[quote:ZEROeffect:MV8yMTU3MzY0XzM2NDY0ODgxXzJDMzJFQkY1] [quote:DanT:MV8yMTU3MzY0XzM2NDY0NzM1X0MzRjdCMTFB] [quote:Anonymous Coward 35473189:MV8yMTU3MzY0XzM2NDY0NjY4X0MxRjM1M0Q1] I'm a concrete finisher. Concrete is very strong and can span large distances unsupported. If that sinkhole opened up it most likely would have happened quite a while ago and over time caused the concrete to crack. Keep in mind that there is a foundation as well that supports the concrete. Also the hole looks square. Concrete does not break in a perfect square (unless there was perfect relief joints exactly where this mans bedroom was). Assuming the concrete was a typical 3 1/2 inches thick or possibly 4 inches thick it could support many many thousands of lbs before it finally gives way. This is suspicious to someone that understands concrete. [/quote] Notes: 1. Concrete is strong in compression, but not in tension 2. A house *does* weigh many thousands of pounds [/quote] Concrete used for a floor would have [b]rebar [/b]running throughout it. [b]rebar [/b]that runs the lengths of the house. one gets attached to the next every 12" or so. They run it in a grid like pattern. The concrete is mixed with rock as well. Depending on the mix.
