Ive poured a concrete slab floor awhile back and unfortunately it's not entirely level with it declining around 30 to 40mm over 5m.
What would you recommend for levelling it?
I have a half ton bag of ballast and half ton bag of builders sand left over I was hoping to use. I'm tempted to use the builders sand but I know that's not recommended.
