Good morning dear forum
This is my first post here, and before I ask my question, I want to introduce my pool background very briefly.
I am quite a pool newbie, without hands-on experience. What I know in the field comes from the (in the meantime quite intense ) studying the information available on the net.
At the same time, Im very aware that it is super important to network with people who have practical experience, and that is why I am writing today to you.
Currently I am working on a house-building project in the tropics. Part of this will be an outdoor pool integrated in the terrace.
The house is situated in the dunes, the building ground is sandy. The house is built in the "Raft" method, which means a reinforced concrete column grid structure is additionally supported by a rubble foundation.
The terrace (which is level with the rest of the house floor) is 46 elevated from the ground. There is no basement, the base is filled with compressed red gravel.
The pool is integrated in the terrace. For better understanding, here is an excerpt from the plan:
The pool dimensions (inside) are as follows:
Total amount of water 12k Gallons
Salt Water Clorinator (Hayward Aqua-rite 25)
Pump: Pentair 011513 WhisperFlo 1HP
Filter: 3 Pentair Clean and Clear Plus Cartridge CCP320
2 inch tubes throughout
No heating (tropical)
Overflow over entire long side, with drainage channel, pre-filter
2 Ground outflows
Pool technology installed next to pool, also within terrace
Inflow on the short side of pool (close to pool tech), with 2 inlets
Due to various constraints (available materials, local knowledge etc) Im limited to constructing the pool using poured (in-cast) concrete.
So far, I plan to proceed like this:
a) Excavate required depth (1ft), compress the ground area (sand), and fill with about 1 ft of compressed red gravel
b) Make bottom plate with reinforced concrete, 6 thick
c) Create 3 of the side walls with reinforced concrete, 8 thick
d) Use the house side as a side wall (it leans against the compressed gravel, so statically, I dont expect complications)
e) Use plaster to even out everything, and create a smooth surface
f) Paint the walls with Epoxy (probably 2 coats), to limit erosion/ calcium diffusion
g) Use tiles for the floor
My questions to you:
1. Is a gravel bed required? Is additional foundation (e.g. rubble) required for the walls?
2. If so, is 1 ft of compressed gravel enough as foundation of the bottom plate?
3. Is the base plate dimensioned correctly? 6 ok?
4. Are the side walls dimensioned correctly? 8 ok
5. Any objections to use the house foundations as sidewall for the pool?
6. What type of plastering should I use to keep things waterproof, smooth, and not crumbling?
7. Do I need to use expansion joints for the concrete?
8. If yes, what is the best way to seal them?
9. Can I use normal Epoxy for painting?
10. Anything special to respect for the floor tiles?
Thanks so much for your answers, suggestions and inputs.
