Porcelain paving??

Hi. I'm currently laying a porcelain patio using 600x600 tiles. The sub base is down and compressed ( type 1) I have started laying tiles using 6:1 sharp sand to cement and an sbr/water/cement mix as a slurry to go on the back of the tiles. I've noticed that some of the tiles sound hollow when I tap them even though I made best efforts to bed the tiles using full contact. My question is if a tile or 2 pops which I'm guessing will happen over time is there an adhesive I could use to bed it back down on the mortar base? Also, advice other advice would be appreciated.
