I purchased home with pool 5 years ago. Not sure of builder or technically what finish. No big issues.
This year I "discovered" long cracks in areas of the "pebble" tech finish. The cracks range from 6 inches to 2 feet in length. And as wide as 1/4 inch. They are located on the steps in the shallow end. And on another another underwater shelf in the shallow end. No cracks on shelf in deep end.
I have read online about issues that might be caused by the builder using "rebound" to build up these areas.
Any idea of what I am looking at to fix these issues? Can you patch vs having to redo whole pool?
