Question about sealing a concrete pool deck

Earlier this year I installed a fence around my pool (former homeowners didn't ever install one but I have young kids).

It's a normal aluminum fence, nothing special. I couldn't embed the posts in the ground outside the deck due to not knowing the locations of plumbing and electric lines, so I used flush mounts instead. Each flush mount is anchored to the pool deck with (4) 2-1/4" x 1/4" concrete anchors in 304 stainless steel. I used a hammer drill to make the holes.

It just occurred to me that I never filled in the holes with any kind of caulk or epoxy, and winter will be here before I blink. Obviously the anchors are pretty tight but they're nowhere near watertight -- if it freezes and there's water in or around the holes, would that lead to cracked concrete?

Is this something I need to go back and correct? It would be a gigantic pain in the butt, but if it prevents a cracked/broken deck...

The brass anchors for my pool cover don't appear to be caulked or epoxied and thankfully those haven't cracked.

Also, I have noticed one or two small hairline cracks on the deck (not near any holes that were drilled). Should I go ahead and seal these?


Thanks for any advice. :D

Personally, I do not believe that little amount of water will expand 3,000 PSI or greater concrete and crack it. From what I have been told, concrete will start with stress cracks due to shifting of soil and possibly a lot of moisture that is trapped in the inner bottom surface.

I would highly recommend registering for a concrete section of a forum as they will have better insight if you do not get any answers on this forum in the next couple of days.
