Expansion grout material

I hope I’m posting in the right spot, and bear with me, I may have posted this inquiry before ( maybe even with pictures).
I have an inground pool that was built 24 years ago, and the grout / material used in the expansion joint on the decking around the pool ( originally a grey pliable material) has now hardened and is breaking out in chunks.
It needs to be removed and replaced.
Could anyone suggest a replacement material (type, brand, application suggestions)
Thanks in advance,

Deck-o-seal or Sikaflex (available at Home Depot).
