Got the 4 boards at the bottom done. I’ll be adding 1.5” foam between the 2x4 and then a layer of 1/2” foam over everything. Overkill but can’t be too safe plus will help with insulation.
pond liner is here and it’s massive. Certainly going to be difficult to move around and install.
For the top bracing i’m thinking of going with trex braces 2-3 across the top evenly. I’m eventually going to do the complete rim in trex and i can splice around these and make them look perfect.
think trext is strong enough for a center brace or would you recommend something else?
