Hi folks, we have what I guess is a serious problem with our 8m x 4m rectangular pool. There are several problems : 1. The pool seems to have a definite 'lean' from right to left, dropping by about 6 inches max. 2. The tiling around the pool has a lip. Directly below this lip the concrete is deteriorating and the tiles are falling away. 3. The back of the pool is a 3 foot wall. There are rectangular marks on this wall which seems to indicate a leak ? The pool is about 10 years old; I'm not sure if its a concrete or shell type pool. The tiling is typically spanish style 2 inch square tiles. Frankly I don't know anything about pool repair and I was hoping some good folk here might offer some advice on what steps to take to repair everything. Do I need to have the whole thing ripped out and replaced ? The lean seems to indicate ground subsidence ?
