I’m thinking of using Great Stuff Pond and Stone polyurethane spray foam as a cement mixed in with aragonite gravel in order to make an aqua scape. I can’t find anything comparable in search.
Great Stuff notes on the bottle that their foam isn’t designed for structural purposes, but I know polyurethane is sometimes used in light weight concrete applications. Anyone ever try this?
