Concrete on a slope

Concrete on a slope

Concrete on a slope

(OP)
Hi Guys

I have in the past seen concrete being pired on slopes, generally not an issue, just reduce the slump. I have a case where the slope is 2:1, i.e. 2m horiz/1m vertical. Could this be problematic and what tips could you offer for pouring on a slope.

In this case the slab is 15m long on the slope from top to bottom.

RE: Concrete on a slope

Keep the slump low and keep the placement rate slow.  Work side to side and up the slope.  Don't let placement occur up and down the slope before going side to side.

RE: Concrete on a slope

We place concrete agitation ramps on 2:1 slopes on a regular basis. Like Ron said, low slump and from the bottom up. I think we typical end up using 3-4" slump concrete. It will be difficult to finish if you are looking for anything other than a screed finish.
