i think i'd spread decomposed granite over the entire floor, roll it 
out with a heavy roller, scoop up everything that would scoop, sweep, 
and not worry about it.  if worse came to worse i'd flood the swept 
floor with polyurethane for a seal coat and not worry about it.  packed 
decomposed granite is very, very stable.  limestone sand is also quite 
stable, so you could use that, instead.
