Concrete pad on sloping ground

[/pine]

If you live in a freezing zone you might want to get some air entraining agent if you are mixing yourself...

Nice job on the forms and rod. This should make you a very good pad.

Thanks for the advice!

I'll be mixing the concrete with a mixer I picked up for my TC-30, so I should only have to deal with the weight twice - unloading it from the trailer and dumping it into the mixer. However, I'll definitely ask on the price of the 60 lb bags.

I had a bit of time to work on it this weekend and snapped a couple of pictures.

The ground is pretty hard and dry here with a lot of caliche, and driving in 2x4s is pretty much out of the question; on the plus side, the ground doesn't crack. The T-posts seem to hold well, although I'll have to cut them off at the top in order to get the mixer in there.

I finished the first level of rebar and am adding a partial second level no higher than 3" below the top of the form. I'll probably add a bit of gravel to the bottom of the footer, as I made it a few inches deeper than I needed to.

Since everything is overkill already, you could just put the second layer of rod in after pouring the concrete. Just take a shovel and push it in about 3"s deep right after pouring. Easier to form and pour it this way.

It may just be the picture but, are your forms level?

The picture makes it look waaaay off. A 1/4" drop along the 5' length would be more than plenty for a slab that size and really not necessary.

I don't think they're far off, probably just the photo and bad angle. I laid a straight edge across and then a level on the straight edge. The bubble is between the lines, but probably sitting on one line. Easy enough to check again.
