Hi guys, my house is newly renovated about three years, from around two years ago, i noticed that my tiles will have loud popping sound at night, my guess is because i turn on aircon at night, causing contraction of the tile. Is this because of poor workmanship? This has affected my sleep as sometimes in the middle of the night it will pop sharply, and it goes on for a few seconds. Will the tiles come loose in future?

Didn't know tiles need to be soaked. Hope it will last few more years before i need to replace it.
