Breaking more hard Granite without explosives
HTML-код
- Опубликовано: 15 сен 2023
- As part of a larger housing estate development project I had to bust out a large piece of hard Granite rock to make way for underground services. This is not difficult when you can blast it but on this occasion we were working near a live fiber optic cable and probably blasting was not a really good idea... Expando chemical cracking agent to the rescue again - drill, mix, pour, break.

👌👍
The RUclips gods have started recommending your videos to me again.
Yeah.... see how long that lasts.
Nah, don't worry about buying a gimbal. The vids are great.
Thank you Dave. They should have called you first. The job would be done already.😅Man I like that red drill.😅😅
I could hear them hammering weeks ago when I was on another job near by. The Red drill is a rocket, for sure!
Telstra/NBN cable/conduit, etc. is rare to be covered or surrounded by anything, some of the stuff even runs through the tree tops, tree roots, and on top of rocky ground fully exposed. Although it's quite tough it doesn't like to be bent at sharp angles.
Yeah... such a high value asset often gets just buried unprotected in the ground, I have seen that as you say, crazy
The cable itself isn't the great value. It is all of the user's downtime. They put a machine on each end to send signals, then plug on splices. The one we cut was up in a day. The locator didn't mark it.
Some of those locators are rookies and others are just to lazy to be careful and mark out with accuracy, over half don't even know the correct colours that should be marked to identify the assets.@@Michael-rg7mx
Good morning Dave what a way to start a Saturday morning. Great video Dave.
Morning Bob, enjoy!
Can’t wait for next episode, best show on YT! Cheers!
Plenty more footage that needs time to paste together.
Loving the trippy soundtracks in addition to the rock destruction @Dave!
Thanks, This one is from the RUclips royalty free library, It called Ladybug.
Hello Dave, another masterpiece. I always like seeing another guy my age run a sinker drill well. We now have new requirements for blasting near gas lines. Any blasting within 500 feet of any gas line requires a pre, and post blast survey by the gas company, plus independent monitoring from a gas company required third party vendor. Something smells fishy. Usually takes a month to get it all together.
500 Feet!!!! oh... for goodness sake. Saddest part of the whole thing is that you end up forking out good money so other clowns can waste your time. Yeah... I had a bit of practice on these drills, I'm on air compressor #6 and this one has a lot of hours on it now.
Nice shot ! That’ll get you home enjoying a frosty Fosters everytime! 👍🔥💯
We don't drink Fosters - that is for export only
Hiya Dave, monty mcwillam here. I've moved to another channel. Excellent operation.
That Expando really worked well on that!
Thanks for sharing 🇨🇦
It does when you drill the holes close enough, deep enough and the right diameter. Thanks for watching Paul.
Your going strong Dave thanks for sharing 🦘
I try Kerry, thanks for watching and contributing.
Hay Dave nice job again ❤😂from madmax Melbourne 👍👍👍👍🇦🇺🤪🤪😎👏ps I have seen you on the roads
Oh... I'm getting noticed... where in Melbourne are you from Max??
@@demolitiondavedrillandblast hay I am in Greensborough from madmax
i’m impressed at how well controlled your demolitions are.
it’s like you wouldn’t crack an egg on top of the demolition site during the deterioration.
Thanks Paul, you obviously have not watched this one - ruclips.net/video/Z9N-kRYlOz8/видео.htmlsi=Gc8UX3KLjmEZiZ02
@@demolitiondavedrillandblast I would honestly counter, that while the example given would have cracked an egg...I second Paul's sentiment...it was perfectly controlled. Nobody got hurt...well OK, one Magpie got a concussion, but he was able to fly away so no harm done. Rock needed to go = Rock Gone. 🙂
Dave in the many years I have been watching your videos it’s the first time you have no mask on when using that gunk of cracking agent. I had the pleasure last year of helping my mate using that stuff and took my mask off and it made me cough like hell.
It is pretty safe to pour without a mask as long as you have eye protection to protect against any splashing but never mix it without a good mask - you know why now.
Another great video Dave . 🎉
Glad you enjoyed it William.
It's always good to come back from a weekend in the woods to see a DD vid. Saw plenty of your countrymen out on the Pacific Crest Trail over the weekend. I had my fair share of rocks to pop out of the tread, but none as big as what you deal with. Great stuff as always.
