I've only done under pinning once. See if I can explain this well enough. Along the top of the ply, in the middle, that touches the old foundation, cut a 6" square out, as though you want to pur concrete into it. But create a ply box with an open top over that hole. As you fill the box up, it pours in behind the ply and upto the bottom of the foundation. When it's gone off, you just have a lump of concrete to break off where the box was. But it means you filled it all in one go.
Yes mate that makes perfect sense, thank you. Cheers Mee, hope you're well.
Wrong method. He has done it wrong as well.
@@pauldurdan1549 the idea I did was from the structural engineer.
@@Mee10792 Fair enough 👌
Hi i think you are trying to explain a “letterbox”
Doing it that way you can pour in one save the packing after. This is how you would pour say RC column repair
Dry packing always better in my book as if you leave concrete down then any shrinkage in setting concrete is taken up by dry pack 75mm usually.
Also we tend to drill concrete once poured and fix continuity bars T16 then your not catching your face etc on rebar , just my thoughts.
Fair play mate, nice one.
In Australia, we put two layers of trench mesh reinforcing into the trenches, top and bottom. It consists of quite thick rebar. Similarly, we would put quite thick rebar into the underpinning wall. Different countries, different standards!
The number of times i've had to get rid of bulging concrete due to poor fixing of shuttering. Always easy to chisel off the next day . Loving this series.. excellent work and superb explanation of each detail on the way.. well done..
Cheers Asif, glad to hear that you like the explanations, many don't like all the talking! Cheers man.
I love the plank for the cat! ;-)
Plank? You mean the catwalk???!!! Haha! Another person said that in the comments, wish I'd thought of it!
That would have put me right on edge digging away at foundations under the house…great video again
Haha! It was ok actually, all straightforward where it could have been a bum tightingly awkward! Thank you for watching mate.
Couldve just @@mrabuilders6723 I'd've just used expanding foam in thet gap.
Watched a lot of your videosand they're always good crack but nothing has made me laugh more than Adam's tuscan raider impression with that wrecking bar 😂
Hahaha!!! Finally!!! Someone gets it!!!
Just the best building videos on YT. Clearly explained, interesting and at a pace that’s perfect.
Ah man that's a great comment to get, thank you very much. Glad you enjoy our stuff! Take care mate, thanks again.
thought i was watching colin furze for abit there haha good luck lads
Haha! He'd have it filled in and built by now! Cheers mate! Take care.
Construct a "letterbox " to allow you to fill the shutter full!
When I was an apprentice, I can remember a question from my City and guilds exam.... it was to do with when you had a drain fall that was too shallow.... so a 4" drain requires 1 in 40.... but a 6" drain required 1 in 60 fall. As long as the 6" drain goes in to a manhole it can then go back to 4"..... now I've never done drainage for a long time the regs could have changed could be worth checking out
Mr A & the lads smashed it again 👍
Great to see you guys on the same site once again. Keep up the great work.
Another week has passed and that shark still hasn't got you! I'm beginning to think that you've made it up!!! Cheers mate, appreciate your time once again. Have a great week mate.
Haven’t you heard I’m a Beekeeper now.
Wow some serious groundwork great job
I know mate, and it's not over yet! Thank you, buzz. Hope you're well mate.
Nice job, very satisfying work
Nice one, Phil. Hope you're well mate.
Weekend now complete. Cheers to you all looking forward to the progress. Cheers 🍻
Thank you, Brian! Hope you're well mate.
Really impressed with this build so far! Nice work fellas 👌🏻
Cheers mate! Glad you're enjoying it so far! Long may it continue! Thank you for watching and commenting, all the best.
You're welcome Ad , love watching the videos . Keep it up son.
Wow great work with the laser line and underpinning the house
Glad you enjoyed it, Pat. Apologies for the amount of talking! Take care, mate.
Top stuff lads, huge amount of work! great job
Cheers logan, hope you're well mate.
Loving this series.
Even though the videos are 40 mins long, you pack them with such interesting content that I’m genuinely sad it’s over and excited for the next one.
Hope the next vid is coming soon!
Hello Marcus, apologies for the mate reply. Really appreciate your comment mate and I'm so glad you enjoy our stuff. I know I waffle a bit and the videos are a bit long but there's a lot to get through! Sorry mate! Thanks again.
Cracking job in a mucky spot, gentlemen! Thanks for sharing all the details!
Thank you Declan. No problem at all! Take care mate!
