Hey guys, I have a few questions about raised ponds. I am mostly a hard-scaper, but I do the occasional pond. I got a request today for a raised pond/ fountain, in a segmented retaining wall circle. The fountain is a large, 1,000 pound, brass basin that his held up by a a few brass angels. The job is a lot more ostentatious than most of my normal work, but the customer is adamant. Here is a basic sketch (I haven't hat time to do a formal CAD drawing): Here is my game plan: 1. pour a concrete footer for the fountain, using sonotube and raised to the finished height of the pond. 2. Place geotex, followed by a pond membrane, over the footer. 3. Place the fountain on top of the membrane on the footer. 4. Build a 10 ft. diameter pond, around the fountain, held in by segmented wall block. What is the best way to secure the rubber to the block? I don't want any of the rubber showing, should I be considering an alternative to the rubber? Maybe something more formal. Any feedback would be greatly appreciated.
