The crawl space should have a wall on all sides, this would help contain dirt under slab. I’ve never seen construction as in your picture.


Good luck

Never mind the crawl space, the SOG should have a perimeter foundation.

Hard to tell from one pic. But my guess is this is a slab on grade that should not have a crawl space. Like you mentioned the dirt has erroded away. Recommend a foundation person.

That looks like the rare and elusive levitating slab.


A special fix would be required. I would expect something along the lines of injecting concrete slurry below the slab. If I were providing the fix I would be concerned with how many other locations like this under the slab and how to locate them. Refer to a foundation expert for further evaluation and repair recommendations.

How about this Jon?


"Undermined foundation noted at slab on grade adjacent to crawlspace area. The unsupported slab at this area is danger of cracking. Recommend further evaluation and repair by a licensed foundation contractor"

What if the new buyer isn't concerned about some "cracks" in the concrete?

I like this response:

"Undermined foundation noted at slab on grade adjacent to crawlspace area. Recommend further evaluation and repair by a licensed foundation engineer/contractor"

Curtis,


I have sat in at presentations by lawyers that say you are at risk of being sued if don't tell them what might happen if they don't address the problem. I always try to state the issue, state the possible consequences of not addressing it, and recommend who to call to fix it.

How about this? "Undermined foundation noted at slab on grade adjacent to crawlspace area. The unsupported slab at this area is danger of collapsing. Recommend further evaluation and repair by a licensed foundation contractor"

Thanks a lot guys: The deal fell through on this one, but I might run into this again, I have a feeling we had a contractor in the area back in the 50’s and 60’s that used this technique.
