Sand for binding?

[sinbad197]

Hello all,

I have just finished compacting the hardcore for my extension and was wondering what type of sand i use for the layer above?

Sorry for what might be an obvious question but thought it better to ask rather than have the BCO asking me to remove a tonne of it.

Many thanks !
