Catalan Vaults


youtube of a fella bricking up a vaulted ceiling/roof. Captioned in English. Explains how such soupy mortar can stick a brick overhead so well.

Im always fascinated when I've seen these guys at work.

Re: Catalan Vaults


I love watching that as well

All that I could find out is that they use some sort of fast setting mortar but I could never find out exactly what the mix is or whatís in it

Obviously you need to use the right type of bricks and mortar in order for that to work

he mason in the video, Hugo Martinez, uses mortar made from cement, lime, and sand in a 1:1:8 ratio. As you can see, it is a loose mix but the brick is dry so it absorbs enough moisture to cause it to grab. When used as a roof, the top of the vault is overlaid with rebar and a layer of mortar or concrete.

Yea I have seen that article and the mortar is nothing special, I see that the mix is soupy as hell though. I know that if you try doing that with a hard brick it wonít work. The Only super soft brick that I know of that absorbs like that is a common brick and I donít know if that would work because I never tried it.... haha

Re: Catalan Vaults


Amazing, the brick must be like a sponge, suck the water in and bond up, guy makes it look easy, I bet it's a lot harder to do than it looks like.
