My gunite shell was poured last week on a day it was raining. They did cover it with a tarp at the end, but it ended up caving in due to the water. I have posted some pics of the result. It also appears that the slope of the pool does not go down evenly on both sides. One has a much more pronounced dropoff. As I know nothing about gunite, it this easily repairable? Can they "regrade" the pool to make the slope even? Any advice much appreciated. Thanks
