Re: Why Sand Between Paving Stones?

 
Exactly. Of course, you could embed them in concrete instead. Concrete
looks more professional, resists weeds, and can be stronger, however
concrete costs a lot more, is more difficult to install, and is harder to
repair if the paving shifts and cracks.

  Per GeekBoy:

In Germany, I've seen entire roads made out of paving stones. But
the stones are different from the ones I see in southeastern
Penna.   The stones used around here are all rectangular.

The stones I see used for roads and driveways in Germany are sort
of Z-shaped.    I sat beside an access road made out of the
things and could hear them rattle as cars drove over them.  No
sand - they were, to some extent, loose.
