Close Proximity Blasting

- The plumbers were trying to dig a trench beside a home for an agi drain when they came across some very hard rock that would not surrender. Fortunately one of the guys knew who to call for a fast and effective solution. Demolition Dave has done many many close proximity blasting jobs like this and was able to break the rock and not the house and get it all done without any complaints from the neighbors.

Gotta love a builder that doesn't think about drainage before building the house!
I have had this one doing jobs for people.
How come there is always money to fix a job afterwards, but never enough to do the job properly in the first place?
There are several reasons for this.
1. The house appears cheaper on paper for who ever is getting it built, because the drainage isnt included and thoes who is getting the house built dont know any better.
2. Who ever gets the house built dosnt have any more money, they spent it all on the house and desides that the surrounding things like garden, fence, driveway and drainage can wait.
But it a good thing for the builder to cut out around the rocks for the retaining wall .
Gotta love a keyboard warrior who can’t comprehend homeowners who have modifications to existing homes that might require the addition of a new drain…
Great video of close in work with low energy charges. Perfect mix of content! Well done Dave!
Hello from America! Love your channel and thanks for posting your awesome content! 🇺🇸🇦🇺
Hey, thanks for tuning in and contributing.
I think the dog was replying "all clear". Thanks Dave and Merry Christmas.
Great to see you again Dave. Good work in a tight area.
Wishing you and yours all the best in this holiday season.
Thanks for the well wishes, I'm not really planning any holiday, just keep working when work is available.
Dave.... job security... there will always be hard rocks in the wrong place that need to be 'gone'... and you have made it an art form... cheers
Slick work, as per usual! Thanks for being willing to share this kind of content.
Thanks for watching!
Nice fun little job , The excavator operator is good . Great film Dave.
He was very good.
Love the idea build it first and then worry about water removal. Merry Christmas Dave to you and the misses and family!!
You don't need to be a genius to understand that when you build on a hillside there will be water issues.
Thanks Dave, it is great to watch your videos and hear your voice, a tough job indeed. Take care buddy.
Thanks for watching Jake.
Good show! Thanks for taking us along.
Thanks for watching Paul.
Dave great channel! takes me back to my youth working on the big jobs up north.
Good work Dave, and that excavator operator is not too shabby either.
Nothing like a small job to be a big challenge. Dave overcomes again.
Wow - tight work! Nice job Dave. :)
Not the sort of work that I chase.
The greatest secret in WW2 was the proximity fuse.
I learned this very well from my spring meister here in Germany.
Very important as in the battle of midvay.
Fair dinkum Dave.
The biggest achievement of the proximity fuse was making it to withstand the G forces.
@@demolitiondavedrillandblast the next big thing Dave was millisecond electronic detanotres from Davey bickford.
As soon as it could be fit a microchip in a detonator tube. Like a mobile phone.
You can control shockwaves, fragmentation and more.
Makes lots of sense, especially with large case blasting. Ie coal and copper.