Glad you enjoyed it TC. Lots more video from this job coming sometime...
@1540 - "Let's GO!" More like Let's GOO!
I'll use that.
Cracking video as ever Dave.
Thanks.
First of all, I just want to say that I really appreciate your channel, every one of your videos has been a pleasant, relaxing watch with an excellent sprinkle of humor and technical information which is just what my brain loves 😊
Cracking goo is fascinating to me and I'm curious how/why it expands outwards forcefully enough to crack the rock rather than just expanding upwards to ooze out of the open hole? It seems like expanding up would be the path of least resistance, so how does it exert any force at all on the sides of the hole?
Good question, it first hardens and then continues to expand.
@@demolitiondavedrillandblast Just like my ex wife.
G O L D @@-unclebuck-
When the blast went off, all I could think of was the movie Tremors. Lol!
G'day great video mate. You had one hell of a job there
Glad you enjoyed it Murphy, thanks for tuning in again.
172👍's up demolition Dave the most explosive man on RUclips thank you for sharing 😎
Sure did and it was strait
did you get the drill bit back or a steel banana??
yeah, enquiring minds need to know. Or did it leave for orbit and not come back?
It was good Rodney.
@17:48 - I'm surprised they didn't wait. When you have a contractor on site for a specific project, you really shouldn't jump ahead of them on their own project. Just my opinion.
Happens all of the time.
G'day great video mate. You had one hell of a job there. Another great video Dave . .
Glad you enjoyed it Brittany, I have lots of editing work to do, so more coming soon.
Maybe these Telstra guys are the same ones that give the sewer and drain jetters work when they punch thru drain and sewer pipes?!
No more reaming pipes here for obstructions without video tracing them first. The gas guys are pretty good a piercing those sewer lines. Vac trucks do all the pole holes these days as well.
hissss!!!!!!!!!!!!!!!!!!!!!!!!! you said that most hated day.
Mondays are evil.
~poke~ what did the drill bit look like when you got it out of the hole?
You have been quiet recently, got it out all good.
@@demolitiondavedrillandblast fighting my comp, it keeps on breaking down on me.
Just **ROCKED** up to site on monday - Get it ???😂😂😂
Good combination of "smoking" and "non-smoking" lol
Never thought of it like that Tim.
Another satisfying episode 😁😁😁😁
Thanks for watching.
What a great controlled explosion. You must know what you are doing.
If I had a huge granite block you’d be the one I call.
I’m surprised no one is required to yell “Fire in the hole” 🤠
Must be only in America.
I seem to remember an American, road crew blowing up a whale on the beach.
The video of the whale (circa 1070) has been restored and can be seen on RUclips.
when you use the expanding material is there ever an energetic release such as loud cracking noise or rocks popping out? How long does it typically take the expansion to happen? minutes, hours, days?
I would generally leave it for Two days in Granite, weaker rocks like Basalt can break in just a few hours. You can hear it creaking and groaning.
I gotta wonder if you've ever found mineral veins or crystal deposits while doing this. Seems like a great chance for rare rock collecting too.
I hope your drill rod came out in good shape. Good luck with the springtime jobs. Summer was a bugger in the northern half.
It came out all good for a change, I was expecting it to be ruined as the rod and bit were both brand new.
Weather forecast here for today is 26c - 8 degrees above average for this time of year, kind of good after last year as the spring was wettest since 1930~
Wow, and both were new. That is indeed a strange stroke of luck.
Great job Dave! It always amazes me the power of the cracking agent.... the presplit holes looked vertical and it still managed to crack the rock. Is the red drill the CP? In any case, thanks for the video
Glad you enjoyed it, Yeah the goo worked well on this one and the Red drill is the CP69.
Great video Dave. Glad to hear you are looking into a gimbal, the handheld shots are a little jerky. Try messing with the settings, a lower frame rate might help smooth out the handheld shots.
I will check it out, the regular rate I have been using is 60, other options are 24 which I don't really want to use and 120 which I use for blasts as it makes a nice slow-mo when expressed as 30fps. gimble is the ultimate answer but I dread carting more stuff around with me, I don't have enough room as it is.
@9:56 looked like explosives to me. And i liked it.
Yeah that was.
