crumbling grout and hollow coping

Hi - I have a simular problem - what did you end up doing?

[PoolDoc]

Most of the posters and all the moderators here are residential pool owners, not pool builders. Even most of the pool guys here are service guys (like me), not builders.

So, when you ask a builder question, here you may or may not get an answer.

You can try at poolspaforum.com -- there are a LOT of pool guys there. The problem for me is, if I let them in here, it seems most (more than 90%) can't tell the difference between "helping" and "selling" . . . and most of them want to answer chemical questions, even though much of what they 'know' about pool chemistry is wrong.
