Contractor cut electrical wires under concrete near pool
I hired a company to come to my home and lift some concrete that had sunken near the pool. The results of the concrete lift looks great, no problem there.
The problem is when they were prepping the section to be lifted, they used a big concrete wet saw with a 14" blade to cut down the control joints of the concrete, to make sure it wasn't attached to the sections bordering it (they also bore/drilled down into the concrete, at least 8 to 10 holes, approx 6" deep). There were only two control joints cut, both running across the concrete, from the pool edge to the grass. In cutting this seam, they cut, or at least nicked, the wires to my underwater pool light and /or the deck light posts (4) in at least one of the saw cuts. Not sure which light wire is cut, probably both, as now the breaker that both lights are connected to trips when you try to turn it on. If you look down into one of the concrete cuts, you can see copper in the wire where it was nicked. I have not examined the other cut yet as it was getting dark. And they filled in the drilled holes with patch, so I can't even look into those.
So, whose responsibility is this to fix? I don't know anything about lifting concrete, or electricity for that matter. I know if you personally dig you are supposed to call 811. But this trenching & drilling was done with mechanical tools, on my private property, by a contractor. He never told me I should get possible lines marked. He saw there was a light in the pool, and I would think he saw the 4 pool deck lamppost lights that are on edge of concrete. I live in GA. I have tried to find the answer online, but have had no luck. Any help is greatly appreciated! If you need any clarification, please let me know.
