How feasible would it be to convert a concrete rain water tank into plunge pool? We don't have much land to work with, and a circular rain water tank would fit in to the available space perfectly. Ideally I'd like to have the tank installed with about 50% of the side hight underground, with the rest painted, and inside tiled. Any ideas? Re: Would this be possible? 2Jan 17, 2010 5:17 pm Yes, you can use a rainwater tank as the 'formwork', just as you would for a standard pool only it would be round.

How feasible would it be to convert a concrete rain water tank into plunge pool? No...an above ground concrete tank is not designed for the earth plus saturated earth pressures imposed from the external side particularly when empty. Concrete above ground tanks are design for internal pressures acting outwards...and the reinforcement helps carry the resulting tensile hoop stresses. You can use it as a former (as Onc suggested)....but I doubt the economies stack up. And it you use a below ground water tank you might as well build a proper pool. mmm....donuts Homer Simpson 1956- Links: Site Costs Ready Reckoner | H1 Addiction Medical Advice | Château TDL: The Backyard Re: Would this be possible? 5Jan 18, 2010 5:26 pm Hi Guys, Thanks for your replies.. I've done a bit of searching and found a couple of pictures in an old magazine; seems it is possible to just use a topless concrete tank. Here's a few pictures I took with my phone, so sorry if they're not very clear: Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Re: Would this be possible? 6Jan 18, 2010 7:06 pm That looks nice.... and very new. ...but it might not look like that in a few years Well unless the constructor has used all manner of waterproofing. That looks about 50mm thick, the standard for water containment is 100mm. ...but of course there are things that will mitigate a long lasting product. lots of things to consider before just bashing one up.

Re: Would this be possible? 7Jan 18, 2010 7:12 pm That looks like it's completely above ground...not half buried which was the point I was making. A thin tank would have bugger all cover to the reinforcement...one small movement...one small crack and it's all over red rover. mmm....donuts Homer Simpson 1956- Links: Site Costs Ready Reckoner | H1 Addiction Medical Advice | Château TDL: The Backyard Re: Would this be possible? 8Jan 18, 2010 7:28 pm I was thinking nil cover as in nil reo tdl How about a thermal change like hot weather and the top above water level?
