I have a pool under construction. They shot the shotcrete 9 days ago. We had several days of heavy rain since, but dry for the past 4 days. I have an area outside the pool where I'm seeing water collect. I have a call into my contractor to come out and take a look. He said it probably was water just seeping up ... being pushed up by the pool. I have read this elsewhere on the internet as well, but I'm concerned that we might have a leak in the pipes. He had me look at a pressure gauge that is connected and it does show 35 (psi ... I think). Should I be concerned at all?