Correction. Instead of “like a mobile phone” I think you meant “like a Lebanese pager” 😜
How do they know to burry the rocks around the corners!!
😄😁 Thanks, Dave.
They were everywhere on this site.
Damn, talk about close quarters to work in. Well done Dave!
Indeed, not the sort of work that I chase.
Hi Dave, Good to see you again! Small booms for a big effect! Stay safe in your summer heat! Thumbs up! Jim
Thanks Jim, We have Thanks for watching, we have 41c (106F) forecast for Monday, needless to say I wont be drilling.
Hello from America! Love your channel, and thanks for posting your awesome content!
Hey! Thanks for tuning in again.
we missed you!
Shucks...
Precision work, as ever. As soon as I heard those multiple shards scraping against the shovel, it was clear you'd done the job cleanly. Happy Holidays, Dave.
07:00 here in the UK 🇬🇧. Perfect start to a Saturday morning, coffee in bed and Demolition Dave.
An awkward little trench to have to work in Dave.
Thanks for joining us Bill.
That was a tight spot, good operator, I'll bet the builder knew about the rock but didn't say anything to the client.
The home was build quite some time ago and the new owner is fixing up damp issues.
Dave, Merry Christmas and Happy New Year! I was curious if you ever have used all electric drilling and hydraulic splitting? This job seems like a lot of manual stuff more than usual anyway!
Electric drills are seriously lagging on the power to weight ratio.
I love the sound of steel on rock. It sounds like money.
I can see the drill heads disappearing as I drill each hole in this very hard rock.
Hi Dave. That was a tight one, but successful as always. I still miss those days when you were in forest/jungle and watch the raw power of the explosives unleashed. However, work is work, and we all have bills to pay 😂. Thanks for sharing. It's getting colder here in the UK, whilst it's getting hotter "down under" 😁.
Wishing you and yours all the very best. Cheers.
Hi Mr. Lamb, nice to hear from you. The Greens killed the logging industry here so there's no more forest roads being built. Getting warm here, 32c today and 41c on Monday! Needless to say I won't be working on Monday.
Dave, where have you been? Missed your videos. Hope you haven't been ill.
But those tiny diggers have been a revolution.
Chris G (LetsDig18) has been testing out a little Micro-excavator over in North Carolina, USA. It's very interesting to see how these little machines can be very useful for jobs in tight spaces, etc. Much rather use them than a manual excavator (a shovel). Take care!!! happy Summer.
Two vid's in short order. Nice one Dave. Regards from a somewhat chilly Scotland where we've been down to -8°C these last couple of days.
-8c I could not exist in that temperature.
Expert in action! This would be the job that sorts the men from the boys (technically).
Howdy demo Dave
Howdy doody Tug Boat.
This job needs a mini tipper truck too.
doggo beeing helpfulLOL thank you for the video dave
Yeah...
He built on solid ledge or as close as he could to skirt the ledge .Nice shatter charges
Tight little spot Dave. You almost had to take the rollover cage off the Yanmar to perform a swing.
Yeah, it got a bit close to the brickwork.
How much of that 25mm emulsion stick did you put in the hole? 1/2? 1/4?
Do you think even just a little ANFO (1/4 Cup/ hole) might have helped lift the rock up without undue vibration? Thanks!!
1/4 max ~ 25 grams, ANFO not required.
Do you ever use sand bags?
No
MM77 Approved 👍🏼 👍🏼
that's not an excavator, that's a hydraulic teaspoon.
Bingo!
It seems brave to go to the trouble of digging that trench without probing it for rocks first.
It had to be done Jim.
How about building a whole substation under existing high tension wires, before finding out the 4x4x6m holes for the new high tension tower footings were in rock not soil. Now THAT person took a risk, don't think they called them "brave" though...
434 👍's up Demolition dave, the most explosive man on youtube
Thank you for sharing 🤗
Thanks for tuning in Scott
How was china?
It was amazing! Did you see the TH-cam video??
@ yes mate! Looks like you walked into a different dimension. I wanted to see diffed diggers on the market particularly minis.
👍
i'm kind of surprised you used emulsion over here they ted to use the heavy 400 grain cord for jobs like that.
25mm emulsion is fine.
@@demolitiondavedrillandblast 25mm i thought you said 35mm!
I normally use 32mm
if it wasn't a trench I could see using expansion compound instead of blasting.
I chose to use bangers because it can still be quite difficult to dig out rock that have been broken using the chemical when you only have a small digger.
@@demolitiondavedrillandblast That's what I figured, and the rocks barely being out of the dirt making the chemical less effective as well. hard for it to shift rock held in place by soil.
Correct!
Går fint det där…
Thank you.

Go to bed!
Not really hard to do if you keep the charge weight down and the frequency up. Done it many times.
You got it, biggest bang here was 25 grams, this rock is extremely brittle and smashes easy.
boom
Just small ones.
✋🏼🇦🇺👍🏼
That was difficult with the house and wall so so close. . In the old, old days the miners would build s fire to heat rock then quench it to break the rock. I wonder.... on any little jobs have you tried a some thermite to get it way hot, them water hose the rock??. It will make superheated steam which is very dangerous Please dont scald yourself, very dangerous>, but with lots of diirt cover and mats it might work well.and no explosions... maybe ...... Have you ever been drinking too much and tried that ?? Who knows, maybe the old ways will be new again ..........But I would stand way, way back under cover.
...
That is a very slow way to do it. A long time ago I have a very bad neighbor who had a nasty rock problem and I chose not to assist him. He worked for weeks using this method, he would build a big fire on the rock and then tip a wheel barrow of water on it. Pieces would fly of in all directions.
