Cracks in the floor of your building can indicate much more serious structural problems in the building. In fact, most people who live in apartment buildings in California and see cracks in the floor after an earthquake are likely to pack up and leave, rather than risk falling through the floor when the cracks finally meet and break. Do not allow cracks in the floor to send you out the door. When you repair the cracks in the floors of your building, you avoid all of the following issues.
As previously mentioned, cracks in the floors of a multi-story building eventually result in floors collapsing and leaving immense holes. If you do not believe that, you should see photos of old, abandoned asylums and the holes in the floors and ceilings of these placings. Along with collapsing floors, you end up with broken pipes, which makes things even worse.
When floors crack, they begin dropping and resting on top of any pipes that are running under or through the floors/ceilings. (Remember, one person's floor is another person's ceiling in a multi-story building.) As more and more material slowly drops on top of these pipes, pressure is applied until the pipes break. When the pipes break, then you get water damage. Now you not only have to fix the cracks and holes in the floor/ceiling, but you also have to fix the pipes and call for water damage and restoration contractors.
When the Floors Are Wood or Concrete, the Problem Is Really Bad
So, when the floors are concrete, the cracks happen faster, and floor cracks become holes and potholes. The concrete, with its intense weight, causes floors/ceilings to fall faster. The heavier weight does even more damage to pipes. What a mess.
If the floors are wood (as they are in really old buildings), then the wood rots. The cracks in the wood are the result of dry rot, or of wet rot that has repeatedly dried up and has been rewetted. Finally, the boards only need the weight of one average adult, and BOOM! the human falls through the rotten wood. If any pipes are busted in the fall, the water lands on the next floor/ceiling and begins this process anew, rotting yet another floor on another level below. Fix the cracks in either kind of floor as soon as you can, and all of the above can be prevented.
