Rich is the man and fits in so well with ya guys. Hope he is in videos regularly in the future
Digging out solid rock to replace with a softer concrete to pass the building regs. We have the same problems here in Scotland 🤣
It’s better to leave hard rock and build on it. In the uk when you have a footings inspection they prefer hard rock to stay in place. It’s happened to me on many jobs.
I think they require a certain depth to stop sideways movement of the piles. the rock is all good for taking downward load but if it's only 300mm in the ground, the pile can migrate sideways
That could be overcome by drilling and gluing an anchor in it. But that would be an alternative solution requiring engineer calcs. May as well dig.
"My dad named Tony" 😂🤣
He doesn't have shin's ... Toe - Knee
@@elwinvanwees8516 Sounds like Cotton Hill.....
Getting that concrete under there manually would have been back breaking and a real pain in the arse. You made a good call Scott.
Your Italian? No, but my dad's name is Tony. LOL.
Richard seems like a good dude. It'd be fun to see him on in future videos.
Strange that this channel doesnt have more subscribers with such great content? If I could I would subscribe twice!
David Jonsson I kinda don’t want him to blow up. He’s putting out awesome content right now just the way it is lol
David Jonsson yeah, agreed, me too!
I usually watch, never subscribe. But after reading your comment, I thought I'd hit the subscribe button for you.
People don’t recognise quality that’s why. They would rather watch click bait and fake content from people who just want millions in followers.
I am happy with Scott and his crowd, less drama with haters comments and best content from Scott
His videos are so easy and relaxing to watch. Even if I wasn't into reno's and building I'd probably just watch them just for the entertainment.
You guys work well together funny
Rich on his holes: “I went from this one, to this one, hoping it would make that one easier”. Hilarious.
Scott, don’t usually post but this really is one of the best TH-cam channels, brilliantly shot, great content and entertaining. Keep up the superb work!
Next time you’re in London I could use some help fixing up my house. 😂
A trick for harder rock (or concrete slab) is to drill a series of full depth holes with a 12mm bit on your outline. On bigger excavations a few extra holes in the centre helps a lot. This also avoids cracking concrete (not your present concern). I have done this to pass ventilation ducks in cast concrete, not fun, but not as bad as a break hammer only approach.
As a chippy myself, I get excited everytime i see you've uploaded. Love your content!!
I'm a carpenter in Miami, Florida. I'm planning to go to New Zealand 🇳🇿 and Japan 🇯🇵 to learn new carpentry techniques. I work in high end apartments and penthouses.
Pump & truck were the right tool for the job for sure! 😎👍
Pump truck is usually the way to go...haha. Especially after working so hard on drilling and hammering those holes! Smart!!
Unreal vids Scott really appreciated. If you get the chance to discuss/or come across 'leaky buildings' which was a real issue in NZ particularly Auck - what to look out for, particular types of houses, some of the problems/fixes etc would be awesome! Love your work guys keep it up
Never liked TV to much but this is so good to watch.
Hard work guys. Well done.😎
Got Similar here where I live in Australia lol the foamy stuff here is generally pretty soft,and the hard dense stuff isnt too bad but then you get some that's like a combination,hard but has little soft pockets that the chisel just falls into and traps it. An ezebreak micro blasting system is definitely on the cards here, can apparently be used indoors etc,just an 8mm hole from memory insert the device and pull the trigger
Good call on the concrete pump!
Found your youtube channel about 3 weeks ago. And now i can finally say i saw all of the episodes. Love to learn some new skills from a carpenter. Keep up the good content and thanks
Always a pleasure!
I literally just did this kind of work a couple weeks ago. But three of the five pile holes had to be dug while laying on our bellies and the ground was so wet that the holes were filled with water within hours. And then the concrete pours were from a truck but then bucketed to a guy under the house. 😐 (Fyi, i was not the one who made any of these calls but they all took aaaaaages! Lol) What ‘exciting episodes’ those would have been!
Tough job digging holes in confined spaces .well done boys, great job
easily the best start to an episode ever!
“Scott brown ere”. Sweetest words ever
He definitely still says the H in 'here' tho.
Finn Payton oh for sure, just with a kiwi accent it sounds like ere lol. Scott brown is the man
It is sweet how he sez "deck". Maybe he can release a book with 101 big deck jokes.
PaulusTigana hehe

Other stuff I'd be interested to hear you talk about would be: Lending tools to mates; Go or no-go? How to explain to customers that you may cost more but are actually better value than the cheapest guy/gal. Setting the right "tone" or ethos on the job (some teams have a nasty vibe, some are fun and still get the work done, some are crude and foul-mouthed). How to approach jobs that are "Big Time" but could ruin you if they go wrong (e.g. would you take on weeks of work from say, a national house-building company?), Dealing with "lurkers"; customers that hang about watching you work, Keeping financial records; any tips to make it easy?
