PASSIVE GROUND FREEZING TECHNOLOGY: WORLDWIDE LEADERSHIP, INNOVATION, AND
EXPERIENCE.

For over 40 years, Arctic Foundations, Inc. has provided its customers and
teaming partners rapid, well-conceived solutions to geotechnical problems
through the application of their proprietary ground freezing technology.

The company analyzes, designs, manufactures, installs, and operates heat
transfer and ground freezing systems that enhance the engineering
characteristics of soil and rock. Strengthening soils, controlling water, and
immobilizing water borne hazardous contaminants are typical benefits to
end-users. AFI systems are designed for the long-term and may well outlast the
structures they are supporting or protecting.

An exemplary understanding of the interrelationship of diverse engineering
disciplines and many years of development and operational experience allows AFI
to offer its clients superior systems with lower life-cycle costs than its
competitors.


WELCOME TO ARCTIC FOUNDATIONS INC

As the arctic, sub-arctic, and antarctic regions of the world are developed, one
of the major engineering and construction obstacles is the permafrost. Our
frozen lands are a design challenge to planners, engineers, and contractors.

Climatic changes and surface damage due to development have caused thawing and
degradation of this frozen ground. Repeated thawing and freezing causes heaving,
sloughing, and creeping. It can destroy foundations in a matter of seasons.

SOLUTIONS...

Realizing the need to maintain permafrost and the advantages of freezing
previously thawed unstable ground, Erv Long developed the Thermopile system in
the late 1950's.

Working at that time for the US Army Corps of Engineers, Long patented his
passive thermal transfer process. The first commercial units were installed by
the Corps in 1960. These installations at the Aurora communication site are
still functioning today.

With hundreds of installations and thousands of units designed, manufactured and
installed, AFI has been the leader in state-of-the-art passive ground freezing
and thawing systems.

As development continues in the unstable arctic and sub-arctic areas, these
systems have become more refined and improved. In addition to providing the
premier foundations for buildings, tanks, towers, and other structures on
permafrost, AFI has designed and worked with many aspects of the permafrost
stabilization problem. They have developed frost-proof bench marks for use by
surveyors, pioneered controlled thawing techniques to eliminate frost and frost
heave in some areas, and worked extensively on stabilization of land-slide
areas. Their experience also includes deployment of impervious frozen barriers
to confine hazardous waste and control groundwater, passive freezers, geothermal
heating, and water supply dams.
