I have a potential project in a permafrost area. I have little info known yet on the site. We would like to have an underground concrete bunker for equipment. Customer has fear of installing an underground bunker due to chance of uplift of the bunker. An idea I have that I wanted to get some feedback is as follows: Could we counter act the buoyant forces that could happen if the ground thaws by basically weighing the bunker down with a thick floor slab?
In addition I would be utilizing insulation under the foundation to help prevent heat transfer to the soil, along with a thick gravel base.
