Rainbow Technology Pole Setting Foam - 9 Cubic Foot Kit 79709

A hydrophobic, two-part polyurethane, expanding foam, designed to rapidly provide intermediate backfill for setting utility poles.
It forms a low-density, high-strength foam that can structurally support the pole and maintain its upright positions. Hardware may be strung after 15 minutes. Serves as a barrier impending the migration of preservation materials into the surrounding soil and ground water. Pole Setting Foam saves money and increases efficiency. It replaces traditional methods of backfilling distribution poles, transmission poles, and decorative street lighting during installation. Expands to fill the peripheral void between a utility pole and the hole. Pole Setting Foam displays excellent adhesion to most pole materials, including wood poles treated with pentachlorophenol, CCA, ACA, etc. and without the use of primers. After mixing, it foams immediately and reaches 50% of full strength in approximately 3 minutes and 80% within 60 minutes. Once poured, Pole Setting Foam expands approximately 15 times its original volume and sets the pole in 3 minutes, creating a proven solid foundation material. It removes the need to backfill by traditional methods and the “tamping” associated with it. Pole Setting Foam significantly reduces labor requirements as no backfilling is required. Because Pole Setting Foam is hydrophobic, its physical properties will not be affected by wet soil or small amount of standing water in the hole; however, we recommend the standing water does not exceed 2 inches with the structure in the hole.
Features:

Superior to stone in resistance to overturning and equal to crushed stone against uplift Eliminates the need to transport heavy rock and stone backfill
Hardens quickly (10 – 15 minutes) with compressive strengths three to four times that of tamped soil Poles are set faster, thus restoring service to the customer quicker and with added strength
