1500 sq ft crawl with 600sq ft of basement, every thing looked fine until I got to the far corner and saw this.

Am I wrong or is that just a rat slab that broke because of poorly compacted fill?

If that's the case, then it borders on non-issue.

Isn't that a moisture barrier under the thin layer of concrete? It looks to me like someone decided to dump some excess concrete in the crawl rather than form an actual slab. If the footings are still OK then the areas where the concrete is covering the JM panels might be more of a concern than where it has dropped down.

Just random thoughts...I really don't know whats going on there. It's weird!!!

Added...Just saw Chad's "rat slab" comment. I've never heard that term, but I think I know what he means.

Around here, rat slab means there's just enough concrete to hold down a vapor barrier and to keep rodents out. Crawl slabs are typically 2 inches thick.

We call it a 'skim coat' or some will say 'skin coat'. Around here, there is always a poly vapor barrier laid down first, then a coat of concrete is mostly to protect the poly from damage and to make it nice for home inspectors. Not nice for rats. I get it.

The damage in the picture is not structural, but it shows a lack of care, especially enclosing the lower edges of the wallboard. That has created a channel for termites, I think?

It's way over the border, well into the middle of non-issue land.

Richard,

They call 'em "rat walls" around here. Don't ask me why, since it isn't a "wall" at all, but that's what some old timers told me when I first got into this gig.

You never know, there might be a big 'ol stump under that the's rotted away and allowed that cavity to form. Couldn't say until could see more of it. Weird looking situation with the JM stuff. What kind of configuration is that anyway?

ONE TEAM - ONE FIGHT!!!

A rat wall is a thin vertical trench filled with concrete around the perimeter of a grain storage facility; kinda like a foundation wall that isn't bearing a load. Kept rats from tunneling into the grain storage area.

At least, that's what we called them on the farm.
