Thank you for the compliments. I could agree that this could be overkill, however NZ is subject to frequent seismic activity and I don’t want to have to redo the work in the future if I can help it! I’m also basing the construction on local building code, and using this project as a trial-run for my upcoming workshop build, as this method would work well for a taller structure.
holy shit your content is amazing, I thought you had 839 thousand subs, not 839. Consider me the 840th. Wonderful relaxing informative content. I wish you happiness and health in this new chapter of your life
As far as I know, in reinforced concrete, the rebar functions under tension, while concrete works under compression. Rebar is designed to work efficiently in tension. However, in the video, the lower rebars are bent at a Z-shape and may not function optimally under tension
You’re right about the rebar working under tension, and that concrete can only resist compressive forces, however my understanding is the Z-shaped bars in the base of the footing should function perfectly. The horizontal portion of rebar gives tensile strength to the horizontal concrete footing resisting the vertical loading from the wall, and the vertical section of rebar will function the same way as the rebar in the blockwork, to resist the horizontal load from behind the wall. Additional strength is gained by the vertical and horizontal sections in the foundation being continuous, so the forces applied to one are transferred/shared across another plane. No matter which way the structure wants to bend or rotate it has resistance to both tensile and compressive forces. I think a stepped foundation like this would be far stronger than a ‘flat’ continuous footing.
The outer skin of the wall will be old imperial clay bricks. I’ve used them in the layout to plan the finished curve, so that the blockwork ends up in the correct place. Check out the Part 1 video, where I show a computer generated image of the walls construction. The notches in the concrete are steps for the brick skin, so their foundation is below the level of the driveway. I only needed those notches because I decided last minute to thicken the foundation to 8”.
It’s a 40kg (88lb) bag, so the mixer can’t take all of it at once as the mix would be over 500lb! Didn’t have too much spillage although usually I’d have the bag closer to the mixer if possible. Thanks for the comment; maybe I should buy smaller bags of cement….🤔
The TH-cam algorithm is a fickle thing for sure. I don’t know what the answer is, just keep making the videos whilst you still enjoy doing it. I’ll check out your channel.
Compliments on the high quality editing and voice work on your video. Do you not think this is all overkill for such a low retaining wall?

Handwork and voice acting are on the level! This is magnificent educatuinal video.
Thank you for the kind words.

Thank you for the well wishes, and the subscription- much appreciated. The channel is still in its infancy,🤞for those 840K subscriber numbers!
I thought the same thing!…awesome content.
This guy is awesome!!!! Hope your channel gets the attention it deserves
Me too! Thank you for your kind words.
That's a lot of work mixing the concrete like that. Wow
Tell me about it! It’s good exercise and nice to know you’ve done all the work yourself.
You mean, the cement mixer did all the work
That’s really made my morning. So satisfying Dan. It’s a shame you had to cover up that perfectly dissected archeological dig site Indiana Jones.
🤣🤣 don’t worry Peter, there’s plenty more projects involving excavations to come. Just wait till I start building the ‘Hobbit hole’’……no, seriously!
Loving it.. Love it even more if part 3 was out tomorrow 😁👍
👍Thanks for the comment. Starting the block work today, so part 3 is underway! 😀
@@danwaterson356 woo hoo.! 😄
Great Job
Thanks
6:40 C'est un superbe outil
Merci. Regardez la vidéo où je l'ai réalisé. I made it in this video- th-cam.com/video/qTNG0n7XhPw/w-d-xo.html
Nice work.
Thank you.
Happy easter - so good. 👍
Thanks, and happy Easter to you.
Quality stuff
Thanks
Lovely video mate. Looking forward to part 3. Will you be doing other videos in future?
Thanks so much. Yes, if the videos continue to be well received I’ll keep making them. I’ve got so many projects planned it’d be a shame not to share!
Really good video thanks
Cheers

How many bags of cement did you use?
From memory it was around ten 40kg bags of cement for the footings.
What were the bricks for in the concrete work, what are those notches for?

where you from Dan 'Lancashire ?????
A little further south; Staffordshire.
Why not just cut the cement bags in half instead of shoveling it? Save time and spilling it, great stuff tho!

how can I join you am also a builder.
Thank you but I’m just taking a year away from my job (or maybe longer) to work on these projects at my own pace. All the best
I like your content and we do similar projects at the moment. I also think we get less views than we deserve given the quality of our videos.
