Hello and thanks for the insight. That’s not great news but I understand where you’re coming through. The owner is being somewhat casual about the situation but hasn’t been out to look at it. I sent a couple more pictures this morning and told him that what I’ve learned is that the rebar is rusting and this is a catastrophe happening. From what I’ve read online there isn’t an easy fix. The spa is going to have to be redone. Do you think it’s possible the piping for the spa jets could be leaking inside the concrete? This morning there’s rust running out from the bottom of the spa across the patio. I’m very dismayed.