Down south , we say its bang-on... fantastic episode 🎉🎉🎉🎉🎉
Great channel chaps. Keep doing exactly what you’re doing. Learnt a load watching the different projects and it’s good to see people who like things done right.
That's amazing, Lee! Thank you so much for your contribution and for your comment, they both mean a lot. All the best, pal.
During casting of existing foundations. As you do in the video by making a formwork up to 100 mm lower than the underside edge of the existing foundation. On the upper edge of the formwork, mount formwork 45 ° in relation to vertical formwork, closed at the sides with triangular formwork. The upper edge of the sloping formwork must be 100 mm higher than the lower edge of the existing foundation. The constructed funnel makes it possible to fill the last piece of the formwork and contact is formed between the new concrete and the existing foundation. The inclined casting is peeled off.
Exciting to follow the basement project. The formwork incl tage sloping formwork can be made at the same time, so all the concrete kan be done at the same time.
That's called a letter box no need to dry pack no mesh in footing he says the concrete is gone off only on top still cureing for at least 28 days before you build other than that he's ok
Now now, don't misquote me and try and sound all clever...quote me in full please...
Fantastic work mate. Really interesting build👍
Cheers mate! It's a head scratcher I'll give you that!
Top job lads.
Great video and commentary,
Boy o boy you needed to rent some conveyors to get that muck out of the hole and through the passage way.
It's a Bit late now though 😂
May be next time.
Cheers mate. Yes, we've used those before and will again this, site wasn't appropriate for them though. Thanks again mate.
Congratulations gentlemen : excellent work. My lord you, rather your customer, have been very fortunate with the ground. With this winter it may have been a swamp, bog unworkable nightmare.
It's quite unbelievable, mate. It could have been completely different like you say. Thank you, steadfast, hope you're well and having a great evening. Take care.
Another great job boys
Thank you, Mark. Hope you're well mate.
Brilliant as always! Some graft going into this. The cost below ground must be through the roof if you had one.
Can’t wait to see the bay being dropped although scary to watch. Roll on next Sunday!!
Thank you, Don! Appreciate that mate. Yes it's been hard work and there's plenty still to do but it's moving in the right direction. Onwards and upwards! Thanks again mate, all the best.
hello mr a good to see a no drama good explanation of different foundation methods ..... the audacity of that leveling peg on the other slab though ....
I know! Cheeky thing! Cheers Lee, thank you for watching again. Really appreciate it.
@@mrabuilders6723no worries ... seeing the soil type its no surprize they decided to step it the way they did .... didnt look great though lol ......
Top stuff as always 👍
Thank you Jamie! That's great mate! We really really appreciate it.
nice to see the underpinning process done. Living in a london town house foundations are kind of something they didn't do so interesting to know what i might need!
i do a lot of underpinning. theres plenty of risky moves going on here, ever heard of the angle of repose boys? taking risks you dont need to
They are clueless amateurs that don't even follow the structural engineers drawings!😅
Hello mate. We didn't feel like there were any unnecessary risks here at all. It came out, it went in, it's all good! Thank you for watching.
Exactly right, quite a few red flags.
Name two.
@mrabuilders6723 The reinforcing is IMO incorect and inadequate, shuttering is poor and badly constructed and braced.
Site is generally cluttered a particular pet hate of mine.
Great videos as always have donated to such a great cause.
Thank you so much Nigel, we really really appreciate it.
Adam and team
I love watching tradesmen at work
It's supper the content is fabulous. Work ethics amazing. Being a welder/fitter in wales I love watching this sort of content keep it up the finest 🍻🏴
Hello David, that's a great comment to receive, thank you very much! I hope you stick with us and you keep enjoying our stuff! Cheers mate.
5:49...definately that foundation pour was a "job and knock" on the morning of a fa cup final day. Great informative videos👍👍🙏🙏💪💪
It definitely seems that way doesn't it! Although I'd be amazed if they worked on Saturdays! Cheers man, thank you for watching and commenting, we really appreciate it.
Thanks!
Thank you, Jim! That's great mate.
Really good video - I always wondered how that was done 😊😊
Thank you, Peter! Glad you enjoyed it mate. Take care.
Great as ever guys 🤔👏😎
Cheers Neil! Hope you're well mate.
I see you’ve mentioned dry packing in another comment but my structural engineer was fine with building what’s known as a “birds mouth” at the top of my shuttering. If you research the technique it’s very effective and a good time saver compared to what it looks like it took you. Well done mate. Keep up the great videos.
Cheers mate, appreciate that. It may have been more time efficient to do it that way! It was hard work I've got to be honest! Weirdly I quite enjoyed it! Thank you for watching and commenting pal, really appreciate it. All the best.
