A couple pieces of tile fell off my pool wall near the steps. I'd seen that the grout needed some repair but forgot to do it. When the pieces fell off I noticed a big crack behind the tiles!
So my question is, do I look up (or get a book on) grout/tile repair and go about repairing the tile or is it likely that I've got a MAJOR problem with the crack there and need to get a pro in.
The crack (at least the visible part) is above the normal water line.
