"A" for effort on the part of the homeowner, but he brought a knife to a gunfight. The right tools for the job - a bigger drill and those hydraulic splitters, plus the skill and experience to employ them effectively, sure make it look easy. Nicely done DD.
A few strategically placed holes, a lot of pressure in the correct spot and the job is done. That takes skill, knowledge and experience. Job well done Dave.
Watching this I must take my hat off in respect for all the civilizations that built huge stone cities with impressive sized blocks of stone. They cut them out of quarries and transported massive blocks hundreds of kilometers to place them to build temples and pyramids which many still stand today thousands of years later. They had nothing but stone and copper hand tools. Drilling holes in solid granite as well as softer stone and then breaking them into blocks. They still aren't sure how they made those blocks so smooth and square that it is impossible to slide a piece of paper between them. I think many of the of workers died before getting to see what their work had accomplished.Many of the cathedrals in Europe took hundreds of years to complete and were not as massive in actual rock but still a major undertaking.
@@demolitiondavedrillandblast I threw my TV out the window one night in 1986, when I realised I was watching "Prisoner, Cell Block H" after coming home from the pub. Haven't had one since.
Beautiful looking rock. Where I live in southern North Island, the only rock we have is sedimentary - Sandstones and Mudstones - and I look with envy at your Granite!
Dave, always checking in on what the other guys are doing. I've done a few of those also. some split, but always found blasting so much more effective.Try a 2' hole on a 1' x 1' b/s ratio. Use an ounce of high speed/high pressure powder. Kinestik is super easy to transport, and really efficient. Throw a couple of 3' wide conveyor mats over the top. Double thickness 2' around over the collar. Low PPV. Wish I had as much patience to video my shots. Way too busy. Thank you for the entertainment.
I almost did blast this one Mark, there were 2 issues that tilted me toward the splitter, 1/ A concrete pad footing resting on top of the rock. 2/ The support column on top of the pad is supporting a tiled floor above - very easy to crack this one. I have done quite a few jobs just like this one in the past, using explosives and big woven rubber blast mats. But yes, 1 oz is about a 1/4 of a 25mm x 200mm slug of emulsion and I would have to be very unlucky to cause damage with this. I have heaps of old blast mats that I rarely use these days.
@demolitiondavedrillandblast Nice touch! I didn't realize you brought in the fan for the fumes..........but I should have! Very professional!! They were lucky to get you
The secret to successful less labour work is correctly reading the rock. A skill Dave has developed and one I had no clue to when I did something similar. The final shots reveal how much Dave has invested over time to get to a position to be able to successfully undertake such removals. Just one portion of the arsenal.
Hey Dave, Glad to see your still hard at it. Hell of a Rock, Not sure why but I like hearing the rocks " Pop" I guess maybe that you have won a little bit against them. Thanks for sharing Dave, Always look forward to watch your video's.
✋Umm, there's an excavator UNDER some guy's house. When this makes economic sense, you know the housing situation is stuffed. I can see why people want to live there (especially now). But, holy cow, I'd have to retire at 106 and live in a tent in the bush. I hope you've had a pleasant winter, Dave. Thank you for sharing some of your jobs with us. Cheers from North Carolina, US.
only way to get a house is to wait for family to die now rise in single mother homes and child free couples no generational wealth is coming then add importing of cashed up immigration where every one helps young couple buy house over seas know there kids kids are set.
