How to back fill a preformed pond in a frame on patio flags
Thank u mate just how I was thinkingOn top of what @Stephen Noble said, I would think you needed to backfill as you built the frame. Not sure how you can do it now without partially deconstructing.
Maybe pull the preformed pond and backfill until you have the liner resting flat on the sand like @addy1 said. Be sure to compact thoroughly so it doesn't settle. Then pop the top boards off that the edge of pond is resting on and backfill around sides. When you get to the top, slip the top boards back in under the lip of the pond and secure them.
though Stephen, shouldn't the preform expansion be almost nil? Sand is pretty forgiving and I doubt he can fill 100% nor should he, imo.What are the sides of your framework constructed from? Can they withstand the pressure? The weight of the water plus sand could cause the sides to bulge out if there is not strong framework.
