Pour in place of a vertical wall section
A portion of my building will have a retaining wall, and to insulate it, I'd like to simply attach the formwork I would already have and pour a section of AC right next to it and use it as thermal insulation. It will be roughly 8 ft tall by 8 inches thick by 60 ft long.
Should I do this in "lifts" so that the AC does not compress too much and the bubbles do not dissipate? I was thinking of pouring 6 or so inches of height at a time, waiting for a couple of hours, then do the next section and so on. Would that work?
You can pour several feet high with a good foaming agent. We just tried Drexel Foam concentrate and it worked fabulous. You might go the full eight feet?
