Single mat wall. Yeah center will work. If it’s a center retaining wall with inside pressure and minimal dirt. Centers ok but putting the steel closer to the water side with the right angle facing the outside. Dirt is heavy but water has more out more horizontal pressure. Air is for expanding in cold temperatures. Mainly for out door pads. Walls do if they are not insulated. You can put foam on outside. They don’t always put air on walls or footers because footers are underground., depends the size . I built water treatment plants in mid Atlantic east coast and desert out AZ . If you mix it your self it’s fine if it’s not the same color but you want a decent slump at a higher psi. It’s getting covered with tile. So the larger you go like pools will need an expansion joints. They have a mold plaster mix with fibers that’s you can make a diagonal mud pad . We done some. But I seen alot done on commercial senior homes and other.

You should only need one ground or run the wire half way around. I’m thinking about it. I built a few pools. I worked for a civil and structural engineer company . I’m good with archaeological drawings because I was a bridge and ctf inspector. My my profession is in concrete foundations, walls, slabs and decks. As well as reinforcing iron, I was a union foreman. I was a subcontractor and now I’m a commercial contractor bidding on my own jobs. I want to see the bonding . If my tub is smaller how thick I need it. I can check the specs for my states code. But they normally run one ground in the ground but run it all the way through. If it’s a big building thry might have multiple points . Grounded energy. But the concrete insulates it. It’s really to pick up the negative energy from the ground . Is my opinion. Copper probably gives it energy like it does with the plants . I’m run copper too my craw space and might put a ground . Add one sonce it’s an older house.
that is a beautiful hot tub! and a great tutorial about the construction I'm currently constructing one myself. doing it all myself to save a bit of money. I can get the wooden reinforcement quite cheap or free by using pallets and off cuts, and intend to use the earth as the outer support and concrete board designed for wet rooms as the inner layer so I have a nice smooth finish and less wood to remove (its nearly as cheap as wood at the moment anyway). its not quite going to be as fancy as that one but honestly I'm hoping for something not too far off but for a fraction of the price once I'm done just out of curiosity, what was used to mould the shape of those curved seats? I've got a size for my hole that will give me a 3m x2m tub with a depth of about 1.4m. I am currently planning out the interior. if its not overly difficult (as in it just takes some time and hard work) I'll definitely go for a similar layout with those curved seats and add an extra couple of jets into the design
Thanks for the comment and watch Oli. For the seats, they used a wooden mould and the design you can find on my site here - buildahottub.com/how-to-build-a-concrete-lounger-for-your-pool-cocktail-pool-spool-or-hot-tub/ If you need any assistance or parts, please do get in touch, cheers - Andi
The maine reason you never hand mix concrete for engineered insitu reinforced concrete structures is, you can never be accurate or maintain the integrity of the concrete mix to achieve the design strength, unless you are using a batching plant on site, a Ransome with strict adherence to proportions of aggregates, cement and admixtures, then you may be closer to achieving the desired outcome. Also remember to use a poker vibrator to ensure the concrete is settled and all the air pockets are removed. Do not over vibrate or you can cause a separation of the heavey aggregate from the concrete mix, causing honeycombing, and fast dehydration of the concrete. What is not mentioned is the difference between a two armored part pour and a monolithic pour. In a monolithic pour, the forms and rebar are placed,.along with any plumbing fix, allowing for a one time pour to ensure uniformity and the need for waterproofing between pour joints, as it would be for a multiple pour structure. You would need to set a waterproof moisture barrier material in the concrete to prevent leaks and seepage. Remember, concrete poured in parts does not join.
Hi Diego, this was a 30K project for the customer in the end as he had a lot of the work done for him by contractors - took about 3 months start to finish. Most customers build well under $10K to give you a ball park figure - this was a complicated setup with a lot of kit. Hope that helps - Andi
Hi There, this build Kyle used a lot of contractors and ended up costing just under $50K. This was half what he was being quoted by several pro pool builders. He did say that if he had done all the work himseld, he would have got it under $30K. To give you an idea, all the other case studies on my website www.buildahottub.com (and on this channel) and most of my builds with customers come in comfortably under $10K. Cheapest you can do it for is about $6.5K. - Hope that helps and thanks for the comment. Cheers, Andi
I would love to see more of the forming process, I feel as that was skipped over! great build

Amazing video super useful, loving those curved contours, exactly what we want in our new hot tub!
im living apartment in seoul now and so jealus about how large living place american has.

What a great comment - thank you!
what was his total time and total cost for his build?
Hi Diego, this was a 30K project for the customer in the end as he had a lot of the work done for him by contractors - took about 3 months start to finish. Most customers build well under $10K to give you a ball park figure - this was a complicated setup with a lot of kit. Hope that helps - Andi
Now for the question many probably have: How much does it cost to build a tub like that?
Hi There, this build Kyle used a lot of contractors and ended up costing just under $50K. This was half what he was being quoted by several pro pool builders. He did say that if he had done all the work himseld, he would have got it under $30K.
