Concreting 1in 25 fall?

[B R C]

Have a pad to do in front of a shed 5m deep 17m width with a fall at on end of 1 in 25 reducing to about 1 in 80 at the other end. Presumably need to tell readymix the slope or ask for a particular slump? Also it would be easier to tamp top to bottom rather than across as lorry can back in and I can put a beam across where load ends so no no waste, or is tamping across better?

1 in 25 isn't to bad. 75/80 slump

Tamp which ever way. I prefer across the slope