My parents did a similar project to their house back in the 70s. Created a great big Rumpus Room the full depth of the house. Fortunately, they were able to design in the room span to the floor above at the time of building. It would have been a nightmare of a job if it had stumps and bearers in the way. This is an efficient way to gain extra living space at minimal cost and without increasing the size of the house footprint. Mark from Melbourne Australia
Dave could you tell us a bit about how you operate on a daily basis. Where do you get the explosives. How you transport them . The restrictions on them. What happens to them at the end of the day. Obviously just in general terms for security reasons. It’s just not like your average box of tools a tradesman brings home. I would also be interested to know the prices of some of that equipment. None of it looks cheap! Anyway you do a great job and I love to see something I would never get a chance to see in real life. Keep up the good work.
Thanks for watching John, this splitter is a Chinese copy of the German Darda splitter. Cost me about AU$12000, personal import. The German equivalent is ~ AU$70,000!
You could at least have drilled another 13 holes to get over the 3K number Dave! Lazy sod! Must admit that those hydraulic feathers, although not exciting to look at do one excellent job. Thats going to be one huge space for your customer.
Any reason you didn't use the expander form Dave. PS Come on fans of Dave with 4000 plus views at time of viewing yet under 1000 have taken the trouble to give a thumbs up.👍👍👍👍👍👍
Those cracks are so satisfying Dave! What sort of $ do you have to spend on one of those splitters? They look expensive! Who tried the Expando first - the homeowner or the builders? I used it (with your guidance - thank you) and was so impressed by how well it worked. The key, as you said, was hole depth and diameter. Took forever to drill with my electric Bosch and a 1-1/2" drill bit, but it was well worth it.
Good to hear that your project went well! This splitter is a Chinese copy of the German Darda splitter. Cost me about AU$12000, personal import. The German equivalent is ~ AU$70,000!
well that was brittle for granite i expected it to put up more of a fight!! i know one thing i will never get used to seeing the steering wheel on the passenger side!!!
Regarding being brittle, I call this rock Granite but it is actually Granodiorite type I and this is somewhat harder than regular granite, as well as well as being very brittle.
Say Dave, have you ever found gold under any of those rocks? when i high bank at the river, if i find nuggets, i find them under granite rocks a wee smaller than this one, then you know, i watch a bunch of australian nugget hunting videos, they find a lot
The customers excavation plan was going well until a large piece of granite rock was encountered. Undeterred they fired up the internet and found a Demolition Dave video showing how such rock can be conquered using an expanding grout product like Expando. The product was purchased, they drilled holes drilled and filled, waiting, waiting....The exercise was not successful... for all of the usual reasons.... Holes to small a diameter, holes not deep enough and holes too far apart. - Better call Dave
@@demolitiondavedrillandblast Funny you should mention that. I do a few jobs for an actor just about everybody on the planet knows. Anyway, I was too busy to get to his job. I told them to call another guy. They did. Put the expando grout in, and... nothing happened. They called me back 2 years later to break it up. I started to drill and it and..presto,2 years later, it finally cracked.I was the straw that broke the Camel's back, or my drill was .
Very large 'extra storage' area. Have you ever thought of using a wire saw on some of these? I dunno what granite foes for down there, up here some of these jobs have pieces worth thousands.
I almost blasted it, however the footing for the support column was sitting on the rock and he had a tiled floor above - that was not going to go well.
I noticed ur weather after lunch. Be stormy, esp at ur place. Hi to all. Like exaggeration.... enjoy blowing things up. 😂. This is a jk for those who dont understand.
Those big holes must take some drilling Dave. I wonder if people not from our part of the world know what an icon the Highlux is? Did you have the Bugger TV adverts in Oz? th-cam.com/video/CPYmtEQiG18/w-d-xo.html

