How to do a Wrap around extension, difficult foundations part 1
Вставка

- Started a wrap a round extension, in this video I have started the foundations and have experienced very difficult conditions with thick concrete existing foundations that I have to break up. We pour the concrete using a pump and start with interlocking trench blocks. #bricklaying #construction #concretepumping

Thank you so much for putting these videos together they are brilliant, amongst the best groundwork videos on UA-cam. Have learned a lot from you and look forward to putting some of it into practice myself when i can start on my own project
Brilliant video 👍 great to see your work and one of the reasons we have full confidence in your experience and what you do. Looking forward to you doing our extension!
Beautifully explained as always👍
if you're into buildig or not these are really interesting. you make it look easy although i know there's a dam lot of work and setting out to achieve this.
Nice work Chris! You're gonna have to give in to the norm and get yourself a rotating laser set soon bud 😊
Hahaha yes I have lol, next vids will show us using one I purchased for the job👍
Excellent video 👍
very good video thanks
Excellent job
Wowzers, what a job matey...looking forward to the rest of the build. Keep the explanations coming cause they're really helpful👍🧱😎
Trust me, it'll be good, I was there.
Great stuff Chris , extra time taken on the prep saves so mush time in the long run .
Those T & G trench block are the best 👌🏼🧱👍🏽
Thanks Steve, yes prep is worth the while. The trench blocks save loads of time and give a great base to brick off from🧱⚒️😊 Loving the sun as we’re breaking into the roof. Was over to St Helens for more timber, yay
@@foundationgood123you’re like a local now 😆😆🧱👍🏽
Excelente video 👍 💯👊👌🏻
No wonder Fred West did his own extensions
😝
Great vids. I’ve started digging out the foundation for a garden room which will have an insulated slab floor. Do you think I really need to dig down to 1m for the footings though? It’s permitted development so I don’t need building regs but it is clay. Cheers
Sorry not in the trades so excuse my question. Those trench blocks make things much easier by the looks of it. How will the new building regs changes impact this. I am having an architect at present draw up our building regs drawings for an extension , and they have increased the depth of wall. Outer skin, 50mm gap, 100mm insulation, inner skin. So approx 350mm by my reckoning. Architect did state there was an alternate method that kept wall at 300mm but believed that builders may not like the approach (cannot remember how he described it). Your thoughts?. Thanks
Thanks for the video. Just wondering how much all that concrete you had to dispose of worked out to be. How many tonnes was it. How many 'Skip' loads did you need. I have to do some disposing of a concrete driveway myself, and trying to work out how much it weighs is almost impossible. But seeing how much you had, and knowing approximately how much it weighed would give me an idea of what I need as for as Skip bins. really instructive watching you work.
Thank youJ Jude, there was around 20 ton of concrete, the grab lorry took 18 ton and had to come over for another lift next day. He charged me £200! (cash)Hope that helps
Looking good. So when you dig 1m how much concrete do you fill it with. Is it just a depth up to the top of existing concrete foundations?
I measured down and worked out the block/brick courses and brought the concrete up to that depth, I did that by spray painting the required depth on the trench walls. so it was over the depth of the original fbds
There are lots of factors that determine the footing, mainly the buildings on top of them and the soil. Chris dug a 1m trench and I didn't see any sign of sand or clay, so it's a fairly average footing for a UK extension. To answer your question, it's probably 200mm of concrete adjusted slightly to make the courses work, but ultimately it's whatever your architect tells you to put in!
Nice one Chris. Is the house made from imperial bricks? When were metric bricks introduced 🤔
Yea they’re Imperial, not entirely sure when metric bricks came in, I was using metric bricks in 1978 Im guessing when decimalisation came in which was 1972🤔
@@foundationgood123 Yes that makes sense . Thanks Chris 👍👍👍
Tight on the footing
No mortar between the block? Only that tiny core filled?
They are an interlocking block and don’t have purp joints, the hole that’s being filled are the gaps used for the bricklayers hands in order to lift the blocks and helps to lay the heavy blocks!
Must be fantasic working with your grandson.
Yes, I’m just happy I can give him some good projects to learn from👍

A layman here Chris but a very good explanatory video for someone like myself. I noticed you didn’t connect the new foundation to the existing foundation with rebar (holes drilled into existing foundation, cleaned out and rebar chemically fixed into holes ready to be embedded in new concrete foundation. When is there a need to do this and when is there not a need? Cheers Chris
Good question, the rebar fixed into existing concrete by drilling and fixing with chem fixing compounds and fabricating mesh tied together with wire is generally used if its a raft foundation or if there’s a breach in the foundation! I have done a couple of videos covering this method on my youtube vids. Hope that helps.
@@foundationgood123 Thanks Chris, I shall have a look at those, much appreciated
How come you guys don’t put any trench mesh in your foundations?
Hi mate, nice to hear from you from down under. It depends on the ground and if its on the spec! Ive put mesh in a garage I did recently this was by my choice because of some bushes that were nearby. Hope this helps bud. Enjoy the sun ☀️
@@foundationgood123 no worries Chris. I just know earth can be unpredictable and different moisture contents can play havoc,especially clay based. No sun here mate,won’t stop bloody raining 🌧️ 😹😹
Hire a pecker with your machine would have ate that found and slab
Yes but Travis hadn’t got one in, but we smashed it with the breaker
Exactly how i would do all that chris .impressed with the young lad on the digger there .
Great video and tutorial neat good work.
Be watching more videos.
Good luck Justin @Brickright 👍 🧱🧱👍👊
Thanks Justin, he is my grandson strong lad. We must be from the same time warp😀 Loved your curved wall Justin excellent stuff🧱⚒️

Love seeing the youngsters having a go and to work with your grandson is awesome.
Be falling your videos and commenting from now on .As you say definitely similarities in the way we work id of done that exact same .im still using a dumpy level chris 🤣🤣 good luck to you both mate 👍 👊🧱🧱
