That job was a tough one Dave. You played just about every card in your hand apart from your own drill rig. Explosives, Expando goo, the crowbar and the plugs and feathers, all got a good workout on this job site.
Yeah, I nearly took the little drill but it would have been a bit hard to get past the first bunch of rocks as it is not very maneuverable when it has the drill mast fitted instead of an excavator bucket.
Nice job,👍👌. Wish I had you around this summer. No blaster around here wanted to deal with my rocky hilside behind the house and workshop. 3.5m wide and 45m long track. No explosives, as both buildings are on the same hilside rock and i had to remove uphill. Lets just say that 80 kilos of expanding agent and countless holes removed around 75 cubic meters of nice chunky rock and it was satisfying to do it myself.
Dave your diligence once again paid off your work was especially crazy hard, but my friend when you got up and straddled that rock while using a jack hammer I knew that should be you advertisement photo " saying I will crush yours so don't try and bust mine!!!!
Thanks brother, that was a cool video. Nice accomplishment 👏 👌 I especially liked the steel wedges used. I've done some of this by hand and machine, and its definitely hard work. So... Again, thanks and peace ✌
Something very soothing about watching stuff being blown up! Not so soothing for Dave, though, who has to do all the preparatory hard yakka. I wonder that your bod hasn't been vibrated to smithereens by the rock drill!
just a suggestion Dave, how about 2 holes on the side of that tall rock and insert 2 drill bits then put a plank on top to stand on? Thanks for the Vid. John
Just to follow up; I watched this video on my kindle on the last day before "lockdown" here in the UK, in a pub :D Nicely done Sir, nicely done. Cheers.
Hope you enjoyed it Mr. Lamb. Lockdown sucks, but it (along with masks and other measures) turned the situation here around, 7 days in a row now with no new cases!
I try hard MrB... but still some people complain and say there should be no music, I ask them "well, what would you put with a time lapse scene where the is no sound"? - No answer
Every time the quarry near my house blasts the slab floor thumps , the dog is startled and sometimes it even catches me off guard. Thankfully it’s usually mid morning but they are too far away to hear the warning siren. It’s only once or twice a week and the quarry was there before they built the neighborhood. The whole metro Atlanta area sits on the granite that outcrops at Stone Mountain.

A Dave demolition derby - some crazy size bad tempered rocks. Must have killed a few drill bits - some pretty deep holes too.! As usual I think of your poor old back. Cracking goo is great - super results - cost effective hopefully. Lockdown must have been hellish. That tall block looked like a massive tooth in profile - and a climb to drill it.! More satisfying slo-mo. That final plugs'n'feathers was a real devil. Great work Dave - more to add to your already extensive video diary.
Thanks for tuning in again Chris, The lockdown was pretty annoying for me, for some people it was just too much sadly... but id did work well along with masks etc, no new cases in Melbourne now for 7 days!
That's some hard rock , Great video . Gotta question , is the rock crushed and recycled ? I thought our granite here in Arkansas in the USA was hard but I believe what your working with is harder . Keep the great video's coming .
Dave, 2 years later did Wayne get his driveway completed? Some of your old videos popped up in my feed recently and have been binge watching some of your videos from 4-5 years ago.

Disrupted the world for not a lot of benefit.
That was certainly some tough nuts to crack. All that rock would been good candidate for taking to crusher and bring back repurposing it on the driveway. That stone was hard as any driveway stone you could purchase.
My kids 'When we go over and see Josh, u gotta see Dave too. His jobs the best.' Im greatly disappointed they not thinking dad is cool coz hes a concreter.... ☹
@@demolitiondavedrillandblast that just put a thought in my head... when looking for land to build your house make sure its not next to a quarry... thats a factor i never considered before
The sequential reuse of the cover, and using the rock as the cover base was poetry in destructive dirt! How much does the expanding goo cost compared to expanding high explosives for a comparable size rock? Like other than having to wait, and it not getting the fragmentation and movement that explosives get, what are the downsides? Oh, I suppose that you would need to drill more holes, thus higher labor costs... And it's not NEARLY as satisfying lol
Your dust control is fantastic .. is it some sort of cyclone? How does it all work? I have trou ble with concrete dust . !! A workshop vacume can't handle it it's to fine and light just blocks the filter .
Hi Mark, you need a "H" rated vac, one that has HEAPA filters on the outlet and reverse pulse cleaning for the main filter, prior to the vac you want a cyclone separator that will catch all but the smallest stuff, Have a close look at this one, I have two and can't recommend them enough - www.husqvarnacp.com/au/machines/dust-collectors/s-26/967663902/

