Slabs have issues that need to be investigated as well, not all of  
them are poured as thick as others and just because it is on ground  
level does not mean that it has the ability to withstand a high load  
per square foot. Allot depends on the amount and type of rebar and  
the depth of the pour and type of concrete mix. Also some floors have  
things buried in them - like heating pipes and electrical pipes.  
Sometimes there can be an erosion of some of the soil under the floor  
which can lead to the floor becoming cantilevered without being  
designed that way - drainage can be an issue. Again - all good  
reasons to have an inspection by a knowledgeable person.