Came to say the same we call it a letter box
Letter box shutter is good idea, but concrete will still shrink, leave 50mm low and fill with non-shrink grout (5 star) just a thought, do you vibrate your concrete to remove trapped air, for every 1% trapped air = 5% reduction in strength 😉
Hard work to get to this stage. Hope the engineerr got it right with the calcs. All the best for the next steps.
You and me both! Cheers mate.
Evening guys another great video loving this job great content "IT PULLED IN NICE "😂
Haha! Cheers, Rob. Hope you're having a good evening, mate.
@mrabuilders6723 good thank you 👍🏻
As an ex-grafter, it's nice to see others hard at work. Although I do miss the physical exertion, as my belly is starting to stick out more than it should!
New to the channel and enjoying the build.
You need more footage of the cats, though! 😂
Haha! I'll see what I can do! Thank you mate, hope you're enjoying a long and healthy retirement. Take care.
@mrabuilders6723 Ha-ha, retirement would be nice, but I've still got another fifteen or so working years before I can put my feet up...
👌
This is what Sunday evening is all about fantastic Adam👍
Cheers mate! Glad you enjoyed it. All the best.
A raised chute section on the shuttering would have helped with the filling of the concrete and allowed it to fill nearer to the level of the existing footing.
Yes mate, the only issue with that is that we may not have been left enough 'packable' space if that mates sense? Cheers, Ed.
@@mrabuilders6723 I understand about the packing, the good thing about the chute is you can see what level you are filling to and control the amount of concrete being poured, I think you could have filled abit more than you did and had less work on the dry packing. As always there's more than one way to do a job, if your way works for you, crack on.
@@mrabuilders6723 Nothing you say makes sense actually 🙄
I'm hearing ya mate. Appreciate the advice. Cheers mate.
@pauldurdan1549 oh I don't know about that, Paul. For instance, if I called you a total bell fruit I think everyone would understand. Don't you?
Took me 2 years to get round to buying a Heupor laser as I’d never heard of them. Got it now & more than pleased with it, so many uses, very easy to use & improves accuracy every time.
The only problem was the wide range of options. I recommend buying 4D with receiver & tripod as you will find uses for it not considered before.
Looking at this make myself
They are great aren't they!
You won't need disappointed mate.
Strange to see an episode where you do more talking than physical work Adam !! But we know that this job requires lots of mental input too. Not just a walk in the park, far from it. You guys make this job appear straightforward, where most people-including some other YT builders- would fail miserably. You even managed to make the digger driver look cool too !!
Sorry mate! It's been one of those weeks though, lots to do but none of it particularly exciting to enough to film and show! We've got lots coming up that we will show though, I promise! Cheers once again for watching, Woody. Hope you're well mate.
I'm not a builder at all but enjoy following this channel. I like the talking and explanations of what will be done and how etc. It's different to just watching the physical work happening and that feeds my thirst for knowledge. I love learning things even if I don't use them in everyday life.
Fascinating job. Looking at the rebar detail drawing for the underpinning, you're supposed to have bars bent 90 degrees tying the horizontal to the vertical. Otherwise you have next to no bending resistance at the base. Did you put those in? I couldn't see any in the video.
Thanks
Thank you, Rex! Hope you're well mate.
Great content Adam. Love seeing a job done properly. I run my own plumbing & heating business in Solihull. Would love to work with you guys on a project 👊
Hello Sam, hope you're well mate. Yes mate, definitely! Our mail is in our bio if you fancy getting in touch. Cheers mate.
Your best option is to set up a square merchants account. First off, you can use it for your business to take payments from customers via card either via a website link, or on the go on your phone, but secondly you could use it to set up a donations page and square will only take around 1.9% of the payment. It's by far one of the cheapest ways
2nd job i ever did was an underpinning one felt wierd sensation sticking my head under a house footing
It's unnatural isn't it! Don't it will ever not be a little scary and nor should it! Hope you're well mate.
Rich doing his best for Anglo-Asian relations literally made me laugh out loud, absolute peak British problems
Haha! Isn't it just! Cheers man.
Excellent work as usual Adam and good to see Rich and Mick. Was it a sphincter tightening moment when you uncovered the stepped footing or was it expected to a certain extent? I hope the weather holds for you for a bit, it’s been very wet just further south of you. Looking forward to seeing the walls go up. Have a good week! 👍🏼
Thank you Simon, hope you're keeping well. I expected a stepped footing but went found what it was like on the other side, coupled with the fact that the house has a basement, I expected it to have at least some consistency. Even the make of concrete differs across the footing, and also differences in depths...just a tad strange that's all. The only sphincter tightening moments I get from jobs these days is when I put the invoice in!!! Haha! Cheers once again mate, have a great week too.