Dave, some great split content! Do they not use colored conduit for the different applications in the ground works? Fiber would be in a Orange conduit here in the states. Everything I see over there is white.
Over here electricity is Orange, Comms. cables are white, Gas is Yellow or Black with a Yellow stripe, water Black with Blue stripe, recycled water Black with Purple stripe.
Hey Dave, Nice work! Love seeing you at it!! What's your deepest hole you are drilling?
These holes for the chemical cracking agent were 1.8m (6 Feet). Some of the blast holes were a bit over 2m.
Dave thx for the video. Did they start to early in your expando trench with the excavator?
They sure did.
It would be cool to get the reactions from the crew working the machines on how much easier you make their jobs. Every equipment operator I have ever talk to really hats busting rock. It takes forever and the machines vibrations do a number on the operators.
The guys I'm currently working with are quite pleased - it will be in the video after next.
Dave , what do you look for in a excavator driver ? You have worked with many to rid the world of rocks in the way .
Great question Philip, I look for a guy that is willing to get out of his machine and have a close look at what he is trying to dig. So many of them just can't manage that.
I should be over end of the year. Might see ya
You said that last year.
Home owers wife.. OMG get that dirty bit of Granite out of there.
Also Home Owners wife ... OMG So got to have that granite counter top and tiles.
Nice video.👍👍👏🏻👏🏻
Thank you 👍
Unpopular opinion: having worked with fiber optics for decades, unless your shot went really wrong, it probably would have been fine. Even if it wasn't, the whole span being exposed, it would have been cheaper to fix it than the measures taken to protect it.
I hear you Dave, in my opinion it was blastable but they would not have it. I did work on another job near by where the contactor moved the fiber himself because he could not wait weeks for Telstra and they came down on him very hard.
@@demolitiondavedrillandblast For sure, I am aware of anxieties beyond our power and doing things the way the powers that be dictate and pay for...
That rock may have been hard but it was also brittle.
Yes.
MM77 Approved 👍🏼👍🏼
I always see those drills blowing out mad water in mines not from the drill water lubrication but the air exit? Is that dirty air supplied and if so doesn't that roach those drills?
They blow a lot of water or condensation out the air exhaust when the compressor is sucking in humid air Scott and there is also a lot of oil mixed in with the air to lubricate the drill, it's not good air to breathe.
@@demolitiondavedrillandblast yea I would guess not, just in the shop as a car mechanic, if the compressor has a lot of water in the air feed it destroys your pneumatic tools pretty quick, but if they add oil to it, I would guess that would actually help?
Reminds me of the Amazon trucking center job i had. They swore the concrete was only 10 inches thick. It was 18, and had 1"x20" dowel pins that couldn't be wet set.
NBN Co contractors are the laziest bastards you'll ever see, it's nothing to see completely exposed conduits nevermind conduits buried way too shallow because they couldn't be arsed removing underground obstructions preventing the cable from being buried at correct depth. At least we know you do your job properly Dave and have video evidence of it, keep up the good work mate.
Shocks me how shoddy the installs are 351, plenty of fiber just buried in the ground without conduit!!
As a long time telephone repairman I find this abhorrent, but you get what you pay for I reckon.
@@russellsmith3825, and everyone wants their nbn now. when they first put phone lines in in my area they did quickies. insufficient depth, no conduit. and they sunk it on my land, not on the verge. i found it when digging foundations for a fence. telstra told me it was no longer being used but was installed in haste just to get phone services to as many people as possible. the proper lines were installed later correctly.
Wish the would remove the "no longer used" services so that people don't have the stress of digging it up.
@@demolitiondavedrillandblast my company doesn't mark abandoned services and cables, if the person doing the locating has been around long enough, they might advise you of any abandoned facilities in the area, however if a cable is retired it is removed from our prints.
When I watch these types of videos I wonder why waterjet rock blasting/cutting isn't more widely used.
Hi Dave, I was wondering why you always use the dust extractor, even when there are big excavators creating even more dust than you are producing? Also wondered if a face mask with a powered filter might be more comfortable than the old gas mask?
Guessing that it's because silicosis is a cumulative exposure problem. But that's a risk factor - some people are unlucky and develop problems at low exposure, others can, as with a similar issue "smoke all their lives and live to 100".
