I never thought of putting the stairs next to the house. I'll have to knock that around in my head for a while--thanks for the reply.

Propane tanks are in the way--nice thought though!

Re: Problem making concrete stairs


Just a couple thoughts:

- I'd consider corbelling some 4" or 6" block behind the wall, yet still on the footing, to create some support for the back side of the steps. 4-5 points in the whole length would likely be more than adeqaute.

- Consider overhanging the steps 3-4" over the face of the painted wall. This will help out with the cantilever issue, look finished, and the block will fair better in the long run without water running down it constantly,

- I would only focus on filling the cores of the block with rebar in them, the non-rebar cores will add no strength to the wall.

- I would pour the grouted cores separate of the steps, so that the finished concrete DOES NOT lock into the block below, only the rebar bent into the concrete. Too many unpredictable re-entrant corners that will likely cause random, unsightly cracking in the steps.

Thanks for the reply--I am understanding somewhat your suggestions but since I am not that familiar with this kind of construction can you help me with some photos/drawings of the "corbelling" that you mentioned? My main concern is how to get the corbel to attach to the existing wall that we have already built.

You do all the math off the height 72/8= 9 but 8 is just to big for code so you redo that with 10 72/10= 7.2" and the bottom riser would be 5.7"
8" riser is the maximum code in my neck of the woods.

If your not worried about space then forget my post.

Hey Ron, thanks for your post.

I have had two knee replacements several years back. Unfortunately, even though I do not have pain like I had before the replacement, I do not have the range of motion that I had prior to surgery. So I would like to keep the riser around the 7-1/2" range. That number is comfortable for me. The old railroad ties that I installed years ago was okay before my surgery but now I want something with less height. (plus the ties were rotting and bug infested)
