Customer wants to put Remanoid pond in his house and support it with a structure that would support the ledge all the way around but he cannot back-fill it. Would the pond be strong enough for this?
If he means to only support the rim and have nothing below it that will definitely not work. The walls of the preformed pond are about ¼” at the thickest which is at the top. The weight of the water would definitely make it collapse.
