New Pool Owner Concrete Repair Question

[quinnsta]

Op Please feel free to move this post if it's in the wrong place.

We just bought a new house with an in ground pool. All around the pool there is a gap in the concrete between the white edge that holds in the liner and the concrete. I have attached a picture below. This is about the widest gap, some areas are more narrow.

Need idea's on how to repair this, and what materials to use. Some portions are narrow enough for a concrete filler others look like the need concrete.

Any advice would be much appreciated.

Thank You.

I have been reading a bit more into this. It looks like many recommend Vulkem Caulk with backer rod for these joints. Does this sound right?

That gap looks too wide for caulk. How wide at the widest? Narowest? Average?

even with backer?

I can't believe the walls/concrete have moved so much! I do decorative concrete work and I'm not sure backer rod would close up the gap between the wall and the concrete.

I believe at the widest point its just over an inch. That's the worst spot. I think they cut some out to replace the liner. I may need to concrete in the larger spaces.

That's too big for caulk. They make some patching masonry products without sand that will give you a nice finish and dry very quickly. HD and Lowe's have it.

It WILL be a starkly different color and it WILL crack some and it WILL NOT bond completely to the old concrete. YOu may want to consider painting it when you are done.
