Chaps,
Hypotehtically speaking if you'd moved into a house with a short but very steep drive that requires to be reversed into because it's tighter than a tight thing and it's slabs so prone to getting slippy when it's frosty. Where would I get a sack of grit to put on it to mean I can actually get up it and down it without sliding into the folk across the roads front garden. And before somebody says it I will be parking on the street when I have to! All I've seen so far is building sand which I thought might be a bit too fine.
