hi
wanted to build an above ground pond out of 4 X2 timber and 18mm ply and then line it with a pond liner .its going to be between 12 - 16 ft long by between 6 - 8 ft wide and 4 ft deep.was planning on having the spacings between the uprights at approx 200mm with 4X4 corner posts with 4X2 length of total pond as top and bottoms in one piece.spacewill be insulated with celotex or polystyrene depends on final budget .outside will be clad with some form of cladding.filter will be pump fed with gravity return.
will be work okay please?didn`t want to go to exspense of concrete blocks etc as budget won`t be massive i`m afraid
cheers

Hi Giorgio

At 12 x 8 x 4ft the pond would hold 2,400 gallons of water , that water presure alone would in my mind cause the longest lenght of your pond to bow outwards.

If you were thinking of sinking 2ft of the pond below ground, you might be OK , but 4ft above ground using 4 x 2 timber will cause you problems. The only time I have seen a pond built using 4 x 2 timber, the ponder hired a steel banding unit to wrap 4 steel bands around the unit, then covered the whole thing with tongue and groove wood to finish it off. The steel bands gave the walls of the pond the added strengh that was needed.