Dave seemingly doesn't want to rely on getting lucky. (guessing thatt's the old bold thing... there's old explosives users, and bold explosives users, but there's no old bold explosives users)
That old gas mask is the finest unit on the market, It has a organic vapors canister and a P3 particle filter canister. When you see the WHO dealing with Ebola cases, this is the mask they will be using every time. This unit exceeds the P3/N99 rating. It is actually very comfortable - I recon I could sleep in it.
@@demolitiondavedrillandblast Kinky...🤣🤣
Another interesting video Dave - didn't realise the temperature was quite so critical regarding the use of Expando.
What keeps the goo from just extruding out the top of the bore? Seems that would be a path of least resistance.
It hardens first and then expands, as @-unclebuck- said - just like his ex wife.
Howdy demo Dave
Howdy buddy.
Did you get your drill bit out in one piece, missed it somehow? Thank you and have a great week.
Yes I did.. and it was strait.
@@demolitiondavedrillandblast Thank you.
No boom, but still satisfying.
Keep watching....
Yep. There was a boom as well. 😬👍. I was just referring to the goo break. The goo was impressive though. I loved the sawcuts. Wishful thinking.
Yeah the saw was a ripper, excavator mounted with a 1.8m blade, max depth of cut was 700mm, very slow though.
What keeps the expansion liquid in the hole? Why don’t it just ooze out of the top.
It first hardens and then expands.
Legend.
Thanks
Thats tough work
Sure is Phil, at least the big drill rig is on the job now.
Hey Dave, how do you go about estimating and charging for a job like this? Do you go by the tonne, cubic metre or hours and materials?
All time + materials.
@@demolitiondavedrillandblast thank you, I appreciate the fast response! 😁
Do you have a video demonstrating how the epando works? Like pouring in a PVC tube or maybe a coffee mug or old piece of pottery?
No, I have Two time lapse videos of it in rock though, here is one - ruclips.net/video/04y4k8bJMns/видео.htmlsi=OTk9KHQo6plnTZC2
@@demolitiondavedrillandblast Thanks Dave. The ancient Egyptians could have done with some of your equipment, especially this stuff. They got by pretty well with wooden stakes but google won't tell me what type of wood they used.
There is more than a few things that we are yet to learn about their methods.
drill, mix, pour, break :)
4 easy steps - yeah right...
If they’re going through all that for a single residence it must be phenomenally expensive to build in that area.
Oh... no, this is a subdivision for about 14 lots one Acre each. Yes, it will be expensive here, nice area, more than $1,000,000 land value alone.
Is the cracking agent lime based with some additive to aid carbonation like maybe soap?
Yes, mostly quicklime and several other minor ingredients.
@@demolitiondavedrillandblast good to know. thanks dave
Contains calcium oxide, ferric oxide, aluminum oxide.
@@demolitiondavedrillandblast that is interesting. they don't add silicone dioxide aka "sand" but instead use other type of "sandy" ceramic oxides.
@18:15 if they replaced the chisel it might work better that chisel is too short and worn out.
Thanks.
Which creates more force? Hydraulic or chemical?
A good question to which I'm not really sure of the answer. I would think that the hydraulic splitter wins here because its force is only acting for the depth of hole that is equal to the length of the wedges (450mm) and If I were to use holes only that deep for the chemical I would not expect as much action.
A pH of 13? Wow, that sounds evil.
Sure is if you get a splash in your eye or dust in your lungs. I once used a glass jug to pour it in holes and it etched the surface of the glass!!!
Mate, what’s with the PPE, here in the US, we just enjoy then silicosis.
Happen here also.
Pity you can’t use explosives for all of this, would be a lot quicker and give better fragmentation, you wouldn’t need the breaker to get the rock out. The last section shows how effective it is to use explosives.
Did you get your drill bit back?
Yes, very glad about that as it was brand new.
nice barrels :)
Thanks!
Did the drill bit live to drill another day
THIS
9:45 Wouldn't it be more productive if you laid a mat on top of the rock, then the dirt? Wouldn't that make the rock easier to remove after the explosion, (minimal dirt mixed with rock?) And at 21:55, imagine in a few thousand years they'll be scratching their heads wondering how that was done.
