilled and fired to break this bit up.
You need to make a seat for that drill lol, that way you just sit and drill away 😂
Cool stuff..
Thanks for watching DC
having this in the back ground, almost sounds like you're gulfing at a gun range lol
Thanks foe watching RF
You sir, have a cool job!!
Thank you and thanks for watching.
That's gotta be such a satisfying job!
It is James.
Couple of nice shots mate
Thanks Skeets.
And that is the day you remember you actually wanted a house without a basement! lol
Hello Dave, Happy customers are the best! Great job - as always! Just curious - on the whale rock - how long did it take to drill one deep hole in real time? That Granite can be nasty hard! Take Care, Stay safe! Jim
A 6 Foot 1 1/2 inch hole takes about 10 min?? (1.8m x 38mm)
Got to say, the amount of construction happening in this geographical area is HUGE &! the amount of rock I see sifted through the buckets of the machinery & loaded into piles 8 - 10 ft high all around the edges of the landscape is absolutely immense.
One site I've been watching, it's been 8mnths & they STILL haven't finished.
If YOU haven't been part of it, I'd be mighty surprised.
All of the rock around Mernda is just basalt and most of the time they just bash it out with huge excavators because many construction companies are fearful of blasting and would only undertake it as a last resort. Thanks for watching.
@@demolitiondavedrillandblast You know your profession a LOT better than I do.😳
To me it's all rock🤣
@@demolitiondavedrillandblast So, I assume the quarry at Wollert is all basalt? & that's what they're using for concrete mixing?
Yes.
Turkey and Syria that were hit by a huge earthquake, reporters said it was like the cities were bombed from underground. After seeing this even small explosion I understand why so much more now.
another great video Dave, toward the end i wondered if your going into the aggregate business lol.
were the last two a bit shallower or maybe softer?
Second blast not loaded as hard Amanda.
Dave if this was an Olympic event, you'd bring back a gold every time!
Hahaha, for sure.
And then he would blow it up... Lol
i would love to watch them dig it out the rest of the way . great video by the way
Yeah, I can watch it all day Noah.
The rounded weathered look of the rocks suggest that there was either a river or beach there once.
Yes, certainly. Interestingly though I often find these rocks with rounded edges tightly locked together like they are carefully fitted.
Looks more like glacial travel. It's the only thing that can pack the rocks like that. I wonder if it was a glacier
I'd kind of feel dumb, for not incorporating those boulders into my home/landscaping. Hell, set the house on top of them all.
And have to climb over the whale in the hall way???
Wow that seems like a crazy amount of work to have to reburry and redig them for the explosion
What is the option?
This looks like a fun job.
It was!
Anyone who knows anything about rock, knows that hot rock doesn't cool down to cold rock. heat rock up and it separates. metals, glass and slag. living things that cannot rot, crystallise out, metals and silicates stay in situ. so you could be right when you say "whale".
it would be interesting to get those things out of the ground whole.
I’m glad the only drilling and blasting I’ve done was with a cab drill and a tamrock and not a woodpecker!
yes... my axera7 was allot easier than offsiding a rise miner...we couldn't use the leg cause we were sinking a rise ...guess whos job it was lean on it with a 3 foot steel
Every good driller has started out on a sinker or an air leg.
@@demolitiondavedrillandblast oh I’ve used them. Slab jacking concrete crew screw ups when it’s not worth breaking it up to re pour it. I tend to agree though. With a big drill you’re never going to learn intuition about what gets production out of the machine for the type of rock you’re in. When you are holding the toll you can feel what’s going on and learn.
@@demolitiondavedrillandblast excellent work though. Got it all down to size for the equipment available to muck it out, didn’t send any fly rock anywhere, much less anywhere near any of those houses!
Next you will be adding a chair on your drill. Ride it down.
That first shot puffed a little but it did the job. So the contractor is happy
Everybody is happy.
Great video thanks Dave. Excuse my asking but how deep do you decide to drill your blast holes?
Generally I would drill just a little deeper than I need to break Gordon.
Thanks Dave. I did wonder
some heavy rock blasting right there
Oh yeah, thanks for watching.
Have you ever done a video on how you got into blasting or some of the common explosives and setups you use?
Not yet.
@@demolitiondavedrillandblast That type of video would be most interesting.
@@demolitiondavedrillandblast when are ya gonna make a compilation of the best bangs? & Maybe any blunders?
Anyone else notice the rainbow? When he is covering the rocks up
Another amazing video of Dave blasting rock, having a blast as well and getting paid (really well) to do his thing. Thanks mate
Glad you enjoyed it
Expanding gum would have done it easier
That looks like an interesting structure. How did it get there?
Glaciers probably, troll activity is a much less likely explanation!
Boom goes the dynamite. Nice job.
Thanks for tuning in Sonny
wow awesome videos
Glad you like them AA! Lots more to chose from.
You made quick work at that!
Yes, Two big days work.
What an awesome video, thank you. What brand of boring bits do you use?
The knock on button bits are mostly LHS Rock tools, made in China, good quality.t The drill rods are Atlas Copco / Secoroc / Epiroc. they are so much better than the rest, that is is worth paying the high price
@@demolitiondavedrillandblast thank you for the information, I love the channel
The hydraulic spoon has another busy day.
