MudJacking / Concrete Leveling in SOMD?

Trying to fix a situation with my landing and steps before it becomes a big problem. Have a 4 to 6 inch void under the concrete, which hasn't sagged or cracked yet (being held up by foundation). Want to fill it with support material before it pulls my foundation wall apart.

I don't think we can just fill the area with dirt/gravel as it will still compress some and would be hard to force in with enough pressure to be supporting of the cement. So I think injecting more concrete (the expanding kind) or poly foam like they do to lift sunken concrete would be a good solution.

Problem is, I can't seem to find anyone who does this in Southern Maryland. I don't want to demo and redo my otherwise perfectly fine landing and stairs.

If you know of anyone who performs this service, please let me know.

I looked years back and virtually nobody does it outside the urban areas.

That's what I noticed. I was hoping someone who does cement work down here might have the equipment even if they don't advertise the service.

For the poly-foam it looks like it's a $300-400 investment in equipment and a couple hundred in foam, more than I would like to spend as a DIY project. I don't know what required for the mudjacking but it's probably similar.

I wonder if it would be possible to use a funnel, PVC pipe, and some epanding concrete mix to try to do it from the side. Not something I would try to tackle myself, or have the husband do, but possibly something a handi-man might be willing to try.
