Apparently there's tech called a thermosyphon to keep permafrost under foundations frozen. https://mass.pbslearningmedia.org/resource/nvmms.sci.phys.permafrost

  That's mentioned in the article, alright: > If temperature monitoring or visible deformations tip maintenance workers off in time, structures can be saved. Thermosyphons were installed to cool the soil under the apartment block at 36 Nansen Street when temperature probes showed warming there, for instance. > But sometimes changes come too suddenly. A brick office building on Komsomolskaya street cracked like an egg one September morning in 2009 and stands empty to this day. A top corner of the building pitched forward 70cm, sending jagged fissures up the middle of its facade and squashing windows.

  Interestingly, "termosifone" is the Italian word for the cast-iron radiator, used to heat homes.
