What if I used those long skinny balloons glued together in an interesting shape to form out the walls of an under ground hide? I could use concrete or GS to cover the balloons and pop the balloons when done. Would it be necessary to seal either the concrete or the foam? If so with what? Silicone, or drylok, or epoxy is off gassing an issue with any of these. I thought I read that once fully cured (30 days) concrete was PH neutral. What do ya`ll say I`m brainstorming here. Any thoughts?
