Hello, my less than 1 year old pool has cracked/leaking returns. The pool is surrounded by about 6ft of concrete decking. When the diagnosis was done the thought was that it is inside the gunite or under the pool deck as there has been no visible water. Does anyone have experience on how this can/should be fixed. Since the pool is brand new preserving the ascetics is of real value to us ie I don't want to plaster or the pool deck to look patched.
