One reason grout between tiles cracks is that grout over time will dry out
There are several reasons grout can crack and almost always has to do with movement.
1. Gaps are too big - joints that are over 1/8" thick should not use standard grout its simply not designed for joints that big, use sanded grout for anything above 1/8"
2.Weak or flexible surface - If the surface your walking on has any flexibility or weakness it it will cause cracks in the grout as the surface underneath flexes or moves. e.g. Plywood
These two are the most common reasons for cracking, severe temperature changes improper filling of joints or thin mortar can also cause cracking but are more uncommon.
If you hear crunching sounds under the tile the mortar is most likely cracking and your tiles will be soon to follow.
If a force is strong enough, it will crack the tile. Fast movement of the earth might cause tile to crack also.
Probably, it depends on how thick the tiles are. But after awhile they will crack from the weight put on it.
Crack.
I have heard that metal tiles are the best for supporting heavy weights. I would recommend metal tiles over ceramic, as the ceramic tiles would probably crack easily.
Crack all the ice tiles :3
Disadvantages : the floor tiles might crack . the wire might snap . :)
if its not a safety hazard, you can leave it, but if it bothers you, it can be replaced if you still have some extra tiles
Spreads the weight over a larger area so you dont crack or break the roofing tiles, they are made of clay & break easily
Sandstone tiles will last for many years if cared for properly. Dropping heavy objects on them can cause them to crack. You will also want to use a sealer on them because they are porous and will stain.

15'x15' is 225 square feet; so I would figure on 225 tiles. I would get a few extras in case some crack.
Earth has seven tiles and when they wobble or move they make earthquakes, where there are joints of tiles they make earthquakes e.g. Japan. Japan is on the ends of two tiles and it also has volcanos so its easier to have volcanic eruptions so when they wobble or move they crack the lasnd and also make earthquakes happen
Generally speaking, you get what you pay for. Cheaper tiles would likely break and crack more easily, due to cheaper materials in their making. More expensive tiles may be of higher quality, but also deserve a but of research before making an investment.
