Building materials used to minimize road damage

Applications for our insulation products are endless.  Building materials and techniques to minimize the damage from thawing permafrost are being used in cold climate regions.

R-Tech insulation sheets will help minimize thawing in the future.

Roads have been rebuilt with the same sheets of R-Tech insulation one would normally use in a building envelope (walls and roofs).  Officials spent a little extra money to lay 4 inches of insulation underneath an Alaska roadway near Fairbanks, which was damaged by thawing, before repaving it.

The forces involved in freeze/thaw cycles are extremely powerful, and can result in serious damage of surfacing materials.  In permafrost regions the insulation is used to maintain the sub-grade in a frozen state during the summer period.  Insulfoam insulation has been used successfully in Alaska for its ability to retain critical structural properties in a  severe freeze/thaw environment.  It has been demonstrated that it retains its load carrying ability.  Insulfoam insulation has been used in Alaska for numerous commercial, industrial and residential applications such as:

  • Road and highway base
  • Permafrost protection
  • Foundations
  • Waterlines & septic systems
  • Drill pads and mud pits
  • Freezer slabs
  • Railroad base
  • Under slab
  • Utilidors
  • Plazas and parking structures
  • Ice rinks
  • Cold Storage
