Filling an existing CMU wall

Filling an existing CMU wall

Filling an existing CMU wall

(OP)
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

RE: Filling an existing CMU wall

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.

RE: Filling an existing CMU wall

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?  

RE: Filling an existing CMU wall

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