I have a 1958 concrete pool that is 30x60x13' deep. It is fantastic. I bought the place last year. This past winter, the concrete was damaged where there must have been some cracks where water got in and expanded. As a result I have pieces of concrete coming off. The pieces are approximately 1" deep x 12" wide in odd shapes.
I want to get ahead of it. Least year, we used "quick Crete" but that didn't work. Any suggestions?
