[General Fantasy] What do Dwarves do with the leftover stone from building their cities?

Take Esgaroth for example, or Moria. These are *massive* Dwarven cities carved from the insides of a mountain. What happens with all of that raw stone material that's been cut and carved away? I'm sure some of it is re-purposed, but what about the rest? It is literally a *mountain's worth of rock*. Where does it go?

Where do you think humans get the stone to build their cities? Quarried stone is one of the biggest exports of Dwarven kingdoms. It's not as glamorous as Mithril or Gems, but it far more plentiful, and everyone needs it.
