Builders' sand for drainage?

Hello Nick
NM As Cormaic pointed out, builders' sand has not had salt in
NM it for many decades - at least not if bought from an even
NM half-respectable person.
They don't wash it at the quarry, and that's where I get mine from.
I'm a bit hazy about the geology side - I guess sand comes from both
sea and river sources, so if former it would surely have traces of
salt in it?
But I must admit, I've never licked it so can't say.
The tens of thousands of years that's been there, any salt would have
been leached out, whatever the source.
