Re: [Plumbing] Frozen water service line

said by mattmag:

To make things worse, the current warming trend (if you can call it that) is only going to make the problem WORSE. Warming soil above frozen soil will force the freezing action even deeper, so don't think you are off the hook if it gets nicer out.

I don't understand how warming the soil near the surface could make the soil below freeze deeper.

I don't fully understand it either, but anyone who deals with this situation around here will concur that it can make it worse. From the limited explanation I received when I asked, it has to do with the upper levels of soil thawing which then releases moisture that migrates downward toward the colder soil, and in turn re-freezes, and that expansion is what helps move the frost line lower in depth.
