You have noticed here in the Philippines if you use wide tiles – they always bend over time – and when they bend – they detach from the floor causing accidents and other problems.
Wide tiles like the 60cm tiles easily bend over time because it’s wider surface area means there are more chances of the steps landing on the center of the wide tile, and over time this causes the wide tile to hollow down on the center especially when most contractors usually use a masonry type of cement and / or the common tile adhesive to stick the tile to the floor.
We suggest you just avoid the wide tile and instead use smaller tiles like the 40cm or the 30cm, and always use the Portland cement to stick the tiles since Portland cement is for structural tough purposes. We have noticed even the standard tile adhesive is weaker than Portland cement.
The smaller tiles always allow the steps to land not just on one tile’s center, but there are more chances of the steps landing on two tiles which means the weight is usually always carried by not just one tile.
