Help or recommendations desperately needed!! I have tiles on my kitchen floor of which some have broken-long story. I decided I wanted to place lino on top of the tiles so I removed the loose broken tiles and cemented the hole left behind. I have since had lino fitted and today I have had to remove it as the tiles underneath were making a crunching noise. On examination there are now several tiles that are lifting when you walk over them and some cracks. Not sure what to do? Where to start? Do the tiles need to be removed completely or can they be covered somehow? Any recommendations greatly appreciated.
