Re: Repairing busted grout
I'd look at an self leveling elastomeric sealant rather than grout. Sika is a good brand of elastomeric and is sold in caulk tubes. It comes in tan, grey and red. You need to put a foam rubber "backer rod" in the joint before you seal it so it doesn't take fourtyleven tubes of sealant. The elastomeric will move with the shifting and settling. I don't know of any reason this shouldn't be done around a pool, but if someone can give you a good reason, listen and decide for your self.
Good luck!

Re: Repairing busted grout
Home Depot had the Sika product for $12.99 for a 26 oz tube. I'll check WalMart, too.
I think what was originally used was a similar product. It looks like mortar but it's rubbery instead of hard and brittle.
I'll go with your suggestion.
Thanks for the tip.

Re: Repairing busted grout
If you did use a grout product, apply it with a piping bag. Its a cone shape with a small opening at the tip of the cone. Fill it with grout and squeeze. Bakers use the same kind of thing for cake decorating. They can be gotten at Lowes.
