if replace old floor tiles by hacking does it damage the water proofing ?

Waterproofing is not forever.

If waterproofing is more than 5 years old, and yr new tile is suppose to last u another 5 years, then u run the risk of waterproofing failure within the lifespan of yr new tile.

My view is that the savings is not worth it to overlay wet areas.
