pouring up hill

is it better to start at the top and fill in the area or start at the bottom first? and what is the best way to keep the concrete from sloping back down so the pad stays even? the pour raises about a foot in a 10 foot width.

Pour the pad with a very low slump (less Water ask the driver of the truck) and start at the bottom and work your way up so the concrete has something to lean on, is this pad level or going to follow the grade of the hill, if it is screed up hill for the final screed.
Good Luck

I agree with Frank99 about the slump of the concrete.

Stiffer is better for sloped work.

But I prefer starting the pour at the uphill most location because you can use gravity to assit you in screeding concrete by pulling it downhill rather than pushing it up.

Pour top down, not bottom up.

Would just like to point out the "Slump" will be determind by the batch plant. You need to specify what you want. Tell them at the plant when you make your order just what you are plans are and,they should be able to help you. The driver can always add moisture to the mix.

Now if you are using a Redi-Mix truck(truck that mixes on site) then the driver\operater will set the slump.

In my experience, if you screed wet concrete downhill (from top to bottom), gravity and elasticity will result in a very thin layer at the top unless it is VERY dry when poured. There is a fine line in reference to the "slump" when pouring on a slope as it needs to be wet enough to be workable yet dry enough to not slide when screeded and floated. Might be advisable to have some experienced/professional help....concrete is permanent and can be a "monument to your ignorance".
