Good morning.

I'm looking at an existing pool that has had the surround concrete demolished, and will be replaced with travertine tiles on tamped gravel and sand. I found two small pieces of rebar poking out of the center of the shallow end wall, and there is a hydraulic cover operator at the deep end.

What should be done for bonding? I know about needing the mesh under the travertine, as well as any metal such as ladders, and a water bond. The main question is whether I would need to expose existing rebar to connect to like one would for an Ufer ground in an existing footing.

What should be done if I can not find rebar to expose? What might I be missing or forgetting to ask about?

What the pool looks like now, a piece of rebar poking out, and a side wall with no rebar exposed:

No vinyl. It appears to be painted concrete or parged cinder blocks. I don't know if it was sprayed on.
Don't know how the rebar is laid, but at the least I would tie your mesh grid to the exposed rebar. Also to the rest required for the EB. Don't forget the water.
 
I would probe for additional rebar on the 2 long sides and the opposite end to establish the 4 points Are you required to put down mesh? Or does the AHJ allow the single, bare #8? Some states still require the copper mesh.
The motor for the auto cover must also be bonded.

The bonding at "four points" for an existing pool is part of the info I'm looking for.

We're still on the '17 NEC. I'm going to check with their county's building department.

The motor and pump for the cover are about 25' away, and drives a hydraulic motor.
