Why do buildings on permafrost have potential structural issues?

Question

Responses

Most thermosyphons don't work properly when installed.

Ground level permafrost is usually very stable, unlike deeper levels of permafrost.

There are not enough geotechnical engineers available to design these buildings.

The heat from buildings melts the ice in the permafrost below and the water is then displaced.

Answer 1

This displacement can cause the ground to shift, leading to potential structural issues. Additionally, the freeze-thaw cycle can also weaken the soil and create instability for the building foundation.
