Ultracolor Plus is a highly flexible grout.Scottey, better late than never!
The void is about 60-70cm off the ground only. What is considered adequate?
TJ - there are no cracks in the tiles. In many places, the grout has cracked or seem to be stuck to one side only. I DON'T ' think the grout (Mapei utracolor plus) was a flexible one so this is expected given flexing in the floor. In some area its whole groups of tiles together - in others 120-180cms width.
Looking at some pictures, it seems to me the tiles that have lifted the most have been where two sheets of plys meet. It seems to affect the whole row of tile. Tiles adjacent to these are less affected.
Thanks
