Default Builders' sand for drainage?

Hello Nick

NM When laid down, sea sand would contain salt, but almost all
NM sources will have been washed clean. There is probably
NM salty sand in the UK, but it will not be sold unwashed by
NM respectable builders' merchants, as the salt interferes with
NM cement and other uses and salty sand does not meet the
NM relevant standards.

But that does assume you bought it from a builders' merchants.

Anyway, wondering way off topic now. OP's sand would've been washed
adequately by being left outside for three years.
