How thick is the base?

It's 400 grams in a 9" tin

I think the base is rather thick; how are you prepping the pan? Spray? Butter? Are you using a springform pan or two piece cheesecake pan? Are you using only digestive biscuit crumbs or are you adding some graham crumbs in there as well? How much butter/crumb/sugar?
