I am going to build a pool in the next few months, but before i get too far with my design i would like to ask some questions about recommended structural technique.
I am situated in Indonesia and right on the equator. The pool will be built about 25 feet from the hightide line. It will hopefully extend to about 2 feet below the hightide line giving a total depth in the pool of about 6 feet. The pool will be an infinity pool all being well with the seaward face being the infinity side. Size wise, i think about 40 feet by 20 feet will be the approximate size.
As im on an island, my only option is to mix the concrete ourselves and use plywood forms.
Im looking for help with recommended concrete ratios, thickness and rebar size / amounts. My substrate is rock / clay. Later on i'll be asking about everything else!
