In fixing my pool skimmer plumbing I had to remove about a 12"x18" area of
my concrete pool deck. The deck is a 4" thick concrete slab, then a layer
of 3/4" tile on top.

While fixing the plumbing, I noticed an electrical conduit that went below
the slab, I believe one end of it goes to the exterior wall of the house
where there is a switch and an outlet, and the other end go to a planter
area twenty feet away where there is a conduit coming out with a few
outlets, used for exterior lighting. There are several planter areas around
the pool deck, all with electrical outlets coming out of the ground.

Problem is, the rigid conduit these wires are in, is badly corroded, the
area where I opened up near the skimmer, the conduit was corroded so badly
when I poked it with a stick it broke like a twig, exposing the red wire
inside. I suspect it's the same with all four wires that ran underground to
get power to the planter areas and may be the submerged pool light as well.

Something tells me it's not safe to have exposed hot wires like this
underground especially where it may be wet - near the pool plumbing, in the
planter areas where it could get water from the sprinklers, but it's not
practical to rip up my entire concrete pool deck just to redo it.

Is there a practical solution?

Thanks,
