Is there any way to save the crumbling sandstone walls in my basement?

The walls are literally crumbling. I'm wondering if someone has had the same problem and has a solution. I don't think applying plaster or stucco will help.

you may need to consult with a structurel engeener..should be able to locate one or have the city building inspector come and evaluate. -

You need Cement Sealer, and a couple of coats of it! You will need to lightly brush the loose dust and pieces off first, then spray the sealer on. Don't brush again, but let each light coat dry thoroughly. Keep applying coats until you are satisfied that no more shedding is coming from the walls and you can run your hand over the surface without any dry roughness -

Consult a professional. Basement walls should not be crumbling. -

Definitely contact a concrete foundation professional. They may need to pour a concrete foundation against the sandstone or a concrete block foundation based on cost and budget. I remember rebuilding stone foundation walls with my dad using concrete blocks. You may also need the foundation walls waterproofed on the outside. Water and moisture may be what is causing it to crumble.