Your smokos are absolute quality.
Great start to a Saturday morning
From Iceland love your stuff!
Love your chill style, and appreciate the chill music. Keep up the great work guys!
You play the best music and at right volume of all woodworking TH-cam channels I'm subscribed to. 👌👌👍👍 Oh forgot to mention, so does Eric Sorenson, incase he watches your channel and reads my comment. 😂😂
I'd use a grinder to cut strips into the rock and then use the breaker. The cut lines help concentrate the force of the breaker and helps getting chunks of rock out.
brilliant job well done you guys Paul from the uk
Another great video from SBC !!! I think it’s time for some T-shirts made with Smoko Time on them with the logo. 👍🏻
Drill a bunch of holes with a long sds max bit and then go at it with the demo hammer. Tough digging in a crawlspace!
Your coffee matches the cycle-lane below too... 0:04
Depending on how much you are doing you can often buy the sand/rock (aggregate) from a dump truck and the cement from the bag and that is cheaper but given the labour of getting it under the house the pump was the way to go !
Scott, look into a product called Expando. You use an appropriate drill to drill a pattern then fill the holes with it, wait a day then pull out the rubble. Its a non-explosive demolition product and works a treat. Drilling is far easier than jack hammering.
Man your videos make construction jobs look like vacations.
Use an angle grinder with a diamond blade concrete cutting disk.
Cut slots and then chisel it out
I'd really like to see an episode on how you price jobs. For example, who is covering the extra time for those awkward holes on this job? How do you approach jobs that require a lot of research and time to arrive at a quotation? Do you charge a design fee, deductible from the bill if you win the job? I have been stung several times by people wanting a price for complex work who then walk away or don't even reply to say "no thanks" after I have put hours into working out a spec and price for them.
I love this channel!!!!
Loving the music on all the vids too!
It's always a good day when there's a new episode 😁
That little snack you ate at smoko time was bigger than my main lunch!
Still hanging out for the chimney removal episode
Where I live, Vancouver Canada, if you get down to bedrock, you can pour a concrete footing ontop of it (at least three times the width of the collumn or thickness of the retaining wall) and if you encounter bedrock you can dowel in rebar to tie into it. You really arent going to get a better footing than the earths naturally compacted boulders, hard pan clay and glacier till/lava rock. The only real rule as a bare minimum is 24 inches below grade is oue frost line, and all footings need to be below the frost line. you can put wood into the ground aslong as its pressure treated, and encased in concrete. even then its a pretty big no-no because we get a lot of rain and after 30+ years even pressure treated lumber will start to degrade. So lumber above grade normally, concrete penetrates 24" below our frost line, and if you encounter bedrock or hardpan you're good to go.
So basically what I'm saying is this is massive overkill over here, but I understand the difference in municipality guidelines and restrictions
I solute u man, all the way from Iraq.
Nice art u have out there!
Keep up the epic job!
Coffee and my boy s.b.c on sunday morning... churr👍
I have found the pointy chisel bits not very effective on solid rock or concrete, basically because the chisel is really trying to compress the material sideways. I've used a large SDS tungsten drill bit, drilled a series of holes, then the chisel.
Hope the home owners appreciate the work.
I've just dug a 1200m tunnel under Newmarket through that basalt. Nothing but problems the whole way
Glad to see the concrete in situ. Just out of interest are the timber stumps into the concrete a species to resist decay. (List in the NZ standards).🏝
CCA treated radiata pine.
Been there, done that. 20 min sounds about right; Pump Truck is where it’s at.
Must be tough to be a builder in NZ because it's always bloody raining. Sydney weather is starting to become like Auckland.
Love the Alan watts
With a Hilti that's how. Another great film.
It's be awesome if these were the length of regular films. We'd watch it all day long.
Did a job on rock field rd. In Auckland once.
Found out how it gets its name.
100mm under the back yard was massive van sized boulders of rock.
We ended up bolting brackets to it for deck piles.
Brother from another mother! I love all the video's. Watched all at least twice. Keep up the great work!
Always pour the furthest holes first, if you run out of concrete before your done then you only need to hand bomb the closest ones.
Volcanic rock sucks indeed.. here in Sweden it's all granite which is not much easier to chip away... Btw, nice example with the cost calculation for the concrete pour. Sometimes what seems more expensive may end up being cheaper (and people often forget to account for labor)!
I’ve been told trying to dig just post holes in Hawai’i can be just as bad if your over the old lava flows. Wild that something so porous can be so dense
To everyone questioning about digging out rock, in nz we have to pass inspection by building to engineers specifications so if the plans say 800mm holes to support a certain load, then the hole must be dug to that depth.
Sure but in any other part of the world the requirements on top of solid rock aren't the same as in silty dirt. It just seems dumb to hammer all that out and refill it with concrete doesn't it?
