Hello all:
Today I demo-ed my front porch steps. There were 7 steps, a little over 5′ wide, made of concrete, with brick in the rubble fill and inside the retaining walls. I don’t know how old the steps were, but it’s a brick house from 1915.
Unfortunately, nothing with any strength remained to build on, so I am starting from scratch – a big open patch of earth in front of the porch.
I am not sure which is the best way to proceed from here. Ultimately, I will face everything with brick, and put limestone treads down, but I am not sure what is best to do under that.
Do I pour a couple of footings perpendicular to the porch, form out the stairs, fill some rubble in the middle, throw in some rebar, and pour concrete? I have done this a couple of times before, although on a somewhat smaller scale. What worries me about this is the materials cost and grunt work of so much concrete.
Or do I build out of block? I have not done a stair like this before, and I have the following question: What kind of footing is required for a set of steps built of block? A thick slab below? Something else?
I’ve got a picture of the job…if only I can find that adapter for the camera…will post it later.
Thanks for any input.
Alex

You need some sort of footing. How much depends on conditions, Frost heave? Expansive soils? Very dry location? Very wet location?
Presumably with the age of things the soil is well-settled, and you know from the previous steps how much things tend to move. If the steps were still pretty much in the right place then things are prety stable. If the steps had walked several inches or broken into pieces that separated then the soil is a bit of a problem.
I should have mentioned that I am in New York City (cold winters), and the steps had settled a bit. However, there was nothing all that solid under them to begin with.
I am aware that there needs to be a footing - what I would like to know is how is it typically done under a block stair.
Thanks,
Alex
