We are keen to turn this former plant bed into a pond but we’re scratching our heads as to how we attach the lining.

Do we need another internal wall structure to hold the lining or is there another way we could do it? Have looked at a few websites but they all suggest this. Or could we attach lining to top and somehow put another layer of stone to hold it in place?

Any thoughts? Also, before anyone starts, we are getting rid of the horrific Astro turf in autumn! It came with the house. We didn’t install it lol
