My ex-girlfriend has a porch with a set of 3 nicer than average cement
steps, I think 3 feet wide (maybe 4, I can check). The steps are most
likely hollow, right?

The porch is where it was, but the steps have sunk 4 to 6 inches.

Is there any way to lift the steps back to where they were? I think
the porch has a cement apron in front, as tall as the steps were.

I had in mind using 10 long 2x4's to lift the thing up, maybe oiling
the porch apron and the wall next to the steps with something, or
using a pry bar, so the steps would slide up along side the porch and
wall. Then when it is up there, filling the hole with cement, or
with big and small rocks (and gravel)and cement.

Do you think this would work, and since it is more work than I want to
put into an ex's house, do you think we can talk a contractor or a
handyman into doing it this way? I have a feeling most will want to
break up the old steps, cart them away, build forms and pour new
steps. These seems like it would cost much more money and her old
steps are nicer than average. Each step has a lip on 3 sides
overhanging the risers and the sides, that are attractive and give a
person more space to put his foot.

If the project fails, it will only sink a little at a time I think and
no one will get hurt. And it probably won't sink as low as it is now.
Now her mother has to go around back and enter the house a half-flight
down, then walk up another full flight, because she can't make it up
the step that is 4 or 6 inches higher than normal.



As to cement, I was helping someone years ago who had to erect some
thin poles, 20 feet by 2 or 3 inches (some of each), and he told me
that he used to mix up the cement and pour it in the hole to
stablilize the poles, but someone told him all he had to do was put in
the pole and hold it in place, pour the dry quickrete into the hole
and then pour in a bucket of water, and everything would harden up
well enough for his purposes. It's been 10 years since he did this
and everything is fine, so it must be true.

Does anyone else have experience with this fly-by-night technique,
and how big a volume do you think could be done this way?

Specifically, I'm wondering if this could be enough to hold the steps
above. This would mean we wouldn't have to have cement or concrete
delivered, and wouldn't have to mix it ourselves.