Dave Thank you for going thru all the trouble of making these videos I sure do enjoy them!!
Glad you like them, thanks for watching Hank.
I do too.
Watching the hoses jump when the rock pops tells the whole story.
Another job well done by all.
8000 PSI in those hoses!
I love a good shot, but the hydro splitters are sooo satisfying!
The satisfying click one wants to hear when breaking rock unlike the unsatisfying click one hears when wrenching cast materials like engines
Dave, you have the coolest job in the whole world.
Thank you Mr D for sharing this with us -much appreciated
My pleasure!
That must be a HUGE house! Making the US ones look small! Great video as always Dave, love to see when you drop them!
Yes, some large homes in this area.
Got the notification and it brought a smile to my face, love the videos and love a big bang but this hydraulic Cracking is really neat! Thanks Dave!
Thanks for watching and contributing.
Glad to see you Dave! Those splitters are pretty wicked! Digging the music selection too.... Hope to see more of ya!
They are a very useful tool, drilling the 48mm diameter holes is a big task though.
A few strategically placed holes, a lot of pressure in the correct spot and the job is done. That takes skill, knowledge and experience. Job well done Dave.

Yes indeed!
Wow that's hard granite. Nice one Dave 😊
Good to see some splitting Dave! Great job, your dust system is working great as always! Hope all is well!
The vacuum dust extraction system was very important on this job. I also used the ducted fan to remove some of the excavators exhaust fumes.
@demolitiondavedrillandblast Nice touch! I didn't realize you brought in the fan for the fumes..........but I should have! Very professional!! They were lucky to get you

So satisfying when it pops like that!
Amazing equipment Dave great job as always 🦘
Glad you enjoyed it, thanks Kerry, have not seen you around here for a while.
Awesome video Dave
that was great Dave , you could hear the granite cracking over the sound of the powerpack . WOW.

Thanks for sharing 🇨🇦
Glad you enjoyed it, I never get tired of watching it either.
Dave saves the day agan.👍👍👍👍
Always amazing to watch the splitters at work. Tks for sharing.
Glad you like them, I do also!
Hi Dave, No booms - but some nice pops! Homeowner should be happy! Thumbs up! Stay safe. Jim
Thanks 👍
Interesting project. Homeowner adding more living spaces? Thanks for sharing Dave!
Storage space.
That was so cool Dave. Great editing too.
Glad you enjoyed it Grumpy.
Lovely bits of granite you popped out of there for him!
Yes, If I could slab it it would be saleable.
Always eager to watch your videos.
Thanks.
I love watching your videos. Thank You for sharing
Glad you like them!
The proper application of force!
Another great video Dave !
Glad you enjoyed it William.
I love hydraulics and the sound of granite breaking!
Not just you Bob!
Must have been a Huge shock to discover that small underground mountain under his home .
But not for me... when this subdivision was built in 2006 there was a rock about 20m long just outside his front door that I blasted.
What a great way to start a Monday! I do like the hydraulics, thanks Dave.
8000 PSI for this one!!
@demolitiondavedrillandblast whoa! If one of the hoses let's go, it'll be spectacular!
I would guess you have to keep those wedges greased so they don't snap off the hydraulic rams eh?🇨🇦
Yes and the type of grease is very important (and unbelievably expensive).
Cracking Good Job as always Dave.👍

Good day
Gigantic rock must of been an unpleasant surprise when the contractor dug out the basement expansion area.
It is good for me!
Good show. Thanks.
Glad you enjoyed it Eddie.
awesome Video !!!!! amazing equipment !!!
It sure is John.
is that a stuck drill bit I saw at about 12 minutes in? Hopefully not one of Daves!
Yes, Customers SDS Max bit.
Unsure if calling these 'feathers and wedges' does them justice. However, the anticipation of success is much more palpable than blasting.
Exactly, they are hydraulic feathers and wedges, without the heart ache of getting them out when the rock does not fully break.
G'day Dave great video and cool job mate
Thanks 👍
good stone, good weather, what else do you need for professional work:)
Hi Dave👋
Good pay is always welcome also Yuri.

Hi Dave.
What are you smearing on them wedges? must be some kind of extreme pressure grease.
Have a real nice one. Cheers.
The super expensive grease.

Wow, really? Thanks for replying.
do you recall it's name? by any chance.
In any case happy advent new year.

Yes, 32mm holes is not very successful and 400mm deep is nowhere near deep enough.

Hi quick question looks like a 45 by 500 hole for the splitter how long to drill each hole in this rock
The hole is 47 x 550, takes about 5 or 6 minutes of going hard at it.
@@demolitiondavedrillandblast thanks
That excavator operator more worried about his headroom than what the pick is doing.
This is a very valid concern for him, one small bump one the roof and the tiled floor above is ruined.

@@demolitiondavedrillandblastThat's how they started out. Check out the steam shovels they used to dig the Panama Canal!