Solche schönen Steine macht man nicht kaputt
Sie können gerne kommen und sie mitnehmen
How many people caught the rainbow in the background when the excavator started filling in around the rocks
The harder the rock, the more unforgiving it is when you load it a bit more, hence the gravel in the bottom. 😃
If we can use the blasted material on site, we do it on purpose to have smaller fractions, or we run the material trough crusher bucket on the excavator. The only measure is a happy costumer 👍😉
It would be really great to have a small crushing and screening machine. Thanks for watching.
goodiezgrigis, can you direct us to a video of one of these crusher bucket things you mention.
@@vsvnrg3263 just search "crusher bucket" on CZcams, there are alot of videos. We use MB crusher 90.3 on a 18t machine and it works.
@@goodiezgrigis , crusher bucket? will do. thanks.
@@goodiezgrigis , ive just spent a couple of hours checking these things out and i now need a cold shower. not for every job but boy oh boy what advances in technology. some of them dont seem very well thought out. if i can see behind the crusher mechanism you can count on stuff snagging in there. when i started in an excavator, rake/sorter buckets were just entering the scene.
Love the video new to the channel do you ever use RDX cone shapped charges for stuff like this?
Welcome Aubrey, don't generally use those for breaking rocks, expensive, inefficient and extremely loud. Only place that I have used similar approach on rocks in dislodging rocks that might slip down onto a road way from way up a hill - far to difficult to get a drill up there.
@@demolitiondavedrillandblast I appreciate the response! Happy blasting
It appears to be an igneous rock but I doubt it is dolerite. Dolerite tends to have iron in it which turns the soil around it red when it decomposes. The rounding can be caused by glaciation, river erosion or decomposition due to acidity in the surrounding soil. But in this case there did not appear to be decomposition.
Hi John, the Geo's tell me that it is Granodorite type I en.wikipedia.org/wiki/Granodiorite
Everything seems to be more fun when you get to blow shit up. 🤣
Why didn't they just lift them out?
Drill holes, add anchors, lift out with small crane, sell granite stones to be made into counter tops or large landscaping rocks.
If it were that easy they would have.
Looks chilly there! We were 110F with the heat index today. Humidity has been horrible here lately! Do they do anything special with the busted rock or is healed off to a dump site??
All of this rock went to a guy that specializes in supplying landscapers etc.
Hard Work, Smart Work Team Work... DDDB style, good on ya Lads
Thanks Mac.
Pretty cool! On the whale rock did you set timed/sequential charges to take off the perimeter first? Seems like the smaller 9-charge rock was all at once.
All of the holes were timed with 17m/s between the holes.
@@demolitiondavedrillandblast What effect does the 17ms delay between holes have? Why not set them off all at the same time?
Imagine that being an ancient monolithic artifact that was just destroyed.
Your imagination is very good.
Nice!!!!!!
Oh yeah!
Wow, that first blast was (almost scary) violent sending big pieces of granite out of that mountain of dirt. Was that what you expected to happen or was it a matter of too much explosives (nah, I don't think so) of not enough dirt? Speaking of the amount of explosives; how do you know how much you need?
Hi Rob, I expected that it might throw a little bit - we moved our vehicles for this one, a case of would have liked a bit more dirt but were running out. A small amount of soil came out of the hole but nothing left the site. Knowing how much bang is required comes down to the ratio of Grams of explosive per cubic meter of rock that needs to be broken and a fair bit of experience.
Dude is never going to have circulation problems in his legs.
Can you leave the blast wires and bits in there or do you have to sift it all out?
I usually grab out what I can.
Good tunes
Thanks Wes, they are all CZcams royalty free music from the music library, these track all by Silent Partner.
Bangerz and Smash!!!!
Dexpan expansive cement will break them up. Works great
A lot more drilling and waiting (I use heaps of that stuff).
What ms delays are you using? Also what is the time difference from the white to yellow?
The whites are 42mS and the Yellow is 17mS
That looks like such an expensive job.
Not in the whole scheme of things.
Could see the start of a rainbow curving down onto the old pot-o'gold ie your work that front rolling through for the 1st blow. Did you find any?
Ahab Dave puts the hurt on Moby Dick Granite, and some of it`s little friends. I will agree with David Handley`s comment, Dave does work hard for his money, but Aussies are a tough breed, and are no strangers to hard work. Thanks for another great video, Dave, and be safe. Cheers.
Thanks for watching ##62, Yes, I'm feeling a little bit weary having drilled more than 200 holes in the last few days since this job.
@@demolitiondavedrillandblast Hey, you take care of yourself, and don`t over do it. That is an order from your subscribers.
Big Dave, I’ve seen some blasters shoot rock and covering the blast with a big rubber mat, like strips of old tires (or something). Seems easier and faster, but not sure of your rules in Australia.
I was wondering that myself, but then I thought, Dave would need a bigger vehicle to move them around, and they don't really help Dave they help whoever is paying the excavator to move the dirt around.
Yes, I have a heap of these Michael, I need to bring them to the job on a truck which costs money, the soil is already there. The soil also gives a higher level of protection and cuts the noise down drastically where the mats do little for the noise. The blast noise brings complaints and spectators that I don't need.
