Filling an existing CMU wall

[SRO]

I have an existing hollow cmu foundation wall with a substantial point load bearing on it. I want to fill the cores of the wall solid at these locations, but it's in a crawlspace, and there are many locations. I am aware of injecting on concrete to repair cracks, but is there anything similar to this that will fill in the cores solid without damaging the existing CMU's?

Thanks

Can you get access to the wall?
Yon can remove a face shell at locations to be filled..

Yes, you can access it through a crawl space. The contractor was trying to avoid installing temp posting in the finished 1st floor while he broke open the blocks. I was looking to find some sort of epoxy that could be pumped in a couple of 1"-2" holes in each core.

Why can't you use a "pea gravel" (3/8" stone) mix and pump it into the cores through a 2" diameter hole with a standard grout pump?

For CMU foundation frost walls, is it normally required to fill all cells below grade with grout in a cold climate?