Having watched a good number of these videos now I can see a common theme running through all of them. The groundsworks contractors all seem to put the smallest excavator on site that they think they can get away with. I'm sure that if they went up to the biggest machine that could operate on site the breaking out of the broken rock and clearance would be a lot easier and faster.
Often the case Bill, what really gets me angry is when I go to look at a job that has stalled due to the rock and there is a big machine sitting there... but when I come back to do the job they have taken it and brought back a smaller one.
@@demolitiondavedrillandblast Many thanks for the feedback. Just wondering where all these big boulders have come from in the first place? Is the base geology granite as well?
Watching you sit on that rock I see why you don’t wear skirts like those three barefoot blokes in the hole. That backwards method was impressive, I think I want to be like you when I grow up!
When you have a difficult position with a rock drill you have to use your imagination. You are referring to the Indian guys sinking a shaft, drilling barefoot?
Have you ever considered having a weighted saddlebag type setup for those tougher holes that you can’t get your own body weigh over Dave? ie load the drill with a weighted sleeve or bar weights setup perhaps ? Just a thought 🤷🏻♂️
I'm really considering buying a drill tower for my mini excavator and testing out that expanding cement here. It looks so hard drilling by hand. Looks like the cement and a hydraulic breaker would work good on the bedrock we have here.
Great idea! You really need both as there are some holes that you just will not be able to reach with a machine mounted drill. The low ground temperature would be a problem in the colder months I think.
@@demolitiondavedrillandblast I'm hoping to reach everything with the drill tower and a rototilt 😅 I found a cement that is rated for minus degrees actually, never tested it but internet days it works 😀 it got a range from - 10 to 0 Celsius and also 0 to 10 Celsius and so on, so hopefully that will work up here 😊
I'm an Aucklander & i work in the city right next the massive cut 'n cover rail tunnel opening being built. Every day all we hear is the never ending constant racket of the multiple rock breaker excavators doing their tappy tap tap tapping away all frick'n day long.... The problem is the sound permeates up through the multi-story building we're in on account its probably sitting on the same base rock 'slab''.. i wish they'd just drill the stuff & blast it out in layers (whatever) to the huge depth they need to go & be done with it.... We've already had 6 months of the tappy tap just knocking down the buildings that were there. You'd think they go for the most high tech high cost method on account there's a bottom less source of funding to pay for it all, but what would i know. i'm no civil engineer.
I often wonder if somebody even bothered to do the sums for these projects to see if blasting was viable, you can bet they would have blasted it 50 years ago Peter.
Tell Wayne to pick a different site for next house... one with less bedrock..Have to wonder who put sewer line in, when, and how. Did they have to blast a trench?
@@demolitiondavedrillandblast NOT TO SOUND CLICHE......BUT IT'S MY PLEASURE!" THANX FOR THE CONTENT! COULD YOU PLEASE DO A VIDEO OR INCLUDE WHERE THE DEMO'D ROCKS GO?
My back hurts just watching you. That is some strange rock that was black and shiny inside and it looked like there were several different types of rock on that site.
Love the blasting but with it being covered in the soil for safety purposes it loses some of its excitement. Watching you split a rock with those wedges is very satisfying. Also, the big nose picker at the end of the excavator is fun to watch. Watch the goo and poo!!
I’m very new to this channel 1) why didn’t you use blast mats on this job and 2) where do you get rid of the broken rocks , thanks Dave , excellent entertainment .
Welcome Ken, Once upon a time we used blast mats on every job, I prefer to cover with soil now because I don't have to truck a few tonne of blast mats to the site and spend my weekends fixing them, dirt kills the noise really well and hence no complaints, mat lets most of the noise through. This guy used the rock on site.
Well, that was fun. Is clearing the broken rocks off the site part of your job? Or you just get the site down to a particular height? I have done a lots of earthwork but never had a chance to work as your offsider does....and that's a shame.
Deary Demo Davey: What do you do with the dust your vacuum takes up? Can it be re-used for grouting? OH! And why do you drive on the wrong side of the road? Yours Truly Your Yank in Kale-ifornia.

Hi Luke, a misfire like this is a rare event and we have methods in place to detect this, first indicator is the witness tube that sticks out from under the cover from the last hole in the sequence, this lets me know that the blast has propagated all of the way to the end.
@@demolitiondavedrillandblast Thanks Dave I would love to see a more technical video where you go into the details of the explosives and equipment you use, how it is set up and all those details
Will we ever get "Dave's Storytime - Tales of the days it all went wrong"? or at least when a bit went wrong and was funny as f... you know what I mean :D
Question: with the cracking goo why does it not expand out up thru the the top holes ? If it meets resistance when it expands how come it expands side ways? Amazing stuff !
great work again Dave, iv seen that you use different length drills for thicker rocks , so on each drill bit do you use different drill heads on each one ?
Hi Paul, on this job the blast holes were all 35mm and the holes for the cracking agent were 38mm, when I drilled the deep 1.8m holes I used three rods, 600, 1200, 1800mm, They all had 38mm knock on drill heads.. however, as these drill heads wear the not only get face wear on the buttons but also gauge wear (diameter decreases), so a lot of care has to be taken when selecting a series of drills so the the short one does not have more gauge wear that a longer one or the longer one will not follow as the hole is just a tiny bit too small.
That job was a tough one Dave. You played just about every card in your hand apart from your own drill rig. Explosives, Expando goo, the crowbar and the plugs and feathers, all got a good workout on this job site.
Yeah, I nearly took the little drill but it would have been a bit hard to get past the first bunch of rocks as it is not very maneuverable when it has the drill mast fitted instead of an excavator bucket.

