I have done a fair amount of cement work over the years. Mostly flat
areas or very slightly pitched. But I have a section of grass between
two poured slabs that gets pretty muddy at times and it leads to my
barn, so I am always walking there. I want to pour a sidewalk in
there, but leave part of it grass. It's only about 8 or 9 feet long,
but it drops about 10 inches in this span. Because I will
occasionally lead a horse thru there, I'd prefer not to make a step,
not to mention I often walk out there at night and it's pretty dark
back there and I know I will trip on it unless I am always carrying a
flashlight (and half the time I cant find them). So, I'd prefer to
just follow the slope of the soil thats there now. The problem is
this: If I pour a slab with that amount of slope, wont the cement all
pool to the lower end of the slope? Should I just keep working it
back up until it begins to set, or should I put 2x4s every 3 feet
until it sets and then pull them out and fill in the gaps? Whats the
best way to do this?
One other thing. I dont want this cement smooth, or it will become
real slippery in winter when it ices over. I know the trick to run a
coarse broom over it after its set, but I think that is still not
rought enough. How can I make it rougher? No, I dont want to pour it
and not trowel it, leaving all the stones exposed. Thats too rough.
I was wondering about troweling it and pulling a leaf rake across it,
or something like that, Something that would make an "X" pattern
would be ideal. I guess the roughness should be similar to the side
of a concrete block.
Then too, there's another thought. Would I be better off using patio
blocks? (I mean the 4" thick, not the 2" which crack too easily esp
if a horse walks on them. I'm not sure how well they would work on a
slope like that ???
Make your soup with far less water than you would use so it is stiff
and needs to be really pounded into the forms and it won't go rolling
down the hill after you trowell the surface sweep it with a broom.
As far as the slope, a fairly dry mix will not present a problem. If you
are getting delivery of redimix, let them know.
If you are mixing on site, make it dryer than you think it should be and
it will probably be fine.
You might check with the local material yard and see if they rent
the forms for imprinting brick joints in the surface. You could
make one if you have a welder.
For doing this process, you'd probably want to
pour small sections.
Well, for 8 feet long and , maybe, 4 feet wide, a single sheet
of OSB nailed to the top of the side forms would make a good
top of a mold....
This may be more trouble than it's worth, and I really go for
the idea presented of have a really stiff mix and just working it
till it starts to set.... HOWEVER.... if you pour cement into a mold
and wait till it firms up and then remove the top and trowel it, that
might work also....
I found the answers here very interesting as I have wondered
about the same problem.....
Up to now, I have just put down black plastic and about 6 inches
of gravel or base rock. It works really well, is cheap, and easy
Just my two cents worth,,

If your concrete (not cement) is running down a 10 inch incline in 9 feet,
you have WAY too much water in the mix. Unlike the stupid scenes in the
movies where concrete is as watery as soup, concrete should be stiff and be
difficult to spread. Too much water makes concrete weak, crumbly, easy to
wear down and subject to a lot of cracking. Think of Gunite, where they
spray concrete on vertical surfaces such as pools, and it stays there. If it
was even slightly watery it would slide down to the bottom.

If you cover that area with an impermeable surface, you're
likely to end up just moving the mudhole to the lower
edge of it. I think you'd be better off plowing out the topsoil,
and replacing it driveway gravel. And maybe laying some drain
another concrete alternative:
you could spread a thin layer of small gravel over the problem area. Grass
will grow up through it. Add more from time to time until the muddiness
finally goes away. You can get a pretty firm base built up (as far as foot
traffic anyway) that grass will tolerate just fine.
I have a parking area that's covered with pea gravel and my truck sits fine
on it all year, and it looks like the rest of the lawn.
Around here, they press an expanded piece of metal into the concrete at
sidewalks where they slope down to the street. This leaves a diamond
grid pattern, which is deeper than brooming the concrete.
I'd think you could find such a beast at a supply store or maybe a tool
Exposed aggregate concrete is done by washing the top layer of concrete
off, after trowling and finishing. A smaller, decorative aggregate is
used, its like large pea gravel. (I got to watch a big patio being made