CRACKING EPISODE
Cheers mate! Hope you're well.
Been followyou guys for a good few years now. Amazing work always. Been looking on YT for 2 years now as i am getting underpinning done this summer. Knew everything you guys were doing there. Shame you guys done work in Yorkshire!!
Did you use C35 concrete?
Keep up the good work.
Hello mate. Thank you so much for sticking with us for the past couple of years! We mixed our own concrete for this one mate.
That steel mesh is doing nothing you should use 1000 mm long 20mm dowels into the surrounding earth, the correct way to underpin is to to excavate in sections as you have done then pour mass concrete to within 75mm of the existing foundation which should be cleaned off when the concrete has cured , fill the space with non shrink grout , the alternative is to pour a concrete footing and use short Acro jacks under the existing foundation and concrete them insitu.
Would you and your team ever consider coming to Scotland to do a new build bungalow? Stirlingshire area likely.
Hello pal, sorry that's a bit too far for us. Thank you though.
Have you thought about ICF and fiberglass rebar ?
No mate, we haven't. Would that be better do you think?
What depth, width did the foundations need to be to for the 2block thick wall please?
Direct bank transfer. You can just publish it at the end. setup a separate charity bank account
that ree bar looks a bit to thin
If you drilled a large core hole from the top of the foundation at an angle The concrete would be up to the foundation in one hit.
Probably too late now, but when you set out the new corner of the extension with laser, how do you know that you were in line with the edge of the existing house? I can see you formed a right angle meeting the house and the blockwork, but it could be running in or out and not be sitting on the true corner.
I enjoyed the video. Great work
If the laser is giving out a perfect 90⁰ angle then lining it up with both walls perfectly can only mean that the corner is in the right place. Hopefully that makes sense.
,Your correct if the laser is moved left or right you can still hit both corners,but you might not be in a straight line with existing house wall.
Great work and fund raiser, yes indeed google want their cu£ all crowd fund's usually do.
Have done similar fund raising, money collected early was invested in premium bonds by the time the money was needed had a significant amount of small winnings.
Good luck !
Nice one! That's a great idea!
Iirc, some outfits like JustGiving have the option to include Gift Aid - a tax rebate towards the charity for the tax paid on the donation amount, so a basic rate taxpayer (say 20%) gives a tenner, the charity receives £12. Great video
Thank you, Sarah. Appreciate that.
nice
Cheers man.
do you know the thickness of the original basement walls? guessing they just made them 9inch thick like the rest of the house?
When under pinning we leave a gap of 75mm-100mm for the dry pack are u planning putting more concrete on top of what you have poured?
Yes mate, of course. I think that's explained in the video?
Is it worth keeping them old bricks from the bay when you take it down.
Hello Jonathan. Possibly mate, there's definitely a market for them. Just depends if there's enough to make it worthwhile. Cheers mate.
How do you bid a job like this? You can only guess what's under there.
Well done!
I did just that, Bob...I guessed! Haha! Every job involves a hefty roll of the dice, I tend to try my best and hope! Cheers mate!
It looks like the concrete has simply crept down the hill when it was being poured no?
But the ground missing underneath is a bit more worrying 😕
I've no idea why it's like the way that it is. It's not missing anymore so there's nothing to worry about! Have a good night, mate.
How does revolut work Adam
I will x
The comment might be a bit late, but RUclips have a 'Giving fundraiser' option where RUclips don't take their cut. You might be able to use this (and it get highlighted on the video links)
I love the open air kitchen. Very Mediterranean for the black country. 😂
Haha! There's nothing wrong with an alfresco espresso and a croissant at elevenses! Cheers ross, thank you for watching. Take care.
The footing looks like a knob holding a gun. I think that was the joke on you from the original builders. 😂😂😂😂😂😂
Haha! I can't understand that now!
😂funny that!
Isn’t that what they do when they dig out a basement when the head height is lacking, except in this case you don’t have the first floor overhead!
Yes mate, that's it in a nutshell!
Can you call that thin mesh rebar? Looks way too flimsy to offer any strength
Well it's reinforcing mesh, so it's got to do something!
@@mrabuilders6723 You're the expert so I'm not arguing with you. It's just far thinner than the re-bar Americans use when they pour concrete, their stuff looks like it would cope under tension.
