The closed high density foam, I’m hoping shouldn’t soak up and rot, maybe I’m wrong though?
We use this type of foam for gaskets at work. It does go brittle and age over time, it will not last indefinitely. It is not designed to stay wet so I have no idea how it will react over time under the dome taking hours and hours to try out. For this reason I just used a small amount around the outside that could be sealed from moisture ingress, if it does go off I do not have to lift the dome again. For my floor I will be using the carpet tiles from Bunnings, carpet helps reduce internal dampness and will wear a lot better.