I have a heap of light weight blast mats, but I need to bring them to the job on a truck which costs money, the soil is already there and I can do much bigger shots than I would if I only used blast mats. 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. Another bonus of using soil is that I no longer spend my weekends repairing blast mats.
In the past, prisoners made big rocks into small rocks, and didn't get paid for it, i am glad to see that you get paid for it !
Yes... I stopped doing it for fun a very long time ago.
Cracking good trench for the sewer Dave. Just as if you'd used a circular saw.
They started out using a "circular saw" - biggest diamond saw that I have ever seen - 1.8m blade. However it only cut a maximum depth of 700mm and was painfully slow.
Hello Dave, That cracking goo is awesome material!! The trench cleaned up perfectly! Any complaints from the house? That huge excavator jack-hammer probably did more shaking than your boom-booms!! You didn't show us the results of your orange tube!!?? Banana or straight? Great video - as always!! Thumbs up! Stay safe! Jim
The house was empty and owned by the developer, all good, no damage. The drill rod came out unscathed, glad about that as it was a new one.
@@demolitiondavedrillandblast A hole out from the drill on either side filed with expanding agent would reduce the risk of damaging the drill all be it slower.
@@demolitiondavedrillandblast It's always the new ones that get stuck, or bent . . .
Nice clean clear camera shots it appears to me at 720p. Even the hand held ones. Pretty smooth for an old guy that's hugged a drill for the last 40+ years.
I have used that technique many times Rex and I would have done the same here if they did not want to blast today.
@@demolitiondavedrillandblast Liquid Nitrogen filled over with HP H2O
Try a loop of rope over your air drill handle. Then put your foot in loop. Keeps you from looking like, well....
Yeah... have tried that a few times and found that I loose control of the drilling direction very easily and I end up with cramps in my feet.
Needs a longer probe (that's what she said) on the excavator jackhammer.
It was longer not very long ago, don't last very long when working in this stuff.
....only $10,000 fine to repair fibre optics....
Ahhh.... did a job across the road about 10 years ago and the contractor moved the cable himself because Telstra were weeks away... Unconfirmed fine was $40,000
But, did the drill rod come out ok???
Sure did, all good.
Looks like the intestines of a giant that has become a Mud Fossil.
What explosive are you using?
Orica Senatel 32mm packaged emulsion and ANFO.
@@demolitiondavedrillandblast cool!
Not a mask...full face negative pressure air purifying respirator or respirator for short. Just like a barrel is made of wood and a drum is made of steel or plastic, a mask is for solids only and a respirator is for purifying air. But I know what you meant.
Why wouldn't you want to use explosives for every job great, or small?
Maybe I've watched too many episodes of Ordinance Lab.
The rock that I am filling with the chemical cracking agent is right up against a fiber optic cable and that did not want to risk blasting it.
Did the drill come out?
Sure did and it was OK.
👍👍
1:02 - What is wrong with these telco cable installers? That's bullshit.
Hey... this one is in a conduit - that is not always the case for fiber, it is often just buried in the ground - yeah, I kid you not!
You can charge more wearing the gear
pH 13... "part of this complete breakfast"?
It has a strong Lime flavor.
make nice headstones
👍
Talk about Demolition Derby - My Ass simply put is Dynamite
hmmm no explosives?
well... only a little bit later in the video. Thanks for watching.
You shouldn't beat yourself up about a gimbal. The footage looks like a guy filming on a work site. Nothing wrong with that. Most of your work is very acceptable and some is really nice considering what you use and where you are using it. Mud and things that go boom aren't exactly friends of high tech/high value equipment.
Those plots must be really expensive after all the prep' work required to get a house built there. Is it a desirable neighbourhood?
Regards from Scotland.
Yes, very desirable spot to live, 14 one Acre lots, land value would be high side of $1M
Where did they get these digger “operators”…..
you need a license for the goo down there Dave, up here the excavating contractors do goo jobs! i don't see how that stuff works it seems to me with nothing holding it in the hole it'd just push up out of the hole and do nothing!
No license required, not classified as dangerous goods. The goo first hardens and then expands.
@@demolitiondavedrillandblast still with no tamping you'd think it'd just boil out of the hole following the path of least resistance!
It hardens first
@@demolitiondavedrillandblasti get that but still you'd think it'd act like a gun barrel!
