I've noticed some spots on my basement block walls that seem to be disintegrating. When I touch those areas, dust or sand comes off, which is concerning. I'm planning to contact a foundation company for advice, but I wanted to know if anyone else has experienced this strange fraying of block walls. Should I be worried about it? It can't be a good sign, right?

It sounds like what you're experiencing could be efflorescence, which is often a sign of water intrusion. That buildup is usually a result of moisture mixing with the salts in the cement. Make sure to keep an eye on it, as it could indicate bigger moisture issues in your foundation. You might want to gather some more info before the foundation experts come in—maybe snap some pictures to show them too!
Definitely keep an eye on it! It's concerning when walls start crumbling. Since you mentioned that dust or sand comes off, make sure to check for water damage, as that can lead to more serious issues down the line. You might want to look into sealing any cracks temporarily until you can get someone to assess it professionally.
