Anyone knows what type of material is this that goes between the pavers and the tiles? Thank you

Hi @bonino,

I don't think it is what's there currently, but usually you would use a flexible sealant like this Sika Concrete Grey Sikaflex 11FC Purform as it will keep water out while still allowing some movement.

Let me know if you have any further questions.
