We've had torrential rain the past 24 hours. Excavation was Tuesday and Wednesday of this past week. Rebar was Thursday. They laid tarps in advance of an expected rain, but it likely didn't do much good. After 7-8 inches of rain last night and the gutter draining precariously near the pool, we woke up to a muddy and completely filled pool. They are draining the pool as I type so I'm not sure if the walls, steps, or benches caved in at all. Moving forward, what do I need to ask and look for to make sure that we have minimized any structural integrity? How dry will it have to be before it makes sense for them to plumb and spray gunite? Is there anything else I should ask our builder?