Bostin ar kid. 👍
Cheers Bob!
no dry packing ?????????????????
Hello Martin, hope you're well. What do you mean please, pal?
I'm baffled. Why would anyone expect that foundation on sloped ground to be the same level as the lowest point? Of course you'd expect to find exactly what you found - a stepped foundation.
Surely you meant to say stepped and the same thickness…..
I expected a stepped footing but went found what it was like on the other side, coupled with the fact that the house has a basement, I expected it to have at least some consistency. Even the make of concrete differs across the footing, and also differences in depths...just a tad strange that's all.
PayPal friends and family I think would be free not 100% sure tho
I'll look into that, George. Thank you mate.
set up a GoFundMe
Is that the answer, do you think mate?
@@mrabuilders6723 i think thats going to be your best option, its usually the go to platform that people use when they want to donate money to a cause. i have seen a few popular RUclipsrs using it to donate to homeless people and other things like that.
@@mrabuilders6723 yes i would say so, ive seen a bunch of content creators using that platform to raise money for people.
@@mrabuilders6723 absolutely, this is what other content creators do
@@mrabuilders6723 yes mate i think its your best bet.
Ooh first time I ever got the first comment I think 🤣
Haha! Congratulations, you win this week! Hope you're well mate.
Can you do something with sound, your video are too quiet .
I don't think I can get them any louder mate.
@@mrabuilders6723 I see you got the mic attached - which is great. Can you amplify the sound in some software? unless the mic is not good enough.
If you contact you tube and tell them it’s a charity raising money they will kn ock there cut off many Chanel’s I subscribe too do this !!!!!!!!!!!!!!!!!!!!!
Really??? I did not know this! I'll try that straight away! Thank you!
It's an interesting build but less yam yam and more videos of the work would be good
Sorry Gray, but this is the way we like to do our videos.
@mrabuilders6723 it's all good mate fair play for taking a job on like that
@graycox64 nice one mate. Appreciate that.
Christ you know how to talk, watched this at 2x speed and it was still a drag
You're right mate, I do. Being doing it for as long as I can remember. A view is a view mate and yours is greatly received. Have a great evening.
Nominate the charity of your choice, tell everyone the charities web site, then folk can go there and donate directly.
The problem with the utter vast majority of charities, very little of the money gets through. It's swallowed up in wages, fees, costs, running vans etc..
Exactly, Me, which is why we don't want to go down the whole charity route which is why we've chosen to personally buy presents for the kids at Birmingham Children's Hospital at Christmas, that way in no way can a single penny go to anyone or thing other than the kids.
gofundme
Cheers mate.
FFS please improve your sound quality the volume is too low even when I set my chromebook to full I can't hear you!
I'll try my best mate. Sorry.
Go fund me don't take anything to my knowledge
Thank you, Becca. I'll have a look into that. Hope you're well.
@@mrabuilders6723got the 2 mixed up its go fund me
You have not underpinned as per engineers drawing, nothing like it!
Show the construction Key notes.
You are lucky that lot isn't on the floor.
Oh and not that it matters that clay pipe is broken behind the socket, so you probably broke it when digging out. I have never heard so much b...sh...😅
Hello Paul, good to have your beaming smile and radiant, infectious positivity back again. You're totally correct of course, we've dug more out than specified and put in way more concrete. Well spotted. If there's anything we've done wrong however which will lead to the house falling down please be sure to put it in the comments. Just remember that I said "wrong", if we've done it differently than you would then no one really cares. As for the pipe, I really don't think we did but I can't swear to the almighty that we didn't. It'll be extremely strange to do all that digging around the pipe and the only damage is a bit of mortar to fly out of a joint without so much as the glaze of pipe to be slightly flaked off, but who knows?! I just mentioned it as a visual example of what could be causing damage to areas of peoples homes. But again, who cares? That pipe doesn't exist anymore, bit like your beaming smile and radiant, infectious positivity. Thank you for watching, Paul. Hope you're well and having a great night. Take care.
@@mrabuilders6723 😆😆😆
Well said.
Yeah agree with the guy who said PayPal.
Cheers lee, I'll look into that mate. Nice one.

I'll look into that, Twig. Thank you very much.
A ‘100% Donation Policy: most muslim charity. ie every penny goes to the cause - uwt, Muslims in need
All money raised, every penny, will go to the kids that happen to be in Birmingham Children's Hospital in the form of Christmas presents. Where the money is going isn't up for discussion.
