expansion joints

I'm a few degrees north of you, and I can tell ya, a flat, smooth stretch of county road can turn into a roller coaster, in the dead of winter. And while the frost line's only about 30" most of the winter, for 2-3 weeks every winter, it drops below -20F, and when it does, the ground heaves alot. It's worse where theres more moisture in the ground!

Moisture in the ground. What's that?

Frost heave:

That might be settling of backfill against the foundation. If it's a full basement the overcut to dig the hole is 5' and nobody's brave enough to compact it because you can blow out the wall doing that.

That was my guess on that one, too.

Whatever you guys want to believe was the cause is pretty much irrelevant, it is a perfect example of why expansion joints are used under meters.

I didn't hear either one of us say it wasn't although if it settles enough you will need an extra few inches of wire along with some more conduit.
