Dangers Of Hollow Tiles

[hposnm 0]

In the midst of checking on the laying of the masonary work at my place now. The acid wash has already been completed. I've found quite a number of hollow sounding tiles. However, I'm unsure if I ought to replace them because:

a) Some of them are located near a "hollow" area (e.g., rubbish chute).

b) Some of them are located right in the middle of the house so the replaced tile will most certainly be super obvious, not to mention, uneven!

c) Some of them (wall tiles) are located near an area which had previously been drilled (e.g., double power socket points). I checked some of the tiles near the other powerpoints but did not have similar problems of hollowness.

I would like to ask if there is any safety danger of having hollow tiles on living room floors (Approx 1 full pc) and kitchen floor (3 areas, not whole piece is hollow) and kitchen walls (Approx 3 full pcs).

If there is no real danger of tiles popping or cracking or falling off, then I might just get the contractor to give me a discount on the bad workmanship rather than to get him to re-do the tiles and delay my move.

Can anyone offer any advise on this?

Thanks for this. I'll have them replaced then. Appreciate your comments.

Has anyone encountered a situation where a whole row or section of your tiling work is hollow near the rubbish chute? Esp those located in old (30yr old) HDB estates? My bro thinks the area where a whole row of hollow tiles was discovered might just have been an unreinforced concrete section.
