The dome I was working on last fall was done with porous forms. I had stucco mesh on one side, and plywood on the other. Using a wet mix, I filled the forms with a bucket because my pump was out of commission.
As far as I can tell there are no voids at all and I ended up with very solid 14" thick walls. There is no seam between layers. After removing the plywood in a few hours, the walls got hard in a couple of days, and I was able to peel off the mesh, leaving just papercrete. Now that spring is here and the windy season should be just about over, I'll get back to pouring.

I think the chance of voids in the papercrete will be less that way . . .Mikey? Based on your battery room experience, which would you recommend?ElfN
