Expanding Foam for Pole Setting (Discontinued)

The Steren 250-750 Expanding Foam for Pole Setting is a hydrophobic 2-part polyurethane composite backfill that expands to fill the peripheral void between a utility/fencing pole and the hole. It forms low-density, high-strength composite that can structurally support the pole and maintain its upright positioning. It expands immediately after mixing and reaches 50% of full strength in approximately 3 minutes and is fully cured in approximately 2 hours. This concrete replacement is equivalent to three 50 lb. bags of concrete.
