Limestone basement walls crumbling

I have a 100 year old house with what I can assume is limestone basement walls. Every month or so, I have to vacuum the floors around the edges b/c the walls crumble, leaving a fine sand on the floor. When I try to brush the walls, it seems like it will never end. Some area are really bad and you can see actual stones and some areas are fine and completely flat. Is there any type of product I can put on the walls to even them out and end the crumbling?

After 100 years how far back did this start if only in the past few years what changed?
If things like exterior foundation wall was repaired or coated, painted
or any other changes were made it could affect the interior side.
Sounds like moisture is migrating to the interior side.
Check out the following products:

Thanks for the ideas! We've only lived here less than 3 years so I'm not sure how long it's been going on. It looks as though the previous owners put Ugl on the walls at one point but that hasn't helped. I'm going to give that Prosoco stuff a try!