In nz it’s not just about downwards load. We get a lot of earthquakes so the depth is more about lateral strength when the ground goes side to side. Otherwise the houses would slide off their foundations at the slightest shake.
@@livingimprovements4382 not if you epoxy steel rebar into though right?
@@livingimprovements4382 but if you compare it t the old posts, that been there for a 100 years or so, it seems overkill. The old ones just do not look sturdy.
In my country, if you have an Engineer doing the plans for the building. You do it according their specifications. If you go away from it and something happens, you pay the bill. So, ye.
The same rocks here in Hawaii. I feel your pain.
Great video👍
I was wondering
What shoes are you wearing?
Good work mate
The unconfined compressive strength of that Tuff is at least 20MPa which will give you a bearing capacity factor of safety of at least 50>3 therefore satisfactory.
shout out to the hilti reps, cool fullas!
Is it standard to bury posts below grade surrounded by concrete? VS setting post on top of concrete?
Shot boys mean Mahi!! Up the BLUES!! 💙💙
“My dads names Tony”. 😂

My comment:
The material should be made fragile so that the work is easy. If those from Hilti can`t figure out how to save you work (money) they should find a newspaper route !.
I see at 4:23 you use batten screws to connect the top of the pile to the bearer. Is this better than wire dogs?
These hilte guns are very good
I have done this. A pump is definetly the way to go
Hey Scott u should try Freud blades for u circular saws if u havent tried them before :)
Scott’s awesome but gotta love Rich 👍
Do you ever get a chance to chat to the engineer on the Job? We'd usually find a way to get around it if they're ordinary piles, a clean hole on rock would likely be sweet. If they're anchor piles, we could swap them out for braced piles, a diagonal brace and a couple of bolts could save hours... Engineer time ain't cheap, but, if it can save you a lot in the long run.
Hey Scott, another great video. Quick question; do you dig the holes, secure the posts up into the beams, and then pour the concrete around them?
7:39 That man got Paerau's joke.
Right call on the truck. Much better to pump in tight spaces. I'm not sure about the way you dug the holes. I would have looked into core drilling the holes. Especially because it was volcanic rock. Would have been easy with diamond core drills. I'm not sure if you could fit a big enough drill in there. You might have been able to use 150mm core bit.
Hello Scott , are the five holes support the whole house or just the extension?
Cruz ✝️. Yes put more lyrics of songs like this and it’s a big like awesome 👏😎
Pump everytime!
Those foundation post holes are the most expensive holes ever!
Pretty Good with Rich on broad Bro changes the Dynamic up abit.
My first thought when you commented on the best way to get it in was 'pump truck' - no brainer..
Wow that HILTI guy just launched him self in under that house 🔥🔫
The weather in NZ looks very similar to Liverpool UK
Use a darta rock splitter next time. Break it up in chunks and pluck them out. Need to drill a large hole first to accept the splitter.
Hey✌️good work Scott! Which shoes do you use on work? I like them, want them too for my site!!
Have a nice day 🤙
I mixed up just 4 bags last Monday to do a small strip of concrete beside a drain we installed recently. The instructions require 6 minutes of mixing per bag (adding more water after 2 mins). How long do you think it would take to mix 50 bags? Pumpy was well worth the cost.
So where you stay Scott to buy 50 individual bags of cement is roughly the same as ordering premade in a truck plus pump. That's before you add manual costs of mixing and filling yourselves. That's amazing. At what cost per premixed does this become a viable option, like can you only order a minimum of 500 dollars of premix, anything less and doing it yourself is cheaper. Just interested to know man.
That truck and pump was $600
20 kg bag of concrete is $8 so 50 bags is $400 for 1000kg dry which is about 1/2m3 of wet concrete.
To buy 1000kg of aggregate and 8x25kg bags of cement to make 1/2m3 would be about $120.
So the last option allows an extra $480 for labour. So it all comes down to how much you can save as a DIY or pay yourself rather than the concrete suppliers as a builder
Were the piles only for dispersing the the point loads from the beam? The engineer might've let you get away with a small pile or pad instead given it was good ground (rock).
Yes, smoko theme is back. Not sure why I'm so attached to it.
Because you can see how good their snacks are.
Iv had to lay sewer lines through similar rock and I found the best way to deal with it is grind channels and know out .
Mate, smash it into million pieces and then sell them individually through eBay 10 pounds each little piece hahahha
A lot of building companies where I live, save rocks and what not and separate them on the build site just to sift and sell it. So, there is a market for it. Especially volcanic rock in the Aquarium hobby.
Is festool worth the extra money
At least anyone wondering is it a good thing to spend quite a lot of money on a Hilti hammer drill, this videos shows it is. Yeah, I dont trust the more expensive the better.
God, do I need to move to NZ to get this work relationship? I've had one job where we could have this banter. I miss it everyday. Fancy signing me up? 😉
