My condo has recently experiencing some pop up tiles around the house. One of it is even cracked. Any sifu can tunjuk jalan what should I do? Preferably an economical way 😃..

Should I just replace the tiles of the affected area? Or replace for whole house? Or change to laminate flooring? Or vinyl flooring?

Many thanks in advance

The economical way is to carefully hack the crack/pop up ones and replace them.

This is very risky and required very professional and skillful workmanship and luck too..

If luck not good, the hacking will create a chain reaction crack, which affects all the surrounding tiles..
It is better for you to just leave it there since it is not causing any harm to your legs, don't they?

Replacing tiles can be very dusty and mostly need to replace a whole section of an area. If too big area you can do a design like put a line of same color tiles to separator area A and B, this way you do not need to break all. My old house living room and dining were using same design tiles but we just changed the living and put another color tiles to separate living an dining just like how other people did the separation between living and bedroom.

How to be economical to replace the tiles for the whole house? Even if your house in Shire will still cost a lot! 🤣
Best is to leave it unless it is dangerous to let it be. Then next is to repair but like the other reply said you need a good repair guy and can get same tile(s).

Depends.

Cracked tiles should be replaced ASAP due to injury risk.

Laminate flooring, it is an economical fix especially if you have a lot of furniture and fixtures that are difficult to move or store. However some types may not be suitable for your lifestyle.

Redoing the tiles for the entire place, kind of like using a sledgehammer to crack a nut but if it is time to redo then its time to redo. Its a messy process though.

Changing affected sections is an option. Can be done especially if you are not particular that the colour of the tile would be different to the old ones. There will be some dust but there are ways to minimize it.
First off, it will need a contractor or tradesman that would take instructions. The steps are fairly simple, contractor to use a saw or angle grinder with either a dust collection or have someone with a powerful vacuum cleaner follow the blade. Cut out the sections of the tiles that need replacing, then slowly hack off till 2-3 inches deep, then replace the tile. Not the quickest but can be done even if it is a 3x3 tile.

You will need to knock knock the tile everywhere.

How many empty sounding tile there is?
Those are the tiles with risk of popping up in the future.

Then you can make your decision.

If only a few just do those few enough.
Even easier if they have pop up already.
Just need to remove the layer of cement below and some from the tile.
Then use correct technique and tile adhesive to lay back the tile.

This happened to my house before. First, we broke those popped tiles and cemented it, then laid laminate flooring for the whole living and dining area thinking that maybe we solved the problem, but a few years later and huge row of tiles popped from the living all the way to the dining area (popped under the laminate flooring). We thought maybe just remove the laminate flooring and remove the row that popped but when the workers started removing the popped tiles, the tiles from the other areas started to pop aswell, so we removed all the tiles, screeded the floor and installed back the laminate flooring.
