I used Styrene foam packing blocks for all of my mountain base on my layout.  It’d incredibly strong and very light.  I covered the foam with Paper Mache but I wouldn’t recommend it, it shrinks about 5 to 8% as it dries.
 
Plaster of Paris works very good as a cover as does Sculptamold, neither skrink.

Are you talking the stuff made of beads? It does get messy if you cut or shape it. It's also not generally as structurally stout as the pink or blue extruded styrofoam, depending on what it's molded into. So if you can stand the messiness, it can be used if properly supported.

Is there anything wrong with using molded packing styrofoam for molding hills and mountain sub-structures?
