How to fix these chips?

[karicali]

Hi pool nerds! This chunk (in my hand) came out of my grout, and that made me notice the larger chunk above it that is out. Without redoing our whole pool, what product(s) should I use to patch these spots? This is a fairly isolated issue, so I'm thinking patching would be fine? I am only a second year pool owner and inherited this pool and its issues. This IS the corner with the steps (which are weirdly tiny in an otherwise big, beautiful pool?).

Thanks!

More grout. But you’ll probably be patching it again in the future because of the lack of expansion joint.

I think the cracking and chips are from winter freeze/thaw cycles and not a lack of an expansion joint. Water gets into cracks in the stone or mortar, freezes, and expands.

That is mortar, not grout.

Best you can do is chisel out loose mortar and fill the voids with some Type S Mortar.

So I can get a bag of this mortar like from home depot, not the pool patch brand I was gonna get from amazon? Thanks for the feedback!!

Yup, chip out the loose mortar and trowel in new mortar.

Kinda looks like the deck was a renovation to add stone coping and they just mortared/grouted the face above the tile and below the coping stone. There’s a horizontal crack running left in picture right above the tile where that chunk came from.
