Apology accepted. ;-) It would be interesting to see it re-calculated with the accurate weight. His average height is also estimated at around 8 feet if that helps. No records exist to indicate his foot size however the do appear to be disproportionately large for his size.

According to the Marvel Wikia he can easily lift 90-100 tons. Tons in all their forms are about 1000 kg and on Earth weights go like ~10 Newtons = 1 kg, so he can easily muster 1000 kN of force when lifting. This suggests that he's plenty capable of enduring the now-600 kN of force from his legs that he needs to jump to the top of a 120m building. It still takes him about a meter to do it, and he now produces 6 MPa of pressure on the ground -- less if his feet are much larger, but again he might jump from the balls of his feet, decreasing their surface area. The only surprising thing is that he goes from 0 to 120 mph in at most two meters of pushing (assuming he somehow ducks down to the point where his center of mass is only 2ft above the ground -- that makes this an upper limit). That means that he completes the jump in only about 75 milliseconds, or half of a human reaction time. You have to imagine that he ducks down, and then before you can blink, he is already off with full automobile speed flying into the air. The effect on the ground is basically the same as a car at 70 mph crashing into a concrete barrier; you can see a couple cars crashing into walls done by the Mythbusters at this link: https://www.youtube.com/watch?v=r8E5dUnLmh4 https://www.youtube.com/watch?v=r8E5dUnLmh4 The wall escapes pretty much unharmed, though I don't know what it's made out of. The question posed is whether the concrete cracks, and it really depends on what's beneath the concrete. The problem is that concrete is basically made up of packed rocks held together with glue. This gives it an odd structural property: it is much easier to pull it apart, structurally speaking, than it is to compress it. Concrete does very well under compression, very poorly under tension. Bending a slab of concrete means putting compression on the near side, where the rocks have to come together, but putting tension on the far side, where stuff bends outward and apart. Whether the Hulk breaks the concrete depends very strongly on what's happening on the outward side -- does it generate cracks which propagate all the way up through the concrete? That's much harder to answer.
