Tile glued directly to my basement floor!

We recently bought our house in November of last year (2011) and noticed that our basement floor grout wasn't sealed :(. Progressively we began to check things out before we went on taking care of the situation beings the whole house wasn't taken care of very well. After a short while of owning the home the tiles began to break as weight was put on them :eek:. We found out the person who laid the tile had no experience with tile and it was glued directly to the concrete and very unevenly! There is still lots of good tile, but lots of cracked tile. They are 6in tile. We want to tear all of it up and would like to try and save all the tile possible to use in another room if we can! Can we save any of it? How do we get it out? What do we do? I am guessing it is probably a lost cause to try and take it out. But wondered also if we could do something on top of it? Would that be the better answer? Just cover it up with something better?

The bad news;

If they are cracking then you have movement, which is bad for tiles. It all has to get taken away.

The really good news:

Since they used mastic to install the tiles you can simply pry up the old tiles and wash them off with a power washer. If they won't pry up, then try soaking them in water to soften the mastic. It may take overnight but when wetted, mastic turns to goo again, which is why no decent Pro will use mastic for flooring.

They crack when we step on them. When there is weight put on them. Mastic must be the only way you can glue tile to concrete floor? Thanks for your reply!

The correct way to have installed the tiles is with thinset, which is a cement based product and 'cures' to be as hard as .. well... cement. Since they break when stepped on, the mastic underneath is still as nice and soft as the day it was applied. Get to scr aping.

Looks like we are just going to have to cover it up. glue is rock solid and it would be a major headache to try and pull all of it up!
