Adding on to pool area slab


I'm in the process of remodeling a mid 80's home in Costa Rica and need some advice. Around the pool area were some ugly ceramic and concrete benches. I removed them and as you can see there is nothing but dirt underneath. I want to pour concrete in these areas. I have a few questions.

1. How should these new areas be sloped?
2. What type of drainage should be incorporated?
3. Should the rebar for the new slabs be tied into the concrete next to the pool or the house footer or both?

you'll need some isolation jnt material & a diamond saw to square up the existing conc,,, just pitch the new conc so rain doesn't enter the pool,,, if it were mind, i wouldn't be using any tie bars because the pool & house are structures,,, ixnay on tying into them.

Thanks itsreallyconc for the input. How many drains would be sufficient and what size pipe? Aside from the factor its in close proximity to the pool here in Costa Rica the rain can be intense. I want to move as much water as I can quickly away from the pool and house. Also at a later date I intend to put a decorative concrete overlay over the new slab and over the old tile around the pool. Would that change the scheme of things?

from your pics, you don 't need any drains that i can see so let the ALMIGHTY drain it for you just place your conc so there's a slope & wtr will run downhill [ trust me on this ! ]

dec conc o'lays can range in thickness from 1/16" ( troweled ) up to 5/16" ( thin stamped ) so plan your elevations accordingly.

How should electrical bonding be done with new concrete to existing pool bonding?

Bonding of the rebar used in the new concrete to that of the rebar and associated metal of the pool (ladders, pump, lights,...) already bonded.

we wouldn't use reinforcement in the new concrete since it appears to be only 4" thick HOWEVER that does raise a good point - should there be a ground ? i don't know but will ask & report back.
