Pole Setting & Straightening Foam

OsmoSet^® High-Density Foam

Pole foam offers many benefits over soil, including greater compressive strength, but it is especially useful for:

• Rocky soil and dynamited or drilled pole sets that may not produce sufficient backfill material
• Sandy or sandy loam soils with low compressive strength
• Difficult-to-access pole sets where transporting fill dirt is not feasible

OsmoSet is a high-density, polyurethane, water-blown foam designed for setting and straightening distribution and transmission poles. Because OsmoSet foam completely encapsulates the pole, it greatly reduces preservatives leaching and soil contamination. It contains no chlorofluorocarbons (CFCs) or hydrofluorocarbons (HFCs), making it safe for both the applicator and the surrounding environment.

Benefits of OsmoSet

• Added Strength and Safety - Most soils in the U.S. have a compressive strength of approximately 28 PSI. OsmoSet foam – with a density of 5 lbs/ft3 – has a compressive strength of over 100 PSI, providing an increased safety factor over the surrounding natural soil of nearly 4:1.
• Labor Efficiency - Using foam is less labor intensive than backfilling with soil. There is also no need for tamping, which reduces back strain and injuries.
• Reduced Environmental Impact - OsmoSet eliminates the need to transport backfill material to the job site and reduces the potential leaching of preservation from the pole to the surrounding soil. The hydrocarbon footprint is also a benefit.
• Reduced Costs - OsmoSet expands at a ratio of 18:1, 20% more than other foams, which means less product is required to fill the space. 
• Easy to Store & Transport - The patented package design of OsmoSet includes Part A and B mixtures in D-shaped containers that conveniently fit with a mixer inside the mixing pail. This efficient design reduces freight and shipping costs and makes the product easy to transport and store at the job site.
