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. Two-year shelf life. Pole Setting Foam can be used not only for setting poles, but is also designed for moisture barrier protection in handholes with large amounts of water present. Expanding foam for use in setting poles or for building a moisture barrier in the cable entry section of a cross connect cabinet. Also reference: 79698 Cardboard Template for Moisture Barrier Kit used with Pole Setting Foam for building moisture barrier in the cable entry section of a cross connect cabinet. Place template in handhole opening and pour foam. Instructions for installing the Moisture Barrier Kit available as a PDF download on this page. Pole Setting Foam saves money and increases efficiency. It replaces traditional methods of backfilling distribution poles, transmission poles, and decorative street lighting during installation. Pole Setting Foam is a hydrophobic, two-part polyurethane foam, that 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 and hardware can be strung after 15 minutes. 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.
