Hello every one.
First of all, thank you for this great forum, I found plenty of infos, advices, and ideas from the threads. A DIY pool looks very doable from what I have seen, but I still have doubts about a few things.
I plan to build a (very) small concrete pool, 4m long, 2m large, 1,2m deep, with an infinity edge on one 2m size wall. The water will flow in a 1 cubic meter surge tank, looking like "faranginkorat" did, which can be seen in this topic: http://www.coolthaihouse.com/forum/viewtopic.php?f=19&t=5077. It looks nice, and easy to build. One bottom center main drain, one water eyeball inlet opposite to the overflow edge, tiles for finishing, and sandwash for the deck.
I want to keep it simple and cheap, but strong and durable, without to much maintenance in the future. Budget, more or less 100k THB, hopefully.
Now, my questions:
- 15cm concrete floor and wall ,with one 12mm layer rebar. Is that enough ? Too much ? Or 20cm concrete ? Or two layer rebar ? Does the concrete need waterproofing, or only the render ? Possible to go without vibrating the concrete ?
- For the formwork, I don't want to rent steel, or to buy wood, so I think about a double blockwork. Is that fine or not ?
- The land is an old rice field with 1m top up soil. The bottom of the pool will be almost at the rice level. First rice field is 10m from my pool location. Do I need an hydrostatic valve ? Or a drainage pit ? Or both ?
- For the pump and filter, I found this: Emaux FSF350-SS 14" 0.33HP pump+filter combo, with zelbrite. Is that ok for this size pool ? Is Emaux reliable ?
- Is the surge tank big enough ? 1m3 for a 10m3 pool ? It is 10% as I have seen adviced, but because of the small pool size, the tank is pretty small.
- I want to go for a salt chlorinator, but I am a bit clueless about it. The smaller unit fit for about 40m3 pool, which is way bigger than mine. does it matter ? Is there smaller unit ? Any big difference between Zodiac TRi compact, and Emaux SSC15 except the price? There is also the Emaux SSC15 without timer. Do I need the timer ? (It might be obvious, but not yet to me !)
- About the tiles, can a local worker (working with traditional house tiles) provided with the right adhesive do the job, or does it take special knowledge ? Is it possible and worth to hire workers from the tiles compagny ?
That is all for now ! I am still planning, so I could use any suggestion or advice in case there is anything wrong.
Thank's a lot for your time and reply.
I can keep this post going on with pictures during the building if some are interested.
Regards, Pierre.