Welcome Ken, Once upon a time we used blast mats on every job, I prefer to cover with soil now because I don't have to truck a few tonne of blast mats to the site and spend my weekends fixing them, dirt kills the noise really well and hence no complaints, mat lets most of the noise through. This guy used the rock on site.
@@demolitiondavedrillandblast , thank you for taking the time to reply Dave .
Well, that was fun. Is clearing the broken rocks off the site part of your job? Or you just get the site down to a particular height? I have done a lots of earthwork but never had a chance to work as your offsider does....and that's a shame.
I just have to get the rocks down to level. Rick gets rid of the rocks.
I saw the title, and am confused... I thought the only first name in Australia was "Bruce"!??!?!
Yeah, we called everyone Bruce to avoid confusion!
I notice that you don’t use rubber mats. Wouldn’t it be faster for the small shots?
Yes but the blast noise attracts a lot of attention and complaints, with soil cover the noise is very mild.
I'm surprised you don't have a pick or spade for your air drill, to loosen or 'persuade' fractured rocks to move.
I have a large and heavy jack hammer, try not to use it too much though Richard.
@@demolitiondavedrillandblast Well, you make the cracks, it's someone else's job to exploit them...
I was waiting for the poo-pipe to get blown to shit. But Dave has the mad-max skills not to do that.
So what did you think of the test drill your supplier sent out with you? Glad to see you using a jack leg, better for your back. Nicely done mate.
The Puma drill was a shocker to use, short stroke high frequency drill was a very high operator fatigue unit.
@@demolitiondavedrillandblast That would either shorten your day and production or shorten your life. LOL
Deary Demo Davey: What do you do with the dust your vacuum takes up? Can it be re-used for grouting? OH! And why do you drive on the wrong side of the road? Yours Truly Your Yank in Kale-ifornia.
First time I went to Canada I was told it was all metric and wrong side driving. They had their laughs. :)
The stone dust usually gets buried or taken away with fill.
Infront the hardest rocks, we always need the hardest explosives, the expansive cement won't service ...
i am a Rock i am an Island demo dave lite my Fuse 💥🧨
that Big rock in middle 1 tuff hard yakka mate you can hear it tear like glass .
chit when Straya was made they didnt fook about . tuff rocks there 👍
Anyone else , slow Vidga down📼 1/2 speed & watch the house Oposite Guy in blue jacket solar panel house & cat in window starts about 29:20 :) i wonder off watching backgrounds .
i wud hate the bill for this road up to the House $ ?
I'll have to have a look for the guy in the blue jacket.
@@demolitiondavedrillandblast thats the 1st reply ive gotten in here
yeah i played it at 0.5 speed after the 1st run starts about 29:20 when camera is pointed at house across the road Enjoy if time
Nice! Though I reckon it's just about time you ground that hammer and those plugs a bit so you don't risk iron splinters.
Got a new hammer yesterday David.
Great video. What was the total cost of the driveway?
Not cheap, but not as much as it should have been.
That was an awful lot of hard work. How do you check all the charges have gone off and there is nothing left on site unexploded
Hi Luke, a misfire like this is a rare event and we have methods in place to detect this, first indicator is the witness tube that sticks out from under the cover from the last hole in the sequence, this lets me know that the blast has propagated all of the way to the end.
@@demolitiondavedrillandblast Thanks Dave I would love to see a more technical video where you go into the details of the explosives and equipment you use, how it is set up and all those details
Maybe you could do a technical playlist of all the technics you use
Will we ever get "Dave's Storytime - Tales of the days it all went wrong"? or at least when a bit went wrong and was funny as f... you know what I mean :D
Probably not Andrew as when things are not going to plan I really don't have any time to make video.
@@demolitiondavedrillandblast I was thinking more that it would be stories of when it went wrong in the past rather than vids of 'as it goes wrong'.
Question: with the cracking goo why does it not expand out up thru the the top holes ? If it meets resistance when it expands how come it expands side ways? Amazing stuff !
it goes hard in the hole before it starts working.
@@demolitiondavedrillandblast interesting
great work again Dave, iv seen that you use different length drills for thicker rocks , so on each drill bit do you use different drill heads on each one ?
Hi Paul, on this job the blast holes were all 35mm and the holes for the cracking agent were 38mm, when I drilled the deep 1.8m holes I used three rods, 600, 1200, 1800mm, They all had 38mm knock on drill heads.. however, as these drill heads wear the not only get face wear on the buttons but also gauge wear (diameter decreases), so a lot of care has to be taken when selecting a series of drills so the the short one does not have more gauge wear that a longer one or the longer one will not follow as the hole is just a tiny bit too small.
@@demolitiondavedrillandblast thankyou ,im learning something .
Did ya bore track and profile the face holes?
Hahahahh yeah, of course! The calibrated broom handle is my bore tracker. Thanks for watching Glen, please like and subscribe.
