Brick Dome




I was looking for another picture in my files and found this.

Brick dome used as rain water tank. Inside is plastered with waterproof cement. This one holds about 50,000 liters. It catches rain off the kiln and drying shed roofs. although a pure round dome is not good structurally this is back filled and so the pressure from above allows it to work.

I tried dome roofs for residential but they have too much reverberation and echo, and that is how i got into vaults.

Re: Brick Dome


Gotta love that access plank.

Why don't you get a 2 X 4 and stand it on edge so the workers have to concentrate on the way to the site.

I just love the dome and vaults, going to find a way to build one someday.

Always wondered why you guys are using forms for pizza ovens. I posted pizza oven made same way, but smaller.

Re: Brick Dome


I like the strings to hold the brick in place while the mortar sets.

Fundi, this is what I used. It is two pieces of rigid foam insulation cut so I can take it out when I closed up the dome.

This is around the time I started using the form.

I am guessing the firebrick over here is harder and heavier than the brick you are using for your dome. You can build a pizza oven dome without a form but it speeds things up because you dont need to hold the brick in place until it sets. Some people use a sand form but I dont because you can keep the brick nice and clean as you build...to each his own. I really like that wire idea!

Re: Brick Dome


stonecutter how long before you can move the foam?

the wire hooks are nice because you use on any sized dome. If you look carefully the "hook" have Y at the bottom and bent out for loading 3 bricks. Only on the top flatter part do they then use strings to get more tension. The 2x2 is the gauge and sometimes they have a bolt on that to hold the brick but that slows things down.

Hmm foam. You got me thinking as I am building a timbrel arch and foam might be best / cheapest for first row.

Plastic? Last time i checked 50,000 litres plastic was more expensive for me here.

We agree the genius is the technology. I imitate proven technology. The only innovation we did is the cutting of the groin pieces.

In my area I would guess there are 500 underground domes, most for making bio-gas so it is a bit ho-hum. Groined vault is another story.

I am glad if it tickles someone's imagination. It also tickles mine. I enjoy looking at interesting work, beautiful work, such as yours.

Fundi, I would say around 15-30 seconds. The foam would hold two bricks so I made faster progress instead of waiting for the mortar to grab. Not that I needed to go fast,this one was at my house..it was a case of impatience. I wanted to fire that oven up!

I am going to try the wire hold with the next dome for sure. I'm thinking if I make 5 wire holds that would be plenty...now its just a matter of finding time to build.
