Update: root cellar with vaulted ceiling

Are the gaps between the bricks there for a reason? I would have thought the support for the arch would have come from them touching more then just the mortar.

Oh yeah good question! That's not staying like that. According to the building theory books I read a jointing in an arch can be anywhere between 5mm and 10mm of mortar inside (1/4' to 1/2') and up to 25mm outside (1 inch)

The empty space will be filled completely with mortar next week. It was a huge mess when laying the bricks vertically against the wooden formwork, we noticed how ugly it looked when moving it off after laying the two first slices.

The plan is to use some kind of piping bag and inject the mortar precisely in the gap, then smooth it uniformly. There are different shapes, we haven't decided yet which one we will use:

We ordered this device to inject the mortar:

and some powdered iron oxide to give a darker tone to the mortar, we like it better with the color of the bricks. When all this arrives, we can continue
