From our offices in Fairbanks and Anchorage, we have advanced the field of foundation design and construction in permafrost conditions. Pioneering the design and use of a passively refrigerated gravel pad foundation using flat-loop thermosyphons, we have designed a variety of foundations and earth structures. We model thermal conditions using state-of-the-practice software with consistently accurate results.

In Alaskan arctic and subarctic conditions, we have performed underground petroleum spill investigations and designed and operated site cleanup measures, including free-product recovery, groundwater treatment, vapor extraction, air sparging, and bioremediation. We've conducted contaminant characterization and remedial design at many sites underlain by permafrost and have designed and installed pressurized monitoring wells through permafrost, in which air pressure is used to depress the water in the well below the bottom of the permafrost, preventing the well from freezing.
